Details:
The arc-cutting program contains four command groups, as showed in the list
below. The combination of these commands determine the arc path of the tool in a
single block.

The end point can be defined either by absolute or incremental coordinates. The
size of the arc can be defined either by the coordinate difference or radius. The arc
cutting direction (CW or CCW) is relative to the center of the arc. Note that the
CW or CCW direction is determined when the tool is at the top (rear) holder. The
direction is reversed when the tool is at the bottom (front) holder.
