- Measurement of an offset value in the -X-axis direction (measurement of an offset
value in the tool length direction) - When a soft key other than [AUTO] is selected in
"SPECIFY OF X, Y, and Z SHIFT"
If the Z coordinate of the "sensor position for measurement in the -X
direction" of the touch sensor position is shifted from the Z
coordinate of the tool measurement position as shown below, specify
the shift amount in "SPECIFY OF Z SHIFT".
For example, the motion described below is made when [OFSET+] is
selected in "SPECIFY OF Z SHIFT". (It is assumed that [AUTO] is
selected for the X-axis direction and the Y-axis direction.)
<1> A rapid movement is made from the current position to the
approach point (Y coordinate, Z coordinate).
Here, the approach point (Y coordinate) represents Y coordinate
of the "sensor position for measurement in the -X direction" of
the touch sensor position in the specified measurement condition.
The approach point (Z coordinate) represents the (Z coordinate
of the "sensor position for measurement in the -X direction" of
the touch sensor position in the specified measurement condition
+ OFS
D
).
<2> In the -X-axis direction, a rapid movement is made to the
approach point (X coordinate).
Here, the approach point (X coordinate) represents (X coordinate
of the "sensor position for measurement in the -X direction" of
the touch sensor position in the specified measurement condition
+ "CLEARANCE" + OFS
H
).
<3> In the range from the approach point to ("CLEARANCE" + γ), a
measurement is made at feedrate f. (First measurement)
<4> Next, a rapid return movement is made by β, and a measurement
is made in the range from that position to (β + γ) at the specified
feedrate F. (Second measurement)
<5> Then, a rapid return movement is made by ε in the +X-axis
direction.
