Recessing cycle G866
G866 makes a recess defined with G22-Geo
Calculation of the cut segmentation (SBF: see machining parameter 6):
Maximum offset = SBF * cutting edge width
Parameters
NS:
Block number (reference to G22-Geo)
I: Allowance (with precutting) – default: 0
■ I=0: recess is machined in one run
■ I>0: precutting is carried out in the first run; and finishing in the
second
E: Dwell time – no input: corresponds to a spindle revolution
■ With I=0: for each recess
■ With I>0: only during finishing
• Cutter radius compensation: is carried out
• Allowances: are not considered
