The cycle machines the number of recesses defined in Number
of recess cycles Qn. The Start point and End point contour
parameters define the first recess (position, recess depth and
recess width).
Cycle parameters:
X, Z: Start point
X1, Z1: Start point contour
X2, Z2: End point contour
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
A: Start angle (range: 0° <= A < 90°; default: 0°)
W: Final angle (range: 0° <= W < 90°; default: 0°)
R: Rounding
I, K: O-size X and Z
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
P: Cut. width – infeeds <= P (no input: P = 0.8 * cutting width
of the tool)
ET: Recess depth per infeed
EZ: Delay – Dwell time for chip breaking (default: length of time
for two revolutions)
Qn: Number of recess cycles (default: 1)
DX, DZ: Dist.to subsequent recess with respect to the
preceding recess
G47: Safety clearance
Further information: "Safety clearance G47", Page 180
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
