Abstract:A noncircular curve approximation search algorithm is proposed for processing of the products，which can transform the noncircular curve into a large number of best approximating points.An automatic NC programming system has been developed，which integrates the noncircular curve approximation machining strategy.The NC code can be used in multisystem CNC machine tools，and can improve the efficiency and accuracy of complex products processing.
