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, 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.
