When defining the contours in the surface profile, all these cases follow the sequence
A-B-C-D.
The top left-hand example defines all the depth profiles: Z1(A), Z2(B), Z3(C), Z4(D).
The top right-hand example has left out all the vertical depth profiles: Z1(A), Z3(C).
The lower example is programmed wrong because none of the vertical profiles have
been defined.
If the profile of the island (D) is not defined, the cycle interprets that the island reaches
the surface plane and will machine the island (D').
Roughing parameters:
The roughing operation empties the pocket leaving the finishing stock

on the side walls:
This stock is defined as finishing parameter.
The roughing operation defining parameters are:
Z Part surface coordinate.
Zs Safety plane coordinate.
P Total depth.

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.
I1 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.
