10.5 Contour milling
The residual material is calculated on the basis of the milling cutter used for stock removal.
It is also possible to run multiple residual material steps one after the other. In this case, the
milling tool should be selected to be smaller by a factor of no more than 3 for each new step.
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, when removing the
residual material, you must also enter a value for the reference tool TR parameter, which, in the
ShopTurn program, additionally appears when you press the "All parameters" softkey. When
programming, proceed as follows:
1. Contour pocket 1
2. Stock removal
3. Contour pocket 2
4. Stock removal
5. Contour pocket 1
6. Removing residual stock
7. Contour pocket 2
8. Removing residual stock
