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" + ("INSIDE 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) from that point, a measurement is made at
feedrate f. (First measurement)
<6> Then, a rapid return movement is made by β, and a rapid
movement is made to the X coordinate specified by "CENTER
POINT X", then a movement is made in the -X-axis direction by
the distance ("INSIDE DIAMETER"/2 - α -r) at feedrate fa.
<7> A similar measurement is made in the -X-axis direction and ±Y-
axis directions.
<8> After of the first measurement, a center position for the second
measurement is calculated from the measurement result of each
point.
<9> 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)
<10>A similar measurement is made in the -X-axis direction and ±Y-
axis directions.
<11> In the Z-axis direction, a return movement is made by
"APROCH DISTANCE".
When bit 3 (SHRT) of parameter No. 12380 = 1
<1> A rapid movement is made from the current position to the point
specified by ("CENTER POINT X" + ("INSIDE DIAMETER"/2
- α - r)) in the X-axis direction and by "CENTER POINT Y" in
the Y-axis direction.
