Select
Undercut U
This cycle machines an
Undercut type U
and, if programmed,
finishes the adjoining plane surface. The undercut is executed in
several passes if the
Underc. breadth is greater than the cutting
width of the tool. If the cutting width of the tool is not defined, the
control assumes that the tool’s cutting width equals the
Underc.
breadth . Either a chamfer or a rounding arc can be machined.
