B-63874EN-1/02 2.MEASUREMENT CYCLE
- 193 -
<7> A similar measurement is made in the -Y-axis direction and ±Z-
axis directions.
<8> After the first measurement, a center position for the second
measurement is calculated from the measurement result of each
point.
<9> In the +Y-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 input feedrate F in the range
from that position to (β + γ). (Second measurement)
<10>A similar measurement is made in the -Y-axis direction and ±Z-
axis directions.
<11>A return movement is made by "APROCH DISTANCE" in the
X-axis direction.
When bit 3 (SHRT) of parameter No. 12380 = 1
<1> The reference workpiece is placed on the table, then this
measurement cycle is executed.
<2> When this measurement cycle is executed, a rapid movement is
first made from the current position to the point specified by
("APROCH CENTER PT.Y" + ("BASE WORK RADIUS D"/2 -
α - stylus radius r)) in the Y-axis direction and by "APROCH
CENTER PT.Z" in the Z-axis direction.
<3> A rapid movement is made in the -X-axis direction to the point
("HEIGHT OF MEAS. PT." + "APROCH DISTANCE").
<4> A movement is made in the -X-axis direction to a point of
"HEIGHT OF MEAS. PT." at feedrate fb.
<5> In the range (α + γ), a movement is made in the +Y-axis
direction at feedrate f. (First measurement)
<6> Next, a rapid return movement is made by β, and a measurement
is made at the feedrate specified by "MOVING MEAS. SPEED"
in the range from that position to (β + γ). (Second measurement)
<7> After a rapid return movement is made by ε, a rapid movement is
made to the Y coordinate specified by "APROCH CENTER
PT.Y", then a movement is made at feedrate fa in the -Y-axis
direction by the distance ("BASE WORK RADIUS D"/2 - α -
stylus radius r).
<8> A similar measurement is made in the -Y-axis direction and ±Z-
axis directions.
<9> A return movement is made by "APROCH DISTANCE" in the
X-axis direction.
The symbols used above have the following meanings:
fa: Value of "FEED-RATE FOR APPROACHING START POINT"
in the measurement condition of the group number specified in
"MEASUREMENT COND."
Rapid traverse rate when bit 2 (RPDF) of parameter No. 12380
is set to 1.
fb: Value of "FEED-RATE FOR APPROACHING START POINT"
in the axis direction in the measurement condition of the group
number specified in "MEASUREMENT COND."
