Circular machining

Select Single cuts
Select Circular machining (counterclockwise)
Alternative: Select Circular machining
(clockwise)
Select the scope of the cycle:
Circular machining: The tool moves in a circular arc from the Start
point X, Z to the End point contour X2, Z2 at the programmed
feed rate and remains at the cycle end position.
Circular machining (With return): The tool approaches the
workpiece, executes the circular cut and returns to the Start point
at the end of cycle. Tool-tip radius compensation is taken into
account.
Cycle parameters:
X, Z: Start point
X1, Z1: Start point contour (if With return is active)
X2, Z2: End point contour
R: Radius
G47: Safety clearance (if With return is active)
T: Tool number – turret pocket number
G14: Tool change point (if With return is active)
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
190
Off: When the cycle is completed, the tool
remains at the cycle end position
On: The tool returns to the starting point
