11. PROGRAM COMMAND
1441
V: Distance in the Y–axis direction
Specifies the distance from the measurement start point to the
measurement end face in the Y–axis direction.
I: Increment in the X–axis direction
Specifies an increment (distance from measurement point [1] to
measurement point [2]) in the X–axis direction.
J: Increment in the Y–axis direction
Specifies an increment (distance from measurement point [3] to
measurement point [4]) in the Y–axis direction.
F: Movement speed
Specifies the speed at which the probe is to move for measurement.
W:Workpiece coordinate system
Select a workpiece coordinate system to be set up, and enter the
corresponding number listed below:
G54 to G59: 1 = G54, 2 = G55, 3 = G56, 4 = G57, 5 = G58, and
6 = G59
If 48 coordinate systems are valid, the following numbers are specified
to select desired workpiece coordinate systems:
G54.1P1 to P48: 1001 = G54P1, 1002 = G54P2, ..., 1048 =
G54P48
NOTE
Before issuing a command for this cycle, be sure to set the
probe to an approximate measurement start point.
Measurement sequence:
1) The probe moves at the speed fa to a point the distance ”U – a – stylus
ball radius” away from the measurement start point.
2) The probe moves at the speed f in the range ”U + g – stylus ball radius”
until it touches the measurement face (the first measurement session).
3) The probe returns through the distance b at the rapid traverse rate.
4) The probe moves at the specified speed F in the range ”b + g” until it
touches the measurement face (the second measurement session).
5) The probe moves to measurement point [2], [3], and [4] and makes the
same measurement as stated above at each of these measurement
points.
Executing G188 obtains the corner position from measured values, and
outputs the obtained values to the W–specified workpiece zero point
offset value and the following macro variables:
#250: Corner X coordinate (machine coordinate system)
#251: Corner Y coordinate (machine coordinate system)
#252: Corner X coordinate (workpiece coordinate system)
#253: Corner Y coordinate (workpiece coordinate system)
