- When it is exceptional
End position for the arc is not on the arc
If the end of a line leading to an arc is programmed as the end of the arc
by mistake as illustrated below, the system assumes that cutter
compensation has been executed with respect to an imaginary circle
that has the same center as the arc and passes the specified end position.
Based on this assumption, the system creates a vector and carries out
compensation. The resulting tool center path is different from that
created by applying cutter compensation to the programmed path in
which the line leading to the arc is considered straight.
The same description applies to tool movement between two circular
