Relative parameters:
Only rotary axis is specified in the cylindrical interpolation, and it can be a basic axis or an axis
parallel to the basic axis. The axis name of three additional axes are set by NO.225, NO.226, NO.227

Example
：
No. 224 is set to 5, the cylindrical interpolation is executed in G18 plane, and the rotary axis of
the cylindrical interpolation is set to the 5
th
axis (state parameter P187). The axis name of the 5
th
is C
(data parameter No. 225), the axis is one parallel to X axis (NO.230
）
. The radius of the cylinder is
57.299mm, and the developed cylindrical surface is shown below:
