The cycle parts the workpiece. If programmed, a chamfer or
rounding arc is machined on the outside diameter.
Cycle parameters:
X, Z: Start point
X1, Z1: Contour corner
XE: Inner diameter (pipe)
D: Maximum speed
I: Diam. feed reduction – limit diameter over which traverse is
at reduced feed rate
B: -B cham./+B round.
B > 0: Radius of rounding
B < 0: Width of chamfer
E: Reduced feed
K: Retraction distance after parting – lift off the tool laterally
from the plane surface before retraction
SD: Speed limit from I up
U: Collector active diameter (machine-dependent)
G47: Safety clearance
Further information: "Safety clearance G47", Page 180
T: Tool number – turret pocket number
G14: Tool change point
Further information: "Tool change point G14", Page 180
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: Cut
