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.

Contour face roughing G820
• 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.).
