18.4.9 Tool parameter 24: Undercut angle
Meaning
Certain turning cycles, in which traversing motions with tool clearance are generated, monitor the tool clearance
angle of the active tool for possible contour violations.
Value range
The angle (0 to 90° with no leading sign) is entered in tool parameter 24 as the tool clearance angle.
Figure 18-9 Tool clearance angle of the turning tool during relief cutting
Machining type, longitudinal or transverse
The tool clearance angle is entered in different ways according to the type of machining (longitudinal or face). If a
tool is to be used for both longitudinal and face machining, two cutting edges must be entered for different tool
clearance angles.
