During grooving 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. Material that remains as part of the finishing allowance is not residual material. The
"Grooving residual material" function allows you to remove unwanted material with a suitable
tool.
