Basic operation.
7.3 Basic operation.
1 Approach movement (if any of parameters ·XYZ· has been defined).
Movement of the probe at the selected feedrate from the cycle calling point to the first
approach point defined by parameters ·XYZ·.
This approach movement is made in two stages. It first moves in the work plane and then
along the axis perpendicular to the plane.
2 Probing of the first point
The cycle makes a first probing movement, a withdrawal movement and a second probing
move. After the second probing move, the probe withdraws to the approach point.
First probing movement. Probe movement along the selected axis at feedrate ·Fs· until
the probe signal is received.
Withdrawal movement. Return of the probe in rapid (G00) the distance indicated in ·Dr·.
Second probe. Probing movement at feedrate ·F· until the probe signal is received.
Withdrawal movement. Rapid probe movement (G00) from the probing point to the
starting point.
3 If it is a rectangular part, approach movement for calculating the inclination.
Movement parallel to the probed side to touch a different point of the same side.
4 If it is a rectangular part, probing movement to calculate the inclination of the part.
Probing movement at feedrate ·F· until the probe signal is received. The probe returns
to the safety position located at a ·Ds· distance from the part.
5 Approach movement to the second probing point.
Movement of the probe from the first approach point to the second located in front of the
first one.
The perpendicular axis moves the ·Dz· distance up in rapid (G00). Then the probe moves
over the part, at the selected feedrate, to the next approach point. The probe moves a
·Dz· distance back down at feedrate ·Fs·
For the movement, the cycle takes into consideration the dimensions of the part and, if
it is rectangular, its inclination angle. If in this last movement, the probe touches the part,
the CNC shows an error at the cycle parameter value.
6 Probing of the second point.
It is done like the previous one. The probe returns to the safety position located at a ·Ds·
distance from the part.
7 Approach movement to the third probing point.
Movement of the probe from the second approach point to the third.
