(2) Examples of setting parameters
There are many parameters related to this function.
Therefore, it is recommended that parameters for a target machine be set
based on some examples. Those examples are given below.
<1> Example of setting parameters for a tool rotation type machine
Shown below is an example of setting parameters for a tool rotation type
machine .
Rotation axis C is a tool rotation axis (master) on the Z-axis.
Rotation axis B is a tool rotation axis (slave) on the Y-axis.

Fig. 1.1 (p) Tool rotation type machine example
In the above tool rotation type machine, if rotation axes B and C are at 0
degrees, assume the following:
Tool holder offset value = 2.0
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)
Then, the parameters for the above tool rotation type machine are set as
follows:
