Recessing cycles<br />

Undercut H<br />
This cycle machines a “Form H” undercut. The workpiece is approached<br />
at a safety clearance. If you do not enter a value for W, it will<br />
be calculated from K and R. The final point of the undercut is then<br />
located at the “final point contour”.<br />
Information on the cycle parameters:<br />
R: Undercut radius – default: no circular element<br />
W: Plunge angle – default: W is calculated<br />
Undercut K<br />
The resulting contour geometry depends on the tool that is used.<br />
Cycle run<br />
1 Pre-position at an angle of 45° to safety clearance above “corner point<br />
contour X1, Z1” in rapid traverse.<br />
2 Plunge-cut at an angle of 45° – the path of traverse is calculated from<br />
the parameter “undercut depth I”.<br />
3 Retract to “start point X, Z“ on same path.<br />
This cycle does not take any cutting radius compensation<br />
values into account.
