Select Hel. slot milling, radial
The cycle mills a helical slot from the Start point thread to the End
point thread. The Start. angle defines the starting position for the
slot. The slot width equals the diameter of the milling cutter.
Cycle parameters:
X, Z: Start point
C: Spindle angle – C-axis position
X1: Thread diameter
C1: Start. angle
Z1: Start point thread
Z2: End point thread
F1: Thread pitch
F1 positive: Right-hand thread
F1 negative: Left-hand thread
U: Thread depth
I: Maximum infeed – The infeed movements are reduced down
to >= 0.5 mm according to the following calculation. Following
that, each infeed movement will amount to 0.5 mm
Infeed 1: I
Infeed n: I * (1 – (n – 1) * E)
E: Cutting depth reduction
P: Run-in lgth – ramp at the beginning of the slot
K: Thread runout length – ramp at the end of the slot
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
D: No.gears
SCK: Safety clearance in infeed direction

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
