8.5.8 Stock removal residual (CYCLE952)
Function
Using the "Stock removal residual" function, you can remove material that has remained for
stock removal along the contour.
During stock removal along the contour, the cycle automatically detects any residual material
and generates an updated blank contour. For a G code program, for stock removal residual
material, "Yes" must be programmed. Material that remains as part of the finishing allowance
is not residual material. Using the "Stock removal residual material" function, you can
remove unwanted material with a suitable tool.
The "Stock removal residual material" function is a software option.
Procedure
1. The part program to be executed has been created and you are in the
editor.
2. Press the "Turning" and "Contour turning" softkeys.
3. Press the "Stock removal residual material" softkey.
The "Stock removal residual material" input window opens.
