Measuring a tool length with stored or current position (measurement type 23)

Tool length with stored / current position
Tool length measurement with stored or current position ($AC_MEAS_TYPE = 23)
In the case of manual measurement, the tool dimensions can be determined in the X and Z
directions. From the known position of the
● Tool carrier reference point and the
● Workpiece dimensions
ShopTurn calculates the tool offset data.
