7.5.3.13 Measurement of a rectangle (measurement type 25)
Measuring points for determining a rectangle ($AC_MEAS_TYPE = 25)
To determine a rectangle, tool dimensions are required in the following working planes.
● G17 working plane x/y infeed direction z
● G18 working plane z/x infeed direction y
● G19 working plane y/z infeed direction x
Four measuring points are required per rectangle.
Measuring points can be specified in any desired order. The measuring points with the
largest ordinate distance correspond to points P3 and P4.
