ABSTRACT:
An apparatus and method are disclosed for substantially improving the accuracy and surface finish quality of numerical control machine tool performance by generating velocity command signals for multiple axis drive systems based on the distance between the cutting tool and a point along the desired path, either the desired end point or a dynamic target which moves continuously along the desired cutting path ahead of the cutting tool.
