plane formed by a tool direction vector and tool movement direction
intersects a plane perpendicular to the tool axis direction.

1 G41.3 can be specified only in the G00 or G01 mode.
In a block containing G41.3 or G40, only the
addresses D, O, and N can be specified.

must contain a move command. In that block,
however, tool movement in the same direction as the
tool axis direction or the opposite direction cannot be
