Finishing parameters:
In order to carry out the finishing operation, the roughing must be
defined with tool radius compensation.
This operation removes the finishing stock (δ).
The roughing operation defining parameters are:
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.
δ Finishing stock on the side walls.
When working without tool radius compensation, the stock (δ)
is ignored . In this case, the tool center travel is the same when
roughing as when finishing.
