Calculation of the kinematics dimensions.
Calculation of parameter TDATA2.
First probing move.
With the C rotary axis positioned at 0º and the B axis at 90º, make a probing movement on
the Z side and preset the position Z = 0.
Second probe.
With the C rotary axis positioned at 0º and the B axis at -90º, make a probing movement on
the Z side. Jot down the position value (coordinate) shown at the CNC, appearing in the
drawing as ΔZ.
Solution.
TDATA1 Known dimension.
TDATA6 Dimensions to calculate.
D Length of the part.
ΔX’ΔX Coordinates shown by the CNC.
L Probe length.
R Probe ball radius.
