【正文】 7) The lathe design relationship and geometric position among different parts and ponents。 5) Products’ performance requisition under a special environment。 3) International and domestic standards for related parts and ponent design。 [4] Decisions on which machine to buy or use are usually based on technical specifications. These technical specifications can be measured, yet some important requirements of the machines, such as ease of use, safety, robustness, etc. are not so easily measurable and parable. This paper shows that the Semantic Differential approach may be a tool for measuring perception of those aspects. Lathe design is plicated procession in which lots of knowledge is necessary. The knowledge plays different parts on the different steps of product development. Many new products are developed on the base of existed design knowledge and effects. In lathe design industry, almost 60% of the design works are based on the reuse of existed ponent design and 30% of them are based on the revision of past parts [48]. In this paper we put forward an lathe design technique that adopts NX platform, establishes a special knowledge library of lathe design and merges existed and mature design experience into the design procession of new products with developing tools such as UG/Open API, UIStyler, MenuScript. This new way can effectively provide design quality supports, shorten product design period, improve the design efficiency and level of lathe, and have a significant influence on auto glass industry. II. PREPARE YOUR PAPER BEFORE STYLING 7 The lathe design system applies acquired knowledge to plete rapid design of lathe. The knowledge that is applied in the design system includes mature lathe products, relevant engineering data of lathe design standard, expertise, accumulated design experience and latest research effects. During the product design period, the system is embedded with design reasoning and design course guide mechanism. And designers only need to input parameters demanded by the customers through humanputer interface with the help of guider of design procession. These parameters include lathe thickness, clamp board length, etc. The reasoning machine will pare the facts with the condition part of every rule, if they match well, then the conclusion part of the rule will be added into the design knowledge library as a new fact. According to the demands of the development course, the system is divided into following functional modules. The aim of the development of the system is to realize repaid design of lathe based on knowledge reuse, and improve the design quality and efficiency of the product. The design course of latheinspection gaugeoriented design system can be divided into: requirements analysis phase, preliminary design phase, detailed design phase and function improving and testing phase. During the requirement analysis phase and after careful analysis and conversation, the function of the system is focused on being able to automatically create a set of lathe in accordance with the shape of lathe and clamp board curve set by user and achieving automatic lathe design with standard parts. In terms of choosing development tools, we have considered user’s requirements and proficiency degree toward some tools, and have deci
