Where, α and β are the linear 4th and 5th axes respectively, each representing any
of U-, V-, and W-axis. If no 4th or 5th axis is specified as the end point command of
the arc, any of the command format is selected among the commands in the XY
plane, ZX plane, and YZ plane.

Note
An arc must be programmed within 360_ range.
The feedrate specified with an F command indicates the tangential velocity in the
three dimensional space constituted by the circular interpolation plane and the
linear axis perpendicular to the interpolation plane.
