Pre-emptied circular pocket.
4.14 Pre-emptied circular pocket.
Geometric parameters:
Xc, Yc Center of the pocket.
R Pocket radius.
r Pre-emptying radius.
Z Part surface coordinate.
Zs Safety plane coordinate.
P Total depth.
Roughing parameters:
Canned cycles (·M· model)
The roughing operation empties the pocket leaving the following finishing stocks. Both stocks
are defined as finishing parameters.
δ Finishing stock on the side walls.
δz Finishing stock at the bottom of the pocket.
The roughing operation defining parameters are:
Δ Maximum milling pass or width.
The cycle recalculates the pass so that all the passes are identical, with the same value as
or smaller than the one programmed. If programmed with a 0 value, it assumes a value of 3/4
of the diameter of the selected tool.
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 pocket is machined 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.
