Contrary to stock removal, theplunge turning function allows you to machine contours that the tool must enter vertically.You will need a special tool for plunge turning. Before you program the "Plunge turning"cycle, you must define the contour.Set machining area limitsIf, for example, you want to machine a certain area of the contour with a different tool, youcan set machining area limits so that machining only takes place in the area of the contouryou have selected.Feedrate interruptionTo prevent the occurrence of excessively long chips during machining, you can program afeedrate interruption.
