7. Intersection offset for Mixed-type machine
General
When parameter No.19607#4 is set to 1, tool radius compensation for 5 axis
machining can be applied to the mixed type machine whose two rotary axes don't
intersected.
・Parameter example
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 mixed type machine shown below.
Rotary axis B is a tool rotation axis (master) around the Y axis.
Rotary axis A is a table rotation axis (slave) around the X axis.

In the mixed type machine shown above, if the machine coordinate system for rotary
axis B is at 0 degrees, assume:
Rotary table position = (5.0,2.0,-15.0)
Intersection offset vector between the tool axis and tool rotation axis =(3.0,0,2.0)
Tool holder offset value = 2.0
The settings of the parameters for the mixed type machine stated above are as
follows:
