11 Set the nesting parameters (See Figure 16)

a) In the Parameters Group, input the Edge Width: 3.0 mm

This parameter defines the shortest distance between part and the coil boundary b) Input Bridge Span: 5.0 mm

This parameter defines the shortest distance between blanks

12 Open the Constrains page to set the parameters for coil and blank and click

Blank Range button to unfold the Range option and Cut-off die option

13 Note: These parameters constrain the size of coil as well as the angle and width

of the blank placed on the coil If these parameters are not defined, the program will calculate the desired nesting result according to the default angle range and

width range In this tutorial, please use the default angle range and width range

setting for calculation (See Figure 17)

14 Click Cal. to display the Calculator dialog box Set ID to 240 and OD to 940 (See Figure 18) The length of the coil will be calculated automatically Click OK to exit the Calculator dialog box

box is enabled Click this button to start nesting

calculation (See Figure 19)

17 View the nesting result (See Figure 20)

After the completion of nesting calculation, all the

possible nesting results are shown in the results list

The default display in the graphic area is the nesting

result with the maximum material utilization under

the default constraint condition The user may click

the other results in the results list for display in the

graphic area The user may also return to to set the

parameters and re-calculate nesting

18 Output nesting result

The Report button at the bottom of Nesting dialog box is

enabled (See Figure 20) Click this button to output the result

(See Figure 20)

a) Click Filename to input the specified file name of report

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 Apply button at the bottom of Nesting Report dialog

box (See Figure 21) The program will automatically write in

the report in *.htm format to the specified file, as shown in
