The CNC PILOT uses the tool definition to distinguish between
external and internal machining.
W Departure angle (reference: Z-axis) – (default: 0°/180°, parallel
to Z-axis)
Q Type of retraction at cycle end (default: 0)
„ Q=0: Returns to starting point (first Z, then X direction)
„ Q=1: Positions in front of the finished contour
„ Q=2: Retracts to safety clearance and stops
V Identifier beginning/end (default: 0)
A chamfer/rounding arc is machined:
„ V=0: At start and end
„ V=1: At start
„ V=2: At end
„ V=3: No machining
„ V=4: Chamfer/rounding arc is machined—not the basic
element (prerequisite: Contour section with one element)
D Omit elements. The following undercuts, relief turns and
recesses are not run (default: 0):
G22 G23
H0 G23
H1 G25
H4 G25
H5/6 G25 H7
to H9

“•”: Do not machine the elements
B Slide lead with 4-axis machining
„ B=0: Both slides work at the same diameter—at double
feed rate
„ B<>0: Distance to the leading slide (the approach). The
slides work on different diameters with the same feed rate.
„ B<0: Slide with larger number leads
„ B>0: Slide with smaller number leads
