The arc end point is sometimes referred to as the target position. \par \par When programming arcs using incremental values (G91), the X and Y values relate to the distance moved along the X and Y axes, from the start point of the arc to the end point of the arc. The sign of the X and Y axis moves (+/-) will depend on the movement of the machine slides in relation to their start position.\cf1\b\fs24 \par \par \par }
