(2) Machine with inclined rotary axis
In the machine explained in this example, the first, second, third, fourth, fifth, and
sixth axes are, respectively, X, Y, Z, A, B, and C.
This is an example of setting parameters for the table rotation type machine shown
below.
Rotary axis B is the table rotary axis (master) on the axis which the axis is inclined at
-45 degrees in the Y-Z plane.
Rotary axis C is the table rotary axis (slave) on the Z-axis.

Table rotation type machine
In the table rotation type machine shown above, if the machine coordinate system for
rotary axes B and C is at 0 degrees, assume:
Rotary table position = (0, 500.0, 0)
Intersection offset vector between the first and second rotary axes of the table = (100,
-100.0, 100.0)
The settings of the parameters for the table rotation type machine stated above are
as follows:
