11. PROGRAM COMMAND
1423
Data used in common to every measurement cycle must previously be set
in macro variables (common variables).
1. Calibration macro variables
The following macro variables are used to calibrate the probe.
Executing a calibration cycle sets up these variables automatically. If
you do not execute a calibration cycle or do execute a calibration cycle
using empirical compensation data, set up the following macro
variables in advance.
S #200: Probe length → automatically set up with G170.
The probe length is the distance from the gage face on the
tapered section of the spindle to the tip of the stylus.
S #201: Stylus ball diameter in the X–axis direction → automatically
set up with G171.
S #202: Stylus ball diameter in the Y–axis direction → automatically
set up with G171.
S #203: Stylus ball compensation amount in the X–axis direction →
automatically set up with G172 and G173.
S #204: Stylus ball compensation amount in the Y–axis direction →
automatically set up with G172 and G173.
This value is a compensation amount for any displacement
of the stylus center from the spindle center.
NOTE
An alarm is issued if the setting of any of the above macro
variables is null or 0.
2. Measurement cycle macro variables
The following macro variables specify data to be used in
measurement. Be sure to set up these macro variables before using
measurement cycles.
S #210: Measurement speed (f) used in the first measurement session
S #211: Approach distance (a) used in the first measurement session
This macro variable specifies how close the probe is to get
to the measurement face (measured in mm).
S #212: Return distance (b) in the first measurement session
This macro variable specifies the distance (measured in mm)
through which the prove is to return after it touches the
measurement face in the first measurement session. (This
value is used as an approach value in the second session of
measurement.)
S #213: Excess distance (g) in measurement
This macro variable specifies the distance (measured in mm)
through which the probe advances beyond the measurement
face.
S #214: Movement speed (fa) for the probe to get to the measurement
start point
This macro variable specifies the speed at which the probe
moves to get to the measurement start point. (An alarm is
issued if the probe collides with an object like the workpiece
when it is moving toward the measurement start point.)
