12.5.1 Basic operation
1. Approach movement.
Rapid probe movement (G00) from the cycle calling point to the approach point.
This point is located in front of the point to be measured, at a safety distance (B) from it and along
the probing axis (K).
The approaching movement is made in two stages:
·1· Movement in the main work plane.
·2· Movement along the longitudinal axis.
2. Probing movement.
Movement of the probe along the selected axis (K) at the indicated feedrate (F), until the probe
signal is received.
The maximum distance to be traveled in the probing movement is 2B; if, after travelling that
distance, the CNC does not receive the probe signal, it will display the corresponding error code
and stop the movement of the axes.
Once probing has been made, the CNC will assume as their theoretical position the real position
of the axes when the probe signal is received .
3. Withdrawal movement.
Movement of the probe in rapid (G00) from the point where it probed to the point where the cycle
was called.
The withdrawal movement is made in three stages:
·1· Movement along the probing axis to the approach point.
·2· Movement along the longitudinal axis to the coordinate of the point (along this axis) from
where the cycle was called.
·3· When (C0) is programmed, movement is made in the main work plane to the point where
the cycle is called.
Arithmetic parameters modified by the cycle
Once the cycle has been completed, the CNC will return the real values obtained after
measurement, in the following global arithmetic parameters.
P298 Actual (real) surface coordinate.
P299 Detected error. Difference between the actual surface coordinate and the
programmed theoretical coordinate.
