10.3 Contour milling
If you mill several pockets and want to avoid unnecessary tool changes, 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
ShopMill program, additionally appears when you press the "All parameters" softkey. When
programming, you must then proceed as follows:
1. Contour pocket 1
2. Stock removal
3. Contour pocket 2
4. Stock removal
5. Contour pocket 1
6. Remove residual material
7. Contour pocket 2
8. Remove residual material
