Roughing parameters:
The roughing operation mills the profile leaving the finishing stock
δ
.
This stock is defined as finishing parameter.
The roughing operation defining parameters are:
Spindle turning direction (icon).
Clockwise with icon
(d)
.
Counterclockwise with icon
(e)
.
Tool radius compensation (icon).
Without compensation
(f)
.
Left-hand compensation
(g)
.
Right-hand compensation
(h)
.
Fz Penetration feedrate.
I Penetration step.
• If programmed with a positive sign (I+), the cycle
recalculates the step so all the penetrations are identical
with the same value as or smaller than the one programmed.
• If programmed with a negative sign (I-), the milling is carried
out with the given pass (step) except the last pass that
machines the rest.
In either case, the cycle limits the step to the cutting length
assigned to the tool in the tool table.
F Surface milling feedrate.
S Spindle speed.
T Roughing tool.
If programmed T=0, there is no roughing.
D Tool offset.
