  1. CNC Programming Circular Interpolation

  2. Circular Interpolation • G02 Clockwise • G03 Counter Clockwise

  3. G02 ClockwiseG02 X__ Y__ I__ J__ F__ • X__ Y__ Is the distance from part zero to the end point of the arc • I__ J__ Is the incremental distance from the start point of the arc to the center point I is relatedto X and J is related to Y • I__ Is an incremental X move • J__ Is an incremental Y move
