7.5.5 Types of workpiece measurement
7.5.5.1 Measurement of tool lengths (measurement type 10)
Tool length measurement on a reference part that has already been measured ($AC_MEAS_TYPE =
10)
The tool length can be measured on a previously measured reference part.
The plane selection depends on the position of the tool:
● G17 for tool position in the z direction
● G18 for tool position in the y direction
● G19 for tool position in the x direction
