Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Basic TasksThe Basic Tasks section explains how to create and modify various kinds offeaturesThe table below lists the information you will find

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Theme

Managing the Default ParametersThis section explains and illustrates how to use or modify various kinds offeaturesThe table below lists the information you will findUsing Sheet Metal Design assumes that you are in a CATPart document

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Editing the Sheet and ToolParameters

This section explains how to change the different sheet metal parameters

1 Click the Parameters icon The Sheet Metal Parameters dialog box is displayed

2 Change the Thickness if need be

3 Change the Bend Radius if need beConvention dictates that the inner angle between the two walls is used todefine the bendIt can vary from 0deg to 180deg exclusive This angle is constant and the bendaxis is rectilinear4 Press the Sheet Standards Files button to access to the companydefined standards if need be For more information refer to the Customizingsection

5 Click OK to validate the Sheet Metal Parameters

Modifying the Bend ExtremitiesThis section explains how to change the bend extremities

Click the Parameters icon The Sheet Metal Parameters dialog box is displayedThe second tab concerns the bend extremities

A combo box displays the six possible axial relimitations for the straight bendMinimum with no relief thebend corresponds to thecommon area of thesupporting walls along thebend axisSquare relief a square reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beRound relief a round reliefis added to the bendextremity The L1 and L2parameters can be modifiedif need beLinear the unfolded bend issplit by two planes goingthrough the correspondinglimit points (obtained byprojection of the bend axisonto the edges of thesupporting walls)Tangent the edges of thebend are tangent to theedges of the supportingwallsMaximum the bend iscalculated between thefurthest opposite edges ofthe supporting walls

These options can also be accessed through the pop-up button

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Defining the Bend AllowanceThis section explains the calculations related to foldingunfolding operations

When a bend is unfolded the sheet metal deformation is represented by thebend allowance V defined by the formula

L = A + B + V

whereL is the total unfolded lengthA and B the dimensioning lengths as defined on the figures below

bend lt 90deg bend gt 90deg

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

Wwall a feature created by adding thickness to a profile

Page 27: -Catia v5 Sheet Metal Design

Another way to compute the sheet metal deformation is the neutral fiberdefinition (K Factor)

W = α (R + k T)

whereW is the flat bend widthR the inner bend radiusT the sheet metal thicknessα the inner bend angle in radians

If β is the opening bend angle in degreesα = π (180 - β) 180

Physically the neutral fiber represents the limit between the materialcompressed area inside the bend and the extended area outside the bendIdeally it is represented by an arc located inside the thickness and centeredon the bend axis Therefore the K Factor always has a value between 0 and05

When you define the sheet metal parameters a literal feature defines thedefault K Factor according to the DIN standard

K = (065 + log(R T) 2) 2

This formula can be deactivated or modified using Knowledge Advisorworkbench

When a bend is created the bend K Factor and the bend allowance literalsare createdTwo cases may then occur

If the Sheet Metal K Factor has an activated formula and uses thedefault bend radius as input parameter the same formula is activatedon the bend K Factor with the bend radius as input

Else the bend K Factor is a formula equal to the Sheet Metal K Factor

The bend allowance literal is equal to a formula representing the use of thebend K Factor This formula is fairly complex and it is strongly recommendednot to delete it

V = α (R + k T) ndash 2 (R + T) tan ( min(π2α) 2)

Though it is possible to deactivate the formula to enter a fixed valueFinally the bend flat width is computed from the bend allowance value

PatterningIn this task you are going to create cutouts according to a patternCATIA allows you to define two types of patterns rectangular and circularpatternsThese features make the creation process easierOpen the Scenario3CATPartdocument from the Samplessheetmetal directoryThe Sheet Metal part looks like this

1 Select the cutout you want toduplicate that is the rectangular one

2 Click the Rectangular Pattern icon

The Rectangular Pattern Definitiondialog box is displayed Each tab isdedicated to a direction to define thelocation of the duplicated feature

Set the specification for the FirstDirection3 Select the Edge1 as shown tospecify the first direction of creationAn arrow is displayed on the wall

4 Click the Reverse button or selectthe arrow to modify the direction

5 Keep the Instances amp Spacingoptions to define the parameters

Choosing these parameters typesdims the Length field because theapplication no longer needs thisspecification to space the instances

6 Enter 2 as the number of instancesyou wish to obtain in the first direction

7 Define the spacing along the gridenter 30mm

Defining the spacing along the gridand the length of your choice wouldmake the application compute thenumber of possible instances andspace them at equal distances

8 Now click the Second Direction tabto define the other parameters

Note that defining a second directionis not compulsory Creating arectangular pattern defining only onedirection is possible

9 Select the Edge2 as shown todefine the second direction

10 Keep the Instances amp Spacingoption enter 8 and 10 mm in theappropriate fields

Additional cutouts have been alignedalong this second direction

PatterningIn this task you are going to create cutouts according to a patternCATIA allows you to define two types of patterns rectangular and circularpatternsThese features make the creation process easierOpen the Scenario3CATPartdocument from the Samplessheetmetal directoryThe Sheet Metal part looks like this

1 Select the cutout you want toduplicate that is the rectangular one

2 Click the Rectangular Pattern icon

The Rectangular Pattern Definitiondialog box is displayed Each tab isdedicated to a direction to define thelocation of the duplicated feature

Set the specification for the FirstDirection3 Select the Edge1 as shown tospecify the first direction of creationAn arrow is displayed on the wall

4 Click the Reverse button or selectthe arrow to modify the direction

5 Keep the Instances amp Spacingoptions to define the parameters

Choosing these parameters typesdims the Length field because theapplication no longer needs thisspecification to space the instances

6 Enter 2 as the number of instancesyou wish to obtain in the first direction

7 Define the spacing along the gridenter 30mm

Defining the spacing along the gridand the length of your choice wouldmake the application compute thenumber of possible instances andspace them at equal distances

8 Now click the Second Direction tabto define the other parameters

Note that defining a second directionis not compulsory Creating arectangular pattern defining only onedirection is possible

9 Select the Edge2 as shown todefine the second direction

10 Keep the Instances amp Spacingoption enter 8 and 10 mm in theappropriate fields

Additional cutouts have been alignedalong this second direction

The BendDefinition dialogbox displays adesign table forthe BendRadius

The defaultmode its to saythe formulaBend Radius =Part Radius isdeactivated

Lets see the Bend Radius Table using this icon

It shows the Bend Radius and the corresponding Bend Table

10 Click OK

If the Angle value is contained in the Bend Table the Bend Allowance uses thecorresponding valueIf not the Bend Allowance is computed according to the KFactorAn alternative if you use the V5R2 Sheet Metal Tables for example BNDTABL2the steps 1 to 4 are identical

5 Click the Design Table icon and select a line

6 Click OKThe parameter values are updated in the Sheet Metal Parameters dialog boxAt that time the parameters Thickness and Bend radius are driven by the designtableThey are now in gray indicating that you can no longer modify the valuesNote that if you create a bend there is no design table its the formula which is used
