Tool Parameter 24: Undercut Angle - Siemens SINUMERIK 840D sl Function Manual

W1: Tool offset
18.4 Tool cutting edge
Tool basic length 1 to 3 (tool parameters 21 to 23)
In order that the discrepancy between the toolholder reference point F and the toolholder
reference point F' can be corrected on the three geometry axes (three dimensional), all 3 basic
lengths are active irrespective of the tool type. In other words, a twist drill (tool type 200) with
a tool length compensation (length 1) can also have a tool base dimension/adapter dimension
in 3 axes.

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.
