Measurement motion
Measurement motion is described below.
- Measurement of the touch sensor position for measurement in the -X-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,Z coordinate) represents
the touch sensor position (Ay,Az).
<2> In the -X -axis direction, a rapid movement is made to the
approach point (X coordinate).
Here, the approach point (X coordinate) represents (touch sensor
position Ax + "CLEARANCE").
<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.
The symbols used above have the following meanings:
A: Touch sensor position. If "SETTIN" is selected in "SPECIFY OF
MEAS. PT.", A represents the "sensor position for measurement
in -X direction" of the specified condition. If "INPUT" is
specified in "SPECIFY OF MEAS. PT.", A represents the
coordinates specified by "MEASURE POINT X", "MEASURE
POINT Y", and "MEASURE POINT Z".
Ax: X coordinate of the touch sensor position above
Ay: Y coordinate of the touch sensor position above
Az: Z coordinate of the touch sensor position above
fa: Value of "FEED-RATE FOR APPROACHING START POINT"
in the measurement condition of the group number specified in
"MEASUREMENT COND."
f: Value of "FEED-RATE FOR 1ST MEASUREMENT" in the
measurement condition of the group number specified in
"MEASUREMENT COND."
