4 The BSE-in-NX Blank Size Engineering plug-in for All Current Versions of NX is designed to be used with thin sheet body parts, it is recommend that the part’s midsurface is used with the BSE-in-NX. After installing BSE-in-NX 2.0, the user must place the license file ‘eta.lic’ in the "startup” sub-directory of the “BSE-in-NX2.0” installation folder. If dealing with solid parts or surfaced parts consisting of both sides of material including thickness surfaces, then the geometry will need to be prepared before accessing the BSE-in-NX functions. BSE-in-NX will display a warning upon detection of solid models, and instruct users to first prepare the geometry. Two methods for preparing part geometry for use with the BSE-in-NX are described in this training tutorial, covering both Midsurface generation for Solid Parts (See Slide 28) and Geometry Extraction for Surfaced PartsSlide 28 (See Slide 31).Slide 31 BSE-in-NX 2.0 Introduction 4

5 1.Start up NX. 2.Click the File menu and select Open. See Figure 1. 3.Select the file path and file name, and then click the OK button to open the database. We will open the file named BSE_in_NX_case.prt here. See Figure 2. 4.Select Modeling module in Start menu, see Figure 3.(Or click shortcut key: Ctrl+M.) Open NX Database Figure 1 Figure 2 5 Figure 3

6 Figure 5 Figure 6 Figure 4 Note: The BSE-in-NX functions can also be accessed via the BSE-in-NX drop down menu. See Figure 4. 6 Add BSE-in-NX Plug-in to Menu & Toolbar 1.Right click in the Toolbar Region to display a list of installed Toolbars. The BSE-in-NX option should be listed near the bottom. See Figure 5 2.Toggle on the BSE-in-NX toolbar. See Figure 4. 3.The BSE-in-NX toolbar icons will open on screen (Figure 6), and can be dragged to the desired toolbar docking location (see next slide)

7 Click the Unfold Part icon to begin the process. If a solid part is detected, users will be warned to first generate a middle surface before continuing. If no warning is displayed, or if the part is already a thin sheet body, then continue to the next slide to begin the Part Unfold process. If the warning message is displayed, or if working with a surfaced part consisting of both sides of material including thickness surfaces, then please skip to the suggested part Model preparation methods beginning on Slide 23Slide 23 7 BSE-in-NX Best Practice Introduction

8 1.Click the Unfold Part icon ( ), and the Unfold Part dialog box will be displayed, as illustrated in Figure 7. 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 8. Figure 7 Figure 8 8 BSE-in-NX 2.0 Begin Unfold Process

9 Figure 9 3.Select HSLA350 as the material. See Figure 9. 4.Click the OK button to exit the Material Library dialog box. 5.Key in the blank thickness: 2.0(mm). 6.The Unfold Part interface is illustrated in Figure 10 after it is defined. Figure 10 9 I. Define Material and Thickness

10 1.Click the Define Sheet button to display the Class Selection dialog box, as illustrated in Figure Click the Select All button and the selected faces will be highlighted, as illustrated in Figure II. Define Blank Figure 11 Figure 12

11 3.The Class Selection dialog box will display “105 objects selected”, as illustrated Figure 13. Click the OK button in Class Selection dialog box to exit the Class Selection dialog box, and the program will automatically mesh the part. 4.Toggle on the Mesh Display option to display the meshing result, as illustrated in Figure 14. Figure II. Define Blank Figure 14

12 1.Click the Run Mstep button (Figure 15) to run MSTEP, the DOS window will be displayed, as illustrated in Figure III. Blank Size Estimate Figure 16 Figure 15

13 2.MSTEP calculation result is illustrated in Figure After MSTEP calculation result is completed, the Report button will be activated, as illustrated in Figure III. Blank Size Estimate Figure 18 Figure 17

14 Figure 19 1.Click the Report button to open the Formability Report dialog box, as illustrated in Figure 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. Figure IV. Generate Formability Report

15 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 parameters a)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 V. Blank Nesting Figure 21

16 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 Click the Apply button to begin the nesting calculation. 16 V. Blank Nesting Figure 22

17 9. View nesting result. After completion of nesting calculation, all the possible nesting results are displayed in the detail list. See Figure 23. 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 %, as illustrated in Figure 24 (next slide). Figure V. Blank Nesting

19 1.Click the Manual button to open the Manual dialog box, as illustrated in Figure 25. The blue feature points will be displayed in the nesting result diagram, as shown in Figure Select the blank to operate, and use the rotation and translation buttons to manually manipulate the nesting result, as shown in Figure VI. Manual Nesting Figure 26 Figure 25 Figure 27

20 3. Click the Manual Operation button to activate the dynamic manual control interface, as shown in Figure Move the mouse around the blue feature points until the hinting arrow is displayed, as shown in Figure Click the left mouse button once on the desired feature point, and move the mouse to dynamically manipulate the nesting result, and left click again to complete the operation. 6.Click the Back button to return to the Manual interface, or click Cancel to reset the changes. The result for this manual operation is illustrated in Figure 30. Figure VI. Manual Nesting Figure 29 Figure 30

21 1.Output Nesting Report The 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 31), and the program will automatically write in the report in *.htm format to the specified file, as shown in Figure 32(next slide).
