Trim Line Estimation

1 Start up Dynaform 5.9.2

2 Click FileOpen and select \Tutorial_

3_triming_line_estimation\MSTEP_Model4.df file

3 Click FileSave As (See Figure 3)

5 Click Save to save the database

6 The data model is shown in Figure 5 In the file of this case, there are meshed

models, products, flanges and formed CAD surfaces

1 Click PartsTurn on to display four Parts in the database: DIE1, DIE2,

PRODUCT1 and FLANGE

2 Toggle on Only Select On option and click on DIE1 and DIE2 respectively As

shown in Figure 6~9, a complete drawing die face is composed of DIE1 and DIE2

FLANGE is the flanging part

4 Toggle off Only Select On option and simultaneously open DIE2 and FLANGE As shown in Figure 14, Flange, which is counted from the die fillet of DIE2, share the same boundary line with DIE2 This boundary line will be defined as constraint in the subsequent operation

II Check Part in Database

1 Toggle off Surface

2 Select UserSetup -> Preprocess (See Figure 15)

3 Select Model Check/Repair and Click Boundary Display icon（the second icon

in the first row）(See Figure 16)

4 Toggle off Elements and Nodes

5 Click (free rotation) to rotate the model

6 Click (clear highlight) to make sure that each part only has one complete

boundary line (See Figure 17 and 18)

7 Click to display the model in isometric view

8 Click Auto Plate Normal icon (the first icon in the first row) (See Figure 16)

model

10 Select Yes to make sure the mesh normal direction of each part is consistent

11 Click Exit to dismiss the dialog box

12 Click OK to exit Model Check/Repair dialog box

III Mesh Check and Repair

1 Click BSETrim Line to enter MSTEP solver Click Sheet button (See Figure 19)

2 The New BSE Project dialog box will be displayed (See Figure 20) Click OK to

enter Tool Preparation (BSE) interface Click Define Tool button (See Figure 21)

3 Click Undefined button in the displayed Define Sheet window (See Figure 22)

4 Select FLANGE as the corresponding part of blank then click OK to exit Select

Part window (See Figure 23)

5 Click Exit to exit the Define Tool dialog box (See Figure 24)

6 Click the BLANKMAT button to display the Material window (See Window 25)

7 Click Material Library button and select DQSK(36) material (See Figure 26 and

Figure 27)

8 Clicking OK to complete the material definition (See Figure 28), the word

BLANKMAT is changed to DQSK, which indicates that the material parameter

definition is completed

9 Define the sheet Thickness: 1.2 mm (See Figure 27)

10 Click OK to exit the Define Sheet window, the program will automatically go to Tool Preparation (BSE) window (See Figure 28)

Define Tool button (See Figure 31)

12 Click DIE2 and click OK to exit Select Part window (See Figure 32)

13 Click Exit to exit Define tool window (See Figure 33)

14 Click Exit in the displayed Tool Preparation (BSE) window (See Figure 34) The program will automatically return to MSTEP window, the color of Sheet and

Curve Binder changes from red to green (See Figure 35)

15 Click Advanced button in MSTEP window (See Figure 36)

1 Click Run button in the MSTEP window to run MSTEP solver (See Figure 38)

V Start up Mstep Trim Line

After the MSTEP calculation is completed, DYNAFORM will automatically read in

the computed sheet blank unfold outline and add it to a new part There are two

more parts in this case: OUTLINE is the trim line unfolding to the drawing surface

as shown in Figure 39 and Figure 40; SURFBDLN is the trim line with boundary

line of the original flanging surface as shown in Figure 41 and Figure 42
