V: Machining chamfers/roundings at start/end of contour – default: 0
chamfer/rounding is machined:
■ V=0: at beginning and end
■ V=1: at beginning
■ V=2: at end
■ V=3: no machining at start or end
■ V=4: only single chamfers/roundings are machined – not the
base element (requirement: the contour consists of a contour
element)
D: Omit element (influences the machining of undercuts, free
rotations: see table) – default: 0
B: Slide feed for 4-axis machining
■ B=0: Both slides work on the same diameter – at double feed
rate
■ B<>0: Distance from the ”leading” slide (the lead). The slides
work at equal feed rate on different diameters.
■ B<0: The slides with larger number leads
■ B>0: The slide with smaller number leads. Cont

• Cutter radius is compensated
• Offsets (G57/G58): are effective
• On 4-axis cycles, ensure that the tools are
identical (tool type, cutting edge radius,
cutting edge angle, etc.).
