Contour spigot residual material (CYCLE63, option)

Function
When you have milled a contour spigot and residual material remains, then this is automatically
detected. You can use a suitable tool to remove this residual material without having to machine
the whole spigot 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 clearing.
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 spigots and want to avoid unnecessary tool changeover, clear all the spigots
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 blank 1
2. Contour spigot 1
3. Clear spigot 1
