In method 2, the reference measurement surface is the origin of
the workpiece coordinate system. The tool tip position of the
reference tool is also the origin of the workpiece coordinate
system. Accordingly, distance L between the tool tip position of
the reference tool and the reference measurement surface is zero.
Therefore, zero is specified in parameter 6024 of distance L. The
actual measurement surface is generally on the same position as
the reference measurement surface, which is the origin of the
workpiece coordinate system. If the measurement surface is set as
the top surface of the reference block or if the top surface of the
workpiece is not set to the origin of the workpiece coordinate
system (for instance, when the origin of the workpiece coordinate
system is shifted from the top surface of the workpiece by a
distance equal to the cutting allowance), the distance between the
reference measurement surface and the actual measurement
surface is separately set as Hm. Then, tool length offset OFSL can
be calculated in the same way as in method 1.
