VIII.Blank Outline Management

1 Click the Nesting button on the Outline interface

2 Select nesting type: Two-Up Nesting (the second icon) (See Figure 29)

3 The program will automatically define Outline as the blank outline for blank

nesting

4 Setup nesting parameters

a) Type in Edge Width:2.0 mm in Parameters Group This parameter defines the shortest distance between part and edge boundary

b) Type in Bridge Span:5.0 mm This parameter defines the shortest distance between blanks

c) Type in Addendum: 5.0mm This parameter is used to set up the addendum

of the blank

5 Click Constraints to set the parameters for strips and blanks

Note: These parameters restrict the size of strip and the angle when placing blank

on the strip 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 to calculate

6 Click Fix Width to adjust the width, input the value of 590 as the nesting width (See Figure 30)

7 Click Apply to start nesting calculation (See Figure 31) 22

8 View Nesting Result

After the completion of nesting calculation, all

the possible nesting results are displayed in

the results list The default display in graphic

region is the nesting results with the max

material utilization under the default constraint

The user can click on the other results in

results list to display them in graphic region Or,

the user can also return to set up the specific

parameters and recalculate nesting (See

Figure 32 and Figure 33)

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 Apply button at the bottom of Nest Report
