Calculation of parameter TDATA6.
First probing move.
With the B and C axes positioned at 0º, make a probing movement on the other X side to
measure the part whose dimension will be the coordinate shown at the CNC minus the
diameter of the probe ball.
Second probe.
With the C rotary axis positioned at 0º and B at -90º, make a probing movement on the first
X side. Take note of the coordinate displayed on the CNC, depicted in the diagram as

X’.
Third probing move.
With the C rotary axis positioned at 0º and B at 90º, make a probing movement on the second
X side. Take note of the coordinate displayed on the CNC, depicted in the diagram as

X.
Mathematical calculations.
After changing the position with respect to the center of rotation ·1·, the only unknown data
after both probing movements is TDATA6.
