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: "Tool change point G14", Page 180
ID : ID no.
S : Cutting speed or Constant speed
F
:
Feed per revolution
D : No.gears
SCK : Safety clearance in infeed direction
