Plunge-turning rest (CYCLE952)

Function
The "Plunge turning residual material" function is used when you want to machine the material
that remained after plunge turning.
For plunge turning ShopTurn, the cycle automatically detects any residual material and
generates an updated blank contour. For a G code program, the function must have been
previously selected in the screen. Material that remains as part of the finishing allowance is
not residual material. The "Plunge turning residual material" function allows you to remove
unwanted material with a suitable tool.
