Abstract:

Tool radius is an important factor affecting machining accuracy. Studying on tool and radius compensation based on milling mache, we put forward a radius compensation algorithm by judging the adapter type of two adjacent curves. The detail and the programming implement of the algorithm are proposed. The experiments result show that the algorithm is suitable for all the radius compensation type, for example adjacent straight line and straight line, straight line and arc, arc and straight line, arc and arc etc,  and the algorithm has small measurement error and high efficiency.

Key words: milling machine, algorithm, adapter type, radius compensation
