Introduction
The Plasma Chamfering Unit is used to produce
vertical and chamfered edges for the assembly of
large components in, for example, shipbuilding.
The chamfering of the edges can be varied. This
means that it can cut not only to fixed set angles, but
it is also possible to vary them continuously during
cutting.
Various kinds of materials, alloyed and unalloyed
steels, can thus be processed with a high cutting
speed without affecting the required cutting and
angle accuracy.
The automation of many sequences which the
Plasma Chamfering Unit offers makes handling of
the machine considerably easier for the user. As a
rule, it is only necessary to take the values for
vertical cutting from a table. The controller adaptsitself to the angle that has been input. This means
that the user does not need to calculate those values.
The Plasma Chamfering Unit is operated together
with the NCE 520 Controller. It is assumed therefore
that the operator has a basic knowledge of this type
of controller. In addition the reader should
understand ESSI programming and the main
terminology of plasma cutting.

Layout of the Manual
A summary connected to this section states which
details must be input in order to produce a programfor the Plasma Chamfering Unit, and what the
Plasma Chamfering Unit will then be capable of.
In general, this manual has been laid out in such a
way that the user can obtain the required knowledge
for the programming of the Plasma Chamfering Unit
through examples, step by step, and he will be able
to produce his own programs as quickly as possible
without having to read through the entire manual.
Explanations for the individual steps should thus
make it much easier to understand the examples.
The reader is also put in a position where he is able
to program parts with differing inputs.
Tables for cutting speed and the stand-off distance
from the jet to the plate, the organisation table, etc.,
follow after these examples. In addition, the
technical connections which were only touched on
briefly in the examples are explained at this point
with the help of geometrical illustrations.

Plasma Chamfering Unit-Overview
Inputs / Settings by the User
+ In the case of a chamfered cut, there are always two contours of different
sizes in a component. The user should program the larger contour (visual
edge), regardless of whether this is located on the upper or the lower side
of the plate.
+ There is also thechamfering angle
+ and thelocation of the cut joint.
+ In the case of a variable chamfering angle, it is necessary to input astart
angleand anend angle.
+ x The values forcutting speed,
+ x thewidth of the cut joint
x and thestand-off distance between the burner and the tool are the
same as for a vertical cut.
+ x It is also necessary to input thethickness of the sheet.+ In order to maintain sharp corners when cutting, it is necessary to
program the so-called corner routines: one should cut approximately
10 mm beyond the contour in the same direction as the latter and,
together with a bevel, return to the next contour line in the form of a
triangle.
x Corrective values for any necessary deviations in angle and size are
given in an organisation program, which the user can produce or modify
according to his own requirements.

Capabilities of the Unit
The controller recognises from the position of the
cut joint and the signed value of the inputchamfering angle whether the programmed
contour is on the upper side or the lower side of
the plate and travels automatically for the required
amount of sideways offset of the unit.
The cutting speed that was input will be reduced
as the chamfering angle increases.
In the same way, the width of the cut joint is
adjusted with regard to the angle. As the angle increases, and the bevelling angle of
the burner increases likewise, the Plasma
Chamfering Unit is raised and offset sideways to
avoid a possible collision between the jet cap and
the material.
Execution of the corner routine likewise depends
on the angle and on the thickness of the sheet.
The cutting speed is reduced to the extent that the
Plasma Chamfering Unit can turn in the new
direction while it is executing the corner routine. In
doing this the Plasma Chamfering Unit does not
follow the contour line with the rotation but turns
directly from the direction of the most recently cut
contour into the direction of the following contour
of the part to be cut. This is achieved via a special
ESSI help function (HF 118).
A special corner technology achieves correct
execution of the corner routine even with minimal
or maximum sheet thickness or chamfering
angles.

The user merely needs to ensure that he has
included the corner routine when setting the
stand-off distance from the edge of the plate or
from a neighbouring part. Through the use of an organisation program, the
controller corrects for any possible inaccuracies in
angle and size which could be caused by the
cutting process or by the Plasma Chamfering Unit.

Examples forProgramming
The following examples are intended to illustrate the
previous details and help the user to produce his
own programs.
The solutions selected do not necessarily represent
the only option (see the list of ESSI help functions in
the help functions section), they are intended rather
to make the program sequences consistent to a
large extent so that the user is confronted with only a
small number of different cases. The programs
should in the main be produced with a(n) (ESAB)
programming system or directly at the controller.

Cutting of the parts begins after rapid traverse.
Before starting the actual contour cutting, the burner
which was still vertical for hole punching, places
itself diagonally to the set angle for the followingchamfer. Then the corner routine begins.
The burner sets itself upright again while carrying
out this routine. The remaining sides are cut
vertically. In detail, this is shown as follows:

Point 1
39 + 3175
The cutting speed can be taken from the tables.
Always start on the basis of a normal vertical cut.
This gives a cutting speed of 3175 mm/minute for a
thickness of 10 mm. The details in the table are to
be taken as guidelines, and other values may be
necessary according to the type of material.
The controller reduces the cutting speed
proportionally as the chamfering angle increases or
decreases, since the actual cutting length for achamfer is larger than that for a vertical cut.
This means that a vertical cut will be carried out at
the cutting speed that had been input, while the
Plasma Chamfering Unit operates as if one was
using thicker material when cutting chamfers.
29
The cut joint is located to the left of the contour.
Cutting is done in a clockwise direction (this involves
an external contour). HF29 is also used in all further
examples. The location (direction) of the cut joint
affects the input of the chamfer angle (+ or -).
51
The tangential controller is switched on. This insures
that the Plasma Chamfering Unit always follows the
contour and the set angle will always be maintained,
even in the event of a change of direction and also
for an arc-shaped contour.

76
A sensor is used for automatic height control when
cutting chamfers. This is done either by a feeler foot
or by an inductive sensor. The sensor senses at ashort distance from the jet (approx. 60 mm) from the
plate and ensures that the set stand-off distance
between the plate and the jet will be maintained in
the event of unevenness.
53
The plasma cycle is switched on and cutting can be
carried out.
122 + 200
A chamfering angle is input with this help function,
and the signed value affects the direction of the
angle (positive / negative angle).
Warning:
It is necessary to distinguish between input of
the angle (programmed angle) for the PlasmaChamfering Unit and the chamfering angle of the
(finished) work piece.
In the case of a work piece, a positive angle means
that the contour at the upper side is smaller than the
contour on the lower side of the sheet. The opposite
applies in the case of a negative angle.
Always enter the direction of the angle on the
Plasma Chamfering Unit with HF 122. In order to
determine this, you require the location of the cut
joint in addition to the chamfering angle of the work
piece: if the cut joint is to the left of the contour
(HF29), the chamfering angle to be input is the
opposite of the angle direction of the work piece.
You produce a positive angle at the work piece when
you program a negative angle for the Plasma
Programming of the Plasma Chamfering Unit 15Change index: 0 for NC Controller NCE 520 (GB)
Examples for Programming

Chamfering Unit. This assumes that the correct
cutting direction was taken into consideration when
programming the contour.
In the example, the positive angle (+200) that was
input takes effect, since a negative chamfer (-20)
was cut on the work piece.
If the cut joint is located to the right of the contour
(HF30), the signed value of the chamfering angle at
the Plasma Chamfering Unit and the work piece are
identical. You must input a negative angle if you
wish to cut a negative chamfer.
Point 1a
118
The Plasma Chamfering Unit does not, as is usual,
turn in the direction of the section which follows
directly after HF118 but turns instead in the
direction of the subsequent section.
In the example, the directions of the first section of
the chamfering and the subsequent first contour
element are identical. Help function HF 118 has no
effect in this case.
Point 2
The start is over, and the actual geometry will be cut.

Corner routine
Since the plasma jet always lags behind underneath
to some extent in the case of thicker sheets, the
corner of a part will already have been reached on
the upper side, while cutting has not yet reached the
corner on the lower side. A change of direction at
this point would produce a cutting-off or a
rounding-off of the lower corner. It is thus essential
for right-angled or acute angled corners, at least, to
be cut beyond the corner. This is done with a corner
routine. This is not (absolutely) essential for obtuse
angles (e.g. 120 and more). This depends on the
thickness of the sheet and the desired accuracy of
the corner.

Point 3
48
Automatic height setting is switched off 70 mm
before the new corner. This is essential when cutting
chamfers with the sensor travelling ahead, since it
can already be ahead of the edge of the plate before
the burner head reaches the corner. The stand-off
distance is a function of the distance between the
burner and the sensor, plus an additional margin for
safety.
77The feeler system with the sensor is turned off. It is
raised. In fact, HF77 selects height measurement
with a light beam, but this only becomes active once
the automatic height setting has been switched on
again.
Point 4
Here begins the geometry for the actual corner
routine. As a rule, it is adequate if you program a
length of 10 mm for the sides of the triangle. This will
be adequate in most cases through automatic
off-setting of the Plasma Chamfering Unit,
corresponding matching of the cut joint and a special
corner technique. In the case of very thick material
and large chamfering angles, a larger corner routine
may be necessary.
The cutting speed is automatically matched to the
slower cutting speed when the Plasma Chamfering
Unit is turning or setting an angle. This ensures that
there is enough time for both operations while the
bevels of the corner routine are being cut.

19/66
Point 5
118
HF118 is used at this point to avoid unnecessary
changes of direction. This is done by ensuring that
the Plasma Chamfering Unit only follows the actual
contour of the part and does not exceed the
maximum possible rotation, which would be the case
if executing only a corner routine (plus geometry).
While the bevels of the corner routine are being cut,
the Plasma Chamfering Unit turns in the opposite
direction, i.e. from the direction of the section whichled up to the corner routine, directly into the direction
of the following section.
122 + 0
The burner is set to the new angle, which is vertical
in this case, and likewise while the bevel is being cut.

Automatic height setting is switched on so that light

Point 9
(48)
Automatic height setting is switched off before the
end of the section. This is done for the same
reasons as for the corner routine. It is thus
absolutely essential when the last section is to be
cut with a chamfer.
The safety stand-off distance of 100 mm, instead of
70 mm as is used at the corner, represents a value
that is adequate for practically all cases. (If the firstside of the right angle is to be cut with a positive

chamfer, the section to be cut on the upper side of
the plate for the last section is in fact shorter than
that programmed.)
In the current example, HF48and the additional
stand-off distance are not essential. But
fundamentally you can operate with them for
simplicity.
(77)
The same applies for this function. It is essential if a
chamfer is to be cut, but in principle it can be used
for reasons of consistency. The sensor system isswitched off and light beam control is selected.
Point 10
(117)
This function ensures that the Plasma Chamfering
Unit maintains the direction of the last section, even
when the next section leads in another direction.
The reason for this application of HF117is the
same as the one for the use of HF 118 in the start
sequence and in the corner routine. An unnecessary
change of direction is avoided, and also the
possibility of exceeding the maximum possible
tangential rotation of the Plasma Chamfering Unit.
Since this ultimately only follows the exit path, the
Plasma Chamfering Unit can maintain the direction
without any danger. In the example, an exit is made
in the same direction as for the previous contour line
and HF117thus has no significance.
With the additional exit in connection with the
programmed contour, this ensures that the contour
is completely cut in every case, e.g., for each
chamfer (e.g., the first side vertical and the last side
with a negative chamfer), as in this case the plasma

Programming of the CuttingContour
When using the ESAB Plasma Chamfering Unit, theuser always programs the visual edge (larger
contour) for a part with a chamfer. He can thus
simply take the dimensional details from the
drawing, regardless of whether he wishes to produce
a positive or a negative chamfer.
In the case of a positive chamfer, the visual edge is
located on the lower side of the sheet. The controller
recognises this from the input by the user and is in a
position to take into account the difference in size
between the upper side of the sheet and the lower
side of the sheet by offsetting the plasma burner and
changing the cut joint.

Inputs to the Controller
After starting the program, a number of values are
requested at the controller though a menu. The
following details are also required in addition to the
details already input in the program example:
sheet thickness
cut joint
As can be seen from the menu, it is possible at this
point to enter the cutting speed as well. Other values
(sheet thickness or cut joint width) can likewise beentered in the program or at the menu.
Warning:
It is possible to enter values twice. In the event
of differing input values for the same parameter,
the programmed value must be deleted first,
meaning that a programmed value cannot be
corrected through a different value from the
menu. The programmed value must be deleted
first in this case.

The sensor for height measurement will be usedwhen cutting the first two sides (with chamfer), in
which case maintenance of the necessary stand-off
distance between the jet and the sheet will be
controlled by the light beam voltage for the
subsequent vertical cuts. The angle changes from a
negative to a positive chamfer at the first corner after
the first cut. The tangential controller remains
switched on while the entire program runs.

The end angle is to be entered in this form, i.e., the
angle that is to be reached after cutting off one or
more sections. The angle will vary equally from thispoint up to an end point that is still to be determined:
the Plasma Chamfering Unit changes its angle
during cutting via linear interpolation from +10to
+20. The result is a work piece with a negative
chamfer that begins with -10and increases to -20.

basis). This is automatically reduced by the
controller according to the chamfering angle.
Above all, the maximum speed of rotation is to be
noted for small circles and thin sheet. While the
controller reduces the cutting speed to the extent
that the rotation can be completely carried out,
cutting quality will suffer under certain circumstances.

List of Rules
In the case of acontour with a chamfer, the
larger contouris to be programmed. The following details must or can beentered into
the program(details in brackets):
Angle in 1/10
(Cutting speed) in mm/min
Location of the cut joint
(Cut joint width) in 1/10 mm
(Sheet thickness) in 1/10 mm
All the details in brackets that are not
programmed must be entered in the
menuof the controller before cutting.
Warning:Programmed values take priority.
The stand-off distance between the jet and the
sheet must beset at the machine, from which a
programmed cutting speed can be set
proportionally.
Take the values for vertical cuts as the values for
the cut joint (curve width), cutting speed and
stand-off distance between the jet and the sheet.
Technically related angles and deviations in size
can be equalised (see Section Organisation
Program for Plasma Chamfering Unit with NCE
520 NC Controller).

Thesense of height control(HF 76) is used
when cutting achamfer, and a light beam (HF 77)
is used for vertical cuts.
It is possible to punchholes diagonally(due tothe slag) or vertically. If you wish to punch holes
diagonally, theangle input(HF 122 .... ) must
be input before the beginning of the plasma cycle
and thusbefore HF 53, or otherwise afterwards.
Normally the cut joint (HF 29/30) is entered before
the first cut, i.e., before the initial chamfering. In
order to cut out an inner contour completely, it is,
however, meaningful to determine thecut jointafter the initial cutting.
The same applies if an outer contour or the start
do not have the same direction as the subsequent
contour.

In the case of avariable chamfer, an end angle
must also be input and theend of the variable
anglemust be indicated, as for example:
Only the so-called helping float functions may be
used between the end angle and the detail of the
end of the chamfer:
HF 47, 48, 76, 77.
Help functions 117 or 118 can or must be used at
all points at which there is a change of direction
which does not relate to the contour of the
work piece,in order to prevent the maximumrotational capability of the Plasma Chamfering
Unit being exceeded ( 405, standard).
117 - The Plasma Chamfering Unit retains the
direction for the next contour element,
which will for example be used before an
exit.
118 - The Plasma Chamfering Unit turns aboutthe shortest path in the direction of the
contour element which will be the next but
one. The element that was input
immediately after the HF 118 does not
follow the tangential controller.
HF 118 is used if a contour is to be cut
which does not belong to the parts
contour, such as the start or a cornerroutine.

In the case of acorner routine, the use of HF
118 is unavoidable for cutting (if the tangential
controller - HF 51 - is switched on). Without HF
118, the Plasma Chamfering Unit would turn ateach corner of the contour by 135, in other words
by a total of 270, while itonlyturns in the
opposite direction by90when usingHF 118.
Corner routines are requiredtopreserve sharp
cornerswith acute angles and right angles. In the
case of obtuse angles this depends on the
desired quality.
In most cases10 mmis enough for thesize forthe corner routine. In any case, the corner
routine must not be smaller than the cut joint that
had been input, plus the automatic offset plus any
corrective values from the organisation program.
A larger corner routine may therefore be required
for thick sheet and large angles.
A guidelinevaluefor thestand-off distance
between the part and the plate edge or to thenext partcan be taken by using double the
value of the corner routine. (Corner routine +
any stand-off distance of the cut joint + stand-off
distance for rotation of the Plasma Chamfering
Unit + safety margin for the path that will remain
stationary).

In the caseof achamfer, it is essentialto switch
offthe automatic height control in good time
before a corner, otherwise there is a danger that
the sensor could be located outside the plate orabove a neighbouring part (in the case of a feeler
foot sensor, no cut contour lines may be crossed).
The sensor is located approximately 60 mm
behind the jet. It is therefore adequate to switch
off the height setting70 mm before the corner.
Refer to Corner Routine in this section
concerning the sequence and position of the help
functions for a corner routine. Please note thefollowing:
Height setting may only be switched off in the
case of a feeler foot if this has already definitely
crossed the contour line that has already been cut.
Theheight setting mustlikewise beswitched
off earlier on the last contourof the cut section,
the guidelinevalue is 100 mm before the
corner, if one considers the case that the first
contour must be cut with a positive chamfer and
the last one with a positive or negative chamfer.

Inthe case ofa circle, you mustnot switch off
theheight settingbefore theend of the contour
of the part if the sensor is located such that it runs
just inside the circle, in the case of an outside
contour, and just outside the circle in the case of

If the side lengths for a part for which corner
routines must be cut are not greater than the
stand-off distance given above for switching off of
height setting, then height setting must not be
switched on. If thepartis simplytoo small, only
switch on height setting briefly(at the start).

Organisation Programfor Plasma Chamfering
Unit with NCE 520 NCController
An organisation program is used to compensate for
non-linearities during chamfer cutting.
Layout of an organisationprogram
An organisation program is an ASCII File with the
filename extension.ORG. Only capital letters,
numbers, minus signs, spaces and slashes may be
used in producing this file. Individual input values
must be separated from each other by at least one
space. A slash is used at the beginning to indicate a
comment line. All characters after the slash will be
ignored.
Organisation programs can either be produced on a
PC with an ASCII editor (such as EDIT.COM ), or
with the ANC editor. The ANC must be switched into
service mode for this purpose.
A distinction must be made between upper and
lower programming in the organisation program.
The relevant program time is determined by the
combination of the cut joint, side and the direction of
the bevel.

Upper programming: Kerf right (HF 30) and negative bevel or
kerf left (HF 29) and positive bevel
Lower programming: Kerf right (HF 30) and positive bevel or
kerf left (HF29) and negative bevel
A series of values for cut joint correction and
correction of the bevel can be input for each sheet
strength. A series of values must be available for
both upper and lower programming to provide cut
joint and bevel correction.The cut joint correction
values are input in 1/10 mm and the bevel
correction values in 1/10 .These characteristic
lines are described by four starting points (angles).
A characteristic line is interpolated in a linear fashion
between the individual starting points.

The NCE is able to run multiple organisation
programs. The software options available determine
which of the organisation programs is to be used.
The name of the organisation program to be loaded
can be input in the cutting package. If only one
organisation program is to be used, it is enough to
make the corresponding entry in the basic cutting
package (PARAM.CUT). If more than one
organisation program is to be used it is necessary to
use additional programmable cutting data. The
corresponding file names can be entered in the SDP
files.
The filename extension for organisation programs is
.ORG.The filename of the organisation program to
be loaded is input in the first cutting set description
line of the plasma process (N1) without the filename
extension. The syntax for this M = FILENAME. In
this example of an SDP file, the name of the
organisation program is N2FER_A.

Production of an organisation program for cut joint
and angle compensation in a plasma cutting unit:
1. Set all compensation values in the organisation
program to 0.2. Determine the cut joint for light beam control
(vertical).
3. Produce a test program for 4 test pieces with
angles 0, +10, +30, +45, and cut.
4. Evaluate the angles and dimensions, and enter
them into the organisation program.
5. Repeat the cutting with compensation values
entered into the program and correct as
necessary.
