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.

    CAD/CAM All the engineering functions in design and manufacturing are included in CAD/CAM. During 1970s and early 1980s; CAD/CAM came into the picture. Engineering activities in design include product design, engineering analysis and drafting whereas the process planning and Numerical Machines (NC) part programming come in the manufacturing functions. The literal meaning of CAM is the manufacturing of the products with the aid of computers. Manufacturing is defined as a chain of interrelated activities…

Somewhat similar to the program SolidWORKS, NX allows the user to create sketches of simple and complex objects, and then create a 3-D model of the object. Also, an assembly of these models can be made by assigning constraints to create an overall 3-D assembly model. This…

    CAE stands for Caprine Arthritis Encephalitis. It is a virus that affects goats and not humans. Goats pass CAE to each other via infected colostrum, milk, or blood. It is not passed from feces, breeding, or sharing food and water.(CAE) is a member of the small ruminant lentiviruses which may lead to chronic disease of the joints, and on rare occasions, encephalitis in goat kids less than six months of age. The CAE virus is intimately associated with white blood cells; therefore, any body secretions…
