ABSTRACT

CAD/CAM, which embodies the integration of material and information flows, is the key link of
CIMS (computer integrated manufacturing
System). This paper introduces the information technology in CAD/CAM systems and the application of concurrent engineering (CE) philosophy. Based on the NC Manufacturing
Laboratory of the CIMS Research Center of
Tongji University and the CE theory, this paper presents a method of integration of a PC-based
CAD/CAM system, which is mainly accomplished by the integration of software and the development of a serial communication interface based on the existing software, hardware and equipment. The system described is widely suitable for the modern manufacturing enterprise in current scenario.
CAD, CAM, and Finite/Boundary Element
Methods (FEM/BEM) are advanced techniques in geometric design, manufacturing, and numerical simulation. Traditionally, CAD, CAM, and FEM/BEM are often treated as separate modules, which include continuous parametric models and discrete models. Due to the different representations, the post-processing in CAD or the pre-processing in CAM and numerical simulation is essential. The transitions from
CAD to CAM and numerical simulation require substantial effort, and errors are inevitably .introduced. In this paper, a novel framework of realizing the subdivision-based seamless integration of CAD/CAM and numerical simulation was first presented. A unified representation was created with the subdivision
method.
