【Abstract】 An approach of CNC parametric programming based on group technology has been presented. Firstly, the parts with similar machining attributes are grouped in the same part family. Then , an single universal machining program is written for the part family based on the approach of parametric programming. By changing the values of variables in the universal parametric program, the machine controller can implement the cutting for different parts in the same part family. This approach could minimize the number of program changeovers, reduce the redundant codes in the part program, and shorten the length of the program. The efficiency improvement due to application of parametric programming approach based on group technology is 64%-85%.更多还原
