Lifecycle-oriented product modular design of CNC machine tools

Abstract

Product service system is one new production paradigm for manufacturing enterprises to cope with fierce market competition in service economy environment. Product modularization is an important part of product service system development. In this paper, the design process model of product service system is built on the basis of current product service system modeling methods. Guided by lifecycle-oriented modular design idea, the product function is decomposed and the function units are obtained, which correspond to specific parts in the product. Using fuzzy C-means clustering algorithm based on simulated annealing and genetic algorithm for clustering analysis, the division scheme of product modules is got. Lifecycle-oriented product modular design method pays more attention to environmental attributes of the product, and considers the consciousness of environmental protection and sustainability in product design well. Using CNC machine tools as an example, this paper verifies the reliability, rationality and superiority of presented product module division method oriented on CNC machine tools.
