Measuring variant
Example:
Radial position,
R ≠ 0,
Measuring without
reversal,
calculate length and
radius,
2 measuring points
necessary
_MVAR=12001
_MA=1
Notes:
On starting, the measuring point must be outside the measurement cube coordinates in both
coordinates.
On the opposite side of the measuring cube (P2) measurement is performed with a rotated spindle
(by 180 degrees). The same cutting edge is then measured. This only happens if the spindle is
stationary and without reversal.
In this example, L1 refers to the upper cutting edge. If L1 is to be calculated in another measurement,
the starting position must be below the measuring cube.
Example:
Axial position,
R ≠ 0,

P2 is measured with a
rotated spindle (by 180
degrees), if
measurement is
performed with a
stationary spindle.
