Contour Spigot Residual Material (Cycle63, Option) - Siemens sinumerik 840D sl Operating Manual

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.
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 clearing.
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, 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 blank 1
2. Contour spigot 1
3. Clear spigot 1
4. Contour blank 2
5. Contour spigot 2
6. Clear spigot 2
7. Contour blank 1
8. Contour spigot 1
9. Clear residual material spigot 1
10. Contour blank 2
11. Contour spigot 2
12. Clear residual material spigot 2
