If the tool does not wear, an advantage of this method is that the
tool length offset does not have to be adjusted for each new
workpiece because the actual tool length is set as the tool length
offset. If multiple workpieces are cut at one time, the need to
adjust the tool length offset can be eliminated by assigning the
workpiece coordinate system of each workpiece to G54 to G59 and
setting the individual workpiece origin offsets.
