The processing of parts with group technology in an individual CNC machining center

摘要

This paper proposes a new machining method for parts using group technology suitable for workshop condition in China. The method divides the parts of each product into similar kinds according to their features, and installs each kind of pants on different working platforms. By changing the platforms in turn, nearly all of the parts of one product can be processed with one CNC machine, and can be sent directly to an assembly shop. Thus the number of management links is reduced and the production rate is increased. This paper presents theoretical analyses of the working platform, coding classification, cluster analysis and fixture planning.
