In order to improve the machining productivity of the old NC machine tool and shorten the working hours of a workpiece,a fixed angle tool was made to improve the cutting quantity and increase the cutting speed,and the layered milling method used in the past was changed.The actu-al verification showed that the fixed angle tool improved the machining efficiency of the parts,and the processing time had been reduced by about 54%,which solved the problem of poor machining efficiency of the segment die cavity and reduced the cost of the tool.
