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)
