16.2 Probe calibration
It is used to calibrate the probe located in the spindle. This probe must
be previously length-calibrated, it will be the one used in measuring-
with-probe canned cycles.
The cycle measures the deviation of the probe ball with respect to the
shaft of the tool holder using a previously machined hole of known
center and dimensions.
Each measuring probe being used will be treated by the CNC like any
other tool. The fields of the tool offsets for each probe will have the
following meaning:
Follow these steps to calibrate it:
1. Once the probe characteristics have been checked, manually
enter the offset for the ball radius value (R).
2. After selecting the relevant tool number and the offset number,
execute the tool length calibration cycle; it will update the "L" value
and initialize the "Off. Z" value to 0.
3. Execution of the probe calibration canned cycle updating the
values of "Off. X" and "Off. Y".
R Probe ball radius. This value must be entered manually in
the table.
L Probe length. This value will be assigned by the tool length
calibration cycle.
Off. X Deviation of the probe ball shaft with respect to the tool
holder along the abscissa axis. This value will be assigned
by this cycle.
Off. Y Deviation of the probe ball shaft with respect to the tool
holder along the ordinate axis. This value will be assigned
by this cycle.
