Measurement motion
Measurement motion is described below.
- Measurement of an offset value in the -X-axis direction
The measurement motion described below is made when [AUTO] is
selected in all input items of “SPECIFY OF X SHIFT”, “SPECIFY
OF Y SHIFT”, and “SPECIFY OF Z SHIFT”.
<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
Z
).
<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
X
).
<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.
