Calculation of the kinematics dimensions.
Calculation of the coordinates of the A axis.
The drawing shows two different positions that have the same center of the A axis. The
coordinate on the Y axis is parameter TDATA3 and the coordinate on the Z axis Pz. Both
coordinates are necessary to calculate the rest of the parameters.
First position.
1 Position rotary axes A and B at -90º.
2 Make a probing movement along the Y axis at point 1. Jot down the position value
(coordinate) shown at the CNC, appearing in the drawing as ΔY1.
3 Make a probing movement along the Z axis at point 1. Jot down the position value
(coordinate) shown at the CNC, appearing in the drawing as ΔZ1.
Second position.
1 Position the A rotary axis at 90º and the B axis at -90º.
2 Make a probing movement along the Y axis at point 3. Jot down the position value
(coordinate) shown at the CNC, appearing in the drawing as ΔY2.
3 Make a probing movement along the Z axis at point 4. Jot down the position value
(coordinate) shown at the CNC, appearing in the drawing as ΔZ2.
