End Point Correction -- Used for handling the last point in a circular motion record if it falls outside of the true arc of the circle. Many toolpath generating systems use an iterative method for producing the toolpath for circular tool motion. In such cases, a record is passed to the postprocessor indicating the following motion records are to be used for machining a radius or circle. If the tolerance band is sufficiently large, it is possible that the last calculated point is outside the calculated arc of the radius or circle. (Intcom 1879)
