Calculation of the kinematics dimensions.
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. Jot down the position value (coordinate) shown at the CNC, appearing in the drawing
as ΔX'.
Third probing move.
With the C rotary axis positioned at 0º and B at 90º, make a probing movement on the second
X side. Jot down the position value (coordinate) shown at the CNC, appearing in the drawing
as ΔX.
Mathematical calculations.
After changing the position with respect to the center of rotation ·1·, the only unknown data
after both probing movements is TDATA6.
