An Efficient CNC Programming Approach Based on Group Technology

Many studies and reports support the significant impact of the application of group technology on various aspects of product design and manufacturing. The fact that group tech­nology is the common solution to similar problems is the main source of such impact. In this paper, one of the less frequent­ly utilized features of GNG technology known as parametric part programming is used to implement the common solution feature of group technology in processing a set of similar parts. Using three part families, the advantages of blending the concept of group technology and parametric programming for CNC machining operations are illustrated. The efficiency improvement due to the use of parametric programming in terms of number of setups and size of program is discussed.
