2.5.3 Manually measuring the tool
When measuring manually, manually traverse the tool to a known
reference point in order to determine the tool dimensions in the X and
Z directions. ShopTurn then calculates the tool offset data from the
position of the tool-carrier reference point and the reference point.
You can also use the workpiece edge as a reference point or, when
measuring in the Z direction, you can also use the main spindle or
counter-spindle collets.
Specify the position of the workpiece edge during the measurement.
However, you must make the position of the collet known before the
measurement (see Sec. "Spindles").
