Undercutting type K
Call the recessing cycles
Select undercut K
This cycle performs only one cut at an angle of 45°. The resulting
contour geometry therefore depends on the tool that is used.
Type of machining for technology database access: Finishing
Cycle run
1 Pre-position at an angle of 45° to safety clearance above the
contour corner point X1, Z1
at rapid traverse
2 Plunge by undercut depth I
3 Return the tool to the starting point on same path
4 Move to the tool change point according to the G14 setting
Cycle parameters
