Application of Group Technology in Precision Parts Processing

In the processing of precision parts, as the proportion of traditional single variety mass production methods in manufacturing gradually decreases, multi variety small batch production continues to increase. Under new conditions, how to weave production, improve productivity, reduce costs, and increase benefits through group technology is one of the effective ways to solve the above problems. Group Technology (GT) is not only a method, but also a philosophy of nature and society that can be utilized by the manufacturing industry.

The foundation of group technology in precision component processing is similarity. Similarity refers to the specific properties or features of physical, chemical, geometric, biological functions that exist between systems of different types and levels. The similarity of parts is the foundation of manufacturing technology. Each component has multiple characteristics, such as structure, shape, technical conditions, materials, processes, and production management. Therefore, the similarity of parts is the similarity in determining their features. In addition, there is a correlation between some features, such as the similarity between the geometric shape, structure, and material of the parts and the process similarity.
