Undercutting type H
Call the recessing cycles
Select undercutting H
The contour depends on the parameters defined. If you do not define
an undercut radius R, the oblique cut will be executed up to contour
corner Z1
(tool radius = undercut radius).
If you do not define the plunging angle, it is calculated from the
undercut length
and undercut radius. The final point of the undercut
is then located at the contour corner.
The end point of the undercut is determined from the plunging angle
in accordance with Undercut type H.
