Measuring Cycles for Turning Machines
6.3 CYCLE982 tool: Measure turning and milling tools
Measuring variant
Example:
Axial position,
R ≠ 0,
Measuring without
reversal,
calculate length and
radius,
2 measuring points
necessary
_MVAR=2001
_MA=2
P2 is measured with a
rotated spindle (by 180
degrees), if
measurement is
performed with a
stationary spindle.
Example:
Radial position,
R ≠ 0,
Measurement with
reversal at each
measuring point,
calculate length and
radius,
2 measuring points
necessary (4
measurements)
_MVAR=12101
_MA=1
Example:
Axial position,
R=0,
Measuring without
reversal,
calculate length only
_MVAR=1
_MA=1
