3.21 Free profile milling.
The way the roughing and finishing blocks of this cycle are joined will be the one previously
set by the user with the instructions #HSC, G5, G50 or G7. We recommend to use #HSC
or G5 controlling the shape of the corner with the instruction #ROUNDPAR.
Geometric parameters:
Name of the profile.
To machine with tangential entry and exit, define these values inside the profile.
Roughing parameters:
The roughing operation mills the profile leaving the finishing stock

. This stock is defined
as finishing parameter.
The roughing operation defining parameters are:
X, Y Profile entry point
Z Part surface coordinate.
Zs Safety plane coordinate.
P Total depth.
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.
