Measurement motion
Measurement motion is described below.
- Measurement of an offset value in the -X-axis direction (measurement of an offset
value in the tool length direction) - When [AUTO] is selected in "SPECIFY OF X, Y,
and Z SHIFT"
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,Z coordinate) represents
the Y and Z coordinates of the "sensor position for measurement
in the -X direction" of the touch sensor position in the specified
measurement condition.
<2> In the -X-axis direction, a rapid movement is made to the
approach point (X coordinate).
Here, the approach point (X coordinate) represents (the 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.
