Undercut. Form H
Select Recessing cycle
Select Undercut H
The contour depends on the parameters defined. If you do not
define the Undercut radius, 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 lgth. and Undercut radius. The end 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.
Cycle parameters:
X, Z: Start point
X1, Z1: Contour corner
K: Undercut lgth.
R: Undercut radius (default: no circular element)
W: Plunging angle (default: W is calculated)
G47: Safety clearance
Further information:
T: Tool number – turret pocket number
G14: Tool change point
Further information:
ID: ID no.
S: Cutting speed or Constant speed
F: Feed per revolution
MT: M after T: M function that is executed after the tool call T
MFS: M at beginning: M function that is executed at the
beginning of the machining step
MFE: M at end: M function that is executed at the end of the
machining step
WP: No. of spindle – Displays which workpiece spindle is used
to execute the cycle (machine-dependent)
Main drive
Opposing spindle for rear-face machining
BW: Angle in the B axis (machine-dependent)
CW: Reverse the tool (machine-dependent)
HC: Shoe brake (machine-dependent)
DF: Miscellaneous function (machine-dependent)
