13.3 TOOL LENGTH/WORKPIECE ORIGIN MEASUREMENT
General
As the functions for measuring the tool length, the following methods
are provided: method by which the tool length is automatically
measured with the program command (G37) (automatic tool length
measurement (See Operator’s Manual (Programming) II-16.5)) and the
method by which the tool length is measured by moving the tool by
manual feed and bringing it into contact with, for example, the top face
of the workpiece (manual tool length measurement (See Operator’s
Manual (Operation II-9.8)). With tool length/workpiece origin
measurement, the operation required for manual tool length
measurement has been simplified, so that machining setup can be
performed easily and in a short time. In addition, the workpiece origin
offset can be measured easily.
- Tool length measurement
When the tool is moved by manual feed so that it contacts the
workpiece or reference block, the tool length compensation can be
measured.
On the tool length compensation measurement screen, manual numeric
commands can be used to specify the T code, M code, and reference
position return commands.
- Workpiece origin measurement
The following workpiece origin offsets can be easily measured: a
workpiece origin offset for the axis in the tool length direction, Z axis,
and workpiece origin offsets for X and Y axes on the plane orthogonal
to the Z axis. Workpiece origin offsets for X and Y axes can be
measured assuming that the workpiece origin is on the workpiece-
mounted surface, or that the workpiece origin is the center of a
machining hole.
Signal
Tool offset measurement mode selection signal GOQSM<G028#7>
[Classification] Input signal
[Function] Selects tool offset value measurement mode.
[Operation] When the signal goes "1" in manual operation mode, tool offset
measurement mode is selected. The screen is automatically replaced
with the tool geometry compensation screen. In the status display field
at the bottom of the screen, "OFST" blinks to indicate that tool offset
measurement mode has been selected.
