PDM (PDM: Product Data Management) is a kind of technology used for managing the product information (including the Component information, Product Configuration, Drawing, CAD document, BOM, Use right etc.) and the relevant procedure of product (including processing define and management).
PDM(PDM: Product Data Management)是一门用来管理所有与产品相关信息(包括零件信息、配置、文档、CAD文件、结构、权限信息等)和所有与产品相关过程(包括过程定义和管理)的技术。
After analyzing the structure-style and design requirements of product-oriented component information in CAPP system, the author studied the management program of product-oriented component information using object-oriented method, realizeda all round dynamic management interface in that case based on Windows graphic technology. The component information management in CAPP system has met the designneeds in explicity, sharing and extensibility.
The function of this system is fulfilled by establishing parts information model based on feature design, and the sharing of parts' information is realized. The CAPP process can directly use the information exported by CAD.
The application datadase is designed by Visual C++6.0, it can fulfil the parts' information coding and output, identifying and output, satisfy the request of the CAPP system getting the information of parts, can offer the information to exploit the CAPP for the creation of the manufaction process and the NC code.
The inversion effect on gaze perception reflects processing of component information
Taken together, these findings indicate that the capacity for parallel transfer of mixture component information is limited in the catfish olfactory system.
Feature-based CAD/CAM integration is a technology used to realise automatic transmission and conversion of component information among CAD, CAPP and CAM applications.
Two types of information are used at this stage, manufacturing process knowledge and component information, including features and associated dimensions, tolerances, surface finish, and material conditions.
All component information becomes available by simply picking the component from the P>amp;ID.
