3. Intersection offset for tool rotation type machine
General
When parameter No.19607#4 is set to 1, tool radius compensation for 5 axis
machining can be applied to the tool rotation 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 tool rotation type machine shown
below.
Rotary axis C is a tool rotation axis (master) around the Z axis.
Rotary axis B is a tool rotation axis (slave) around the Y axis.

In the tool rotation type machine shown above, if the machine coordinate system for
rotary axes B and C is at 0 degrees, assume:
Intersection offset vector between the tool axis and the second rotation axis of the
tool = (5.0,0,3.0)
Intersection offset vector between the second and first rotation axes of the tool
=(3.0,3.0,8.0)
Tool holder offset value = 2.0
The settings of the parameters for the table rotation type machine stated above are
as follows:
