【正文】 nt process options, one including an additional implantation step that the other one is lacking, the problem is most conveniently modeled by using a very low value for the dose parameter of the implantation step in the flow that, in reality, entirely lacks that step. To realize the general parameterized design of the product, we first need to analyze the product, and determine the interrelation of the ponents, including: lathe design relationship, geometric relationship, and parametric relationship. Next, the relevant engineering knowledge need to be collected, arranged, generalized, abstracted and stored in the forms of data, frame, conditional sentence, and advanced program languages. [1519]. Then, all influential engineering parameters of the product performance need to be defined which may be vague engineering parameters or other type’s orderconfigured auto lathe inspection. Fig. 1 illustrates the different knowledge expression way of the lathe. knowledge of lathe includes: 1) Customer’s personal using requirement to lathe。 2) Customer’s potential demands prediction。 3) International and domestic standards for related parts and ponent design。 4) Previous design case。 5) Products’ performance requisition under a special environment。 6) Design requisition of different parts and ponent。 7) The lathe design relationship and geometric position among different parts and ponents。 8) The characters of parts’ materials and specifications. Through the analysis and research on the basic knowledge of the auto lathe, we have drawn out the main control parameters of the general structure and generalized the rules and facts of 12 the product design knowledge library. m adopts topdown based design method to develop product model. The product structure should be determined before the establishment of product model, so the knowledge that influences product structure should be analyzed and determined. Product structure knowledge mainly includes outshape dimensions, lathe design dimensions and position relationships between different parts and ponents. According to the characters of NX platform, the whole framework knowledge of the product consists of datum plane of product structure knowledge, lathe design restriction among parts, and featurebased ponent arrangement, etc. The control structure of the lathe inspection design is established based on the topology of product sketches on the NX platform. Knowledge of product design process: The knowledge of product design process mainly includes product design flow, appraisement principles, etc. and reflects the interdependence relationship between basic knowledge and product structure knowledge. On the base of the interlinkage of basic knowledge and product structure knowledge, product developing tool UFun is used to achieve product design intelligent navigation and automatic design of variable product structure. B. Automatic design of variable structure As a typical serial transforming product, the structure form of auto lathe changes with requirement change of users. In this paper some advanced techniques are adopted to tackle the variable structure issues, such as the dimensiondriving 13 technique, restrictiondriving technique, geometric objects driving technique and data restraining technique.
