Abstract
In order to study the modular design of computer numerical control machine tools oriented to customer demands, the customer demand information model was established based on rough analytic hierarchy process and information entropy by analyzing and transforming customer demands. Based on the domain mapping method of axiomatic design and quality function deployment integration, the product function model and structure model of computer numerical control machine tools are established. Based on fuzzy clustering analysis, the module division of computer numerical control machine tools is studied, and the dynamic clustering diagram of computer numerical control machine tools is formed with MATLAB as the operating environment. Based on Technique for Order Preference by Similarity to Ideal Solution method, the scheme of computer numerical control machine tools module division is evaluated. Taking the horizontal computer numerical control machine tool products of Shenyang Machine Tool Group as an example, the module division is carried out. The example design and the result analysis prove that the module division system is very effective and fast.
Highlights
Computer numerical control (CNC) machine tools are the key basic equipment of equipment manufacturing industry
With the increasingly fierce market competition, enterprises are in urgent need of rapidly configuring CNC machine tools to meet the diverse needs of customers with lower cost and higher performance.[1]
G Pahl et al.[6] proposed the modular design method to map from the functional domain of a module to the structural domain, and realized the inter-domain
Summary
Computer numerical control (CNC) machine tools are the key basic equipment of equipment manufacturing industry. This article brings forward modular design of CNC machine tools for customer demands. This article puts forward modular design of CNC machine tools for customer demands. It starts from the establishment of customer demand information model. Using the mapping model of integration of axiomatic design (AD) and quality function deployment (QFD), it transforms customer demands into product function model, and establishes product structure model to meet customer demands, so that product module division is more reasonable and can meet customer demands. The model of AD and QFD integration is used to solve the mapping of product from customer demand domain to function domain and function domain to structure domain. Gather the customer demand items obtained in Step D according to the principle of similar meaning and group them again.
