Cut longitud.—Expanded
Select Roughing cycles lon/trans
Select Cut longitud.
Select the Expanded soft key
Taking the oversizes into account, the cycle roughs the area
described by the Start point and the Start point contour X1/End
point contour Z2.
Cycle parameters:
X, Z: Start point
X1, Z1: Start point contour
X2, Z2: End point contour
P: Feed depth – Maximum infeed depth
H: Contour smoothing
0: With each cut
1: With the last cut
2: No smoothing
I, K: O-size X and Z
A: Start angle (range: 0° <= A < 90°; default: 0°)
W: Final angle (range: 0° <= W < 90°; default: 0°)
R: Rounding
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
B1, B2: -B cham./+B round. (B1 at contour start and B2 at
contour end)
B > 0: Radius of rounding
B < 0: Width of chamfer
BP: Interval time – time span for interruption of the feed
The chip is broken by the (intermittent) interruption of the feed.
BF: Feed period – time interval until the next break
The chip is broken by the (intermittent) interruption of the feed.
G47: Safety clearance
Further information:
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
