This paper presents techniques of integrating haptic device into computer-aided design and manufacturing. The methodology is proposed as three steps: 1) develop the virtual sculpting system for aiding product design; 2) convert the product design into acceptable form for downstream manufacturing or rapid prototyping; 3) develop multi-axis polyhedral machining planning system with haptic input. ...

This paper discusses the conceptual structure and implementation of an integrated, computer-aided manufacturing system design environment, known as I/O-CAMSD (integrated and open computer-aided manufacturing system design). The work has provided valuable information to prove the feasibility of developing an integrated CAMSD framework to support the complete cycle of manufacturing operation—from...

In 2007 we have computing power and infrastructure that are emarkable in terms of both speed and cost. A casual observer ould expect the effects of this technological “free lunch” on omputer Aided Manufacturing CAM to be an equally dramatic dvance. However it is a measure of this field’s difficulty that very ew of the problems, which invariably involve complex threeimensional geometry, can be s...

This paper describes an expert system that helps designers select a manufacturing process in the early stage of product design. First, the paper focuses on net-shape manufacturing processes and identifies the major factors that affect the selection of an appropriate process. Examples of these factors include shape, production volume, and material. A versatile methodology should consider all the...
