Measurement motion
Measurement motion is described below.
<1> A rapid movement is made from the current position to the point
specified by ("CENTER POINT X" + ("OUTSIDE
DIAMETER"/2 + α +r)) in the X-axis direction and by
"CENTER POINT Y" in the Y-axis direction.
<2> In the Z-axis direction, a rapid movement is made to the
approach point ("HEIGHT OF MEAS. PT." + "APROCH
DISTANCE").
<3> In the -Z-axis direction, a movement is made to the position
specified by "HEIGHT OF MEAS. PT." at feedrate fb.
<4> If "ON" is selected for "SPINDLE ORIENTATION", spindle
orientation is performed here.
<5> In the range of (α + γ), a measurement is made at feedrate f.
(First measurement)
<6> Next, a rapid return movement is made by ε, and a rapid return
movement is made in the Z-axis direction to the approach point
("HEIGHT OF MEAS. PT." + "APROCH DISTANCE").
<7> A rapid movement is made to "CENTER POINT X", then a
movement is made in the -X-axis direction by the distance
("OUTSIDE DIAMETER"/2 + α + r) at feedrate fa.
<8> A similar measurement is made in the -X-axis direction and ±Y-
axis directions.
<9> After of the first measurement, a center position for the second
measurement is calculated from the measurement result of each
point.
<10>In the +X-axis direction, a movement is made at feedrate fa to
the position (measurement position of the first measurement + β),
then a measurement is made at the feedrate specified by
"MOVING MEAS. SPEED" in the range from that position to (β
+ γ). (Second measurement)
<11>Next, a rapid return movement is made by ε, then a rapid return
movement is made in the Z-axis direction to the position before
the start of measurement.
<12>A rapid movement is made to the center X coordinate before the
start of measurement, then a similar measurement is made in the
-X-axis direction and ±Y-axis directions.
