Teach-in | Recessing cycles
Undercut. Form K
Select Recessing cycle
Select Undercut K
This cycle performs only one linear cut at an angle of 45°. The
resulting contour geometry therefore depends on the tool that is
used.
Cycle parameters:
X, Z: Start point
X1, Z1: Contour corner
I: Undercut depth
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)
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 X1, Z1 at rapid traverse
2 Plunge by Undercut depth I
3 Return the tool to the Start point on the same path
4 Move to the Tool change point according to the setting in G14
