Contour pocket residual material (CYCLE63, option)

Function
When you have removed stock from a pocket (with/without islands) and there is residual
material, then this is automatically detected. You can use a suitable tool to remove this
residual material without having to machine the whole pocket again, i.e. avoiding
unnecessary non-productive motion. Material that remains as part of the finishing allowance
is not residual material.
The residual material is calculated on the basis of the milling cutter used for stock removal.
If you mill several pockets and want to avoid unnecessary tool changeover, remove stock
from all the pockets first and then remove the residual material. In this case, for removing the
residual material, you also have to enter a value for the reference tool TR parameter, which,
for the ShopTurn program, additionally appears when you press the "All parameters" softkey.
Then program as follows:
1. Contour pocket 1
2. Solid machining
3. Contour pocket 2
4. Solid machining
5. Contour pocket 1
6. Solid machine residual material
7. Contour pocket 2
8. Solid machine residual material
Procedure
404
Software option
For solid machining residual material, you require the option "residual
material detection and machining".
1. The part program or ShopTurn program to be processed has been
created and you are in the editor.
2. Press the "Milling", "Contour milling" and "Pocket resid. mat." softkeys.
The "Pocket Res. Mat." input window opens.
3. For the ShopTurn program, press the "All parameters" softkey if you
want to enter additional parameters.
