2. Macro variable for measurement
An operator needs to set the common data for the measurement to some macro
variables.
2-1. Macro variable for calibration cycles
The following variables are necessary to calibrate a probe equipment. When calibration
cycles are executed, the following macro variables are automatically set. Therefore, in
ordinary case, the operator needs not to set to the following variables. But, depending on
circumstances, a probe might not always need to be calibrated precisely. Instead,
experience value can be used. To calibrate using experience values, the operator needs
to enter the values to the following variables.
Note) If the following data is empty or zero, the alarm is occurred.
#200
: Probe Length
→
Automatically set by G170
The length from the spindle gauge to the top of the stylus
#201
: Stylus Ball Diameter for X axis

Automatically set by G171
#202
: Stylus Ball Diameter for Y axis
