to edit the definition. The
Mill Window tab opens.
11. On the Options tab, select Inside window contour and click OK.
12. On the Model Tree, click the sequence
CONSTANT_LOAD and then click
to open the
PLAY PATH dialog box.
13. Click
to play simulation.
14. On the Model Tree, click
Mill window 1 and then click
to edit the definition. The
Mill Window tab opens.
15. On the Options tab, select Outside window contour and click OK.
16. On the Model Tree, click the sequence
CONSTANT_LOAD and then click
to open the
PLAY PATH dialog box.
17. Click
to play simulation.
18. On the Model Tree, click the sequence
TYPE_SPIRAL and then click
to edit the definition. The
HSM Rough tab opens.
19. On the Parameters tab, set values as shown for the following parameters and then repeat steps 3–6:

◦ REMOVE_CORNER_PEGS = YES
1. REMOVE_CORNER_PEGS is set to NO.
2. REMOVE_CORNER_PEGS is set to YES.
20. On the References tab, click the Mill window collector and on the Model Tree, select Mill Window 3.
21. On the Parameters tab, set values as shown for the following parameter and then repeat steps 3–6:
◦ BOTTOM_STOCK_ALLOW = 0
◦ MAX_STEP_DEPTH = 8
◦ MACHINE_FLATLANDS = NO
1. MACHINE_FLATLANDS is set to YES.
2. MACHINE_FLATLANDS is set to NO.

Working with Rest Roughing Options
In the following steps, you will work with parameters that are unique to Rest Roughing.
1. On the Model Tree, click the sequence
RE_ROUGH_PREV_TOOL and then click
to edit the definition. The
HSM Rest Rough tab opens.
2. Click
and select
SF16_R1_ISO50 tool with a cutter diameter of 16 mm.
On the References tab, the Reference Cutting Tool automatically collects the previously used tool SF30_R1_ISO50.
3. On the Parameters tab, the parameters are populated automatically, based on the tool diameter. To optimize the toolpath, set values as shown for the following parameters:
◦ STEP_OVER = 8
◦ MAX_STEP_DEPTH = 5
◦ ROUGH_STOCK_ALLOW = 1
◦ BOTTOM_ROUGH_STOCK_ALLOW = 1
◦ PREVIOUS_ROUGH_STOCK_ALLOW = 1
◦ PREVIOUS_BOTTOM_STOCK_ALLOW = 1
4. Click arrow next to
and then click
. The
Material Removal tab opens.
5. On the Material Removal tab, click Stock Model > Open In-Process Stock. The Load stock dialog box opens.
6. Select rough.bin and click Open.
7. Click
to open the
Play Simulation dialog box.
8. Click
to play simulation.
|  When you use a previous tool to calculate the tool path, limitations, such as tool length and holder geometry affect the rest roughing sequence. In such scenarios, you can generate more accurate tool paths by using the previous stock. |
9. On the
Material Removal tab, click
and then on the
HSM Rest Rough tab, click
OK.
10. On the Model Tree, click the sequence
RE_ROUGH_PREV_STOCK and then click
to edit the definition. The
HSM Rest Rough tab opens.
11. On the References tab, click the Mill window collector and on the Model Tree, select Mill Window 1.

References tab, in the
Rough Stock File collector, click
to import the rough stock file. The
Open dialog box opens.
13. Select rough.stl and click Open.
14. On the Parameters tab
, click
. The
Select Step dialog box opens. The
RE_ROUGH_PREV_TOOL sequence is selected.
15. Click OK to copy parameters and repeat steps 4–9.
