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. The finishing allowance should be set identically for all machining steps
because it does not count as residual material.
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
