5.9 CYCLE997 workpiece: Measuring a sphere and ZO determination
Data type Meaning
REAL Velocity for intermediate paths on circular path (G2 or G3)
(for _MVAR=xx11x9, – "Measuring at an angle" only)
0, >0 0: without automatic ZO compensation
>0: with automatic ZO compensation
(Individual values: see Parameter description section "Description of
the most important defining parameters"., Parameter _KNUM)
REAL Starting angle (for _MVAR=xx11x9, – "Measuring at an angle" only)
REAL Stepping angle (for _MVAR=xx11x9, – "Measuring at an angle" only)
REAL Limit value for distortion of triangle (sum of deviations)
ZO is only corrected if the calculated distortion is below this limit
value.
(for _MVAR=x1x1x9 – "Measuring 3 spheres" and _KNUM>0 only)
