BSE-in-NX 2.0 Overview

BSE-in-NX is a complete solution for accurately estimating blank size along with blank nesting for maximum material utilization, minimum scrap and piece costs—all within the familiar NX environment.

The solution can quickly produce a blank outline for blank size estimation along with piece price and scrap calculation.

Designed for cost estimators, blank predictions consider both linear bends and the material stretch that occurs during the forming process to produce the most accurate blank possible. The solution also provides for 1-up, 2-up and multiple blank nesting.

BSE-in-NX can also automatically generate reports, which include detailed descriptions of overall blank size, nesting configuration, pitch, coil width, material utilization, number of coils required to meet annual volume and total piece price for materials.

1. Click the Unfold Part icon ( ), and the Unfold Part dialog box will be displayed, as illustrated in Figure 1.

2. Click the CQ button under Material( Default Material CQ) to define the material, and it will display the Material Library dialog box. See Figure 2.

1. Click the Report button to open the Formability Report dialog box, as illustrated in Figure 11.

2. Click the Apply button to generate the formability report which is illustrated in Figure 20 (The file name of the formability report is Part file name_mstep.Suffix of file type and here the file name is BSE_in_NX_case_mstep.pdf ).

3. Click the Cancel button to exit the Formability Report dialog box.

IV. Generate Formability Report

1. Click the Nesting icon ( ) on the NX toolbar to display the Nesting dialog box.

2. The program will automatically define the last calculated blank outline (including any interior holes) as Outline 1

3. Users can re-define the blank outline clicking Blank Outline and selecting the desired profiles.

4. Select nesting type: Two-Up Nesting. (the second icon)

5. Set up nesting parametersa) Type in Edge Width:4.0 mm in Parameters

Group. This parameter defines the shortest distance between part and edge boundary.

b) Type in Bridge Span:10.0 mm. This parameter defines the shortest distance between blanks.

c) Type in Addendum: 5.0 mm. This parameter is used to setup the addendum of the blank. See Figure 13.

6. Click the Constraints button to set the parameters for strips and blanks.

Note: These parameters restrict the size of strip and the rotation angle of the blank when placed on the strip. If these parameters are not defined, the program will calculate the best nesting result according to the default angle range and angle step. In this tutorial, please use the default angle range and angle step to calculate.

7. Toggle on Fix Width to set the fixed width of the strip with 450, as illustrated in Figure 14.

8. Click the Apply button to begin the nesting calculation.

9. View nesting result. After completion of nesting calculation, all the

possible nesting results are displayed in the detail list. See Figure 15.

The first displayed result in graphic region is the nesting results with the max. material utilization in the defined constraint condition.

The user can click on the other results in detail list to display them in graphic region, or setup the specific parameters and recalculate nesting.

The highest utilization for the nesting result in this tutorial is 74.172%, as illustrated in Figure 16 (next slide).

1. Output Nesting ReportThe Report button at the right side of the detail list has

been activated. Click on this button to output nest.a) Click button to input the specified file name of

report, or specify paths of the report at the same time.

b) Enter Base Material Cost: 35 $/kg.c) Enter Extra Material Cost: 5 $/kg.d) Enter Scrap Material Cost: 2 $/kg.e) Enter Consumables Cost: 1 $/kg. Formula for calculating the cost of each blank :

Cost of each blank = (Base+ Extra) * weight of each blank – Scrap*(1- utilization)* weight of each blank

f) Click the OK button at the bottom of Report dialog box (See Figure 17), and the program will automatically write in the report in *.htm format to the specified file, as shown in Figure 18(next slide).
