- Measurement of an offset value in the -Z-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 (X coordinate,Y coordinate).
Here, the approach point (X coordinate) represents (X coordinate
of the "sensor position for measurement in the -Z direction" +
OFS
X
). The approach point (Y coordinate) represents the Y
coordinate of the "sensor position for measurement in the -Z
direction" of the touch sensor position in the specified
measurement condition.
<2> In the Z-axis direction, a rapid movement is made to the
approach point (Z coordinate).
Here, the approach point (Z coordinate) represents (Z coordinate
of the "sensor position for measurement in the -Z direction" of
the touch sensor position in the specified measurement condition
+ "CLEARANCE" + OFS
Z
).
<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 +Z-axis
direction.
