The Computer Aided Design (CAD) has been a very important tool for the design and manufacturing in recent years. However, the CAD has often been used as ‘Computer Aided Drafting’ for engineering parts in industry. The ‘design’ part of the CAD is often not very well implemented and by improving on it we can enhance the usefulness of the computer-based component of the manufacturing process. A ty...

Many manufacturing industries, especially small to medium-sized companies, are in the process of exploring the move from two-dimensional computer-aided design (CAD) technologies to three-dimensional CAD tools interfaced with product data management (PDM) systems. For many companies, their current organizational structure is not well suited to fully leverage the capabilities of new CAD/PDM techn...

Recognition of machining features provides a bridge between Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) of machined parts. CAD produces part descriptions in terms of geometric entities or design features, which need not coincide with the manufacturing features needed by process planning activities. The CAD data must therefore be interpreted so as to generate part represen...

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...

Until recently, the engineering design community has focused on addressing isolated engineering design tasks by developing systems such as computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), or product data management (PDM). Each of these systems has been designed to assist the engineer in a specific task that required little if any cooperation wit...

Fixture design is an important issue in the process of manufacturing. Fixture design is a critical design activity process which bridges Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM). The present paper presents a literature review of the Computer-Aided Fixture Design (CAFD) approaches performed. The purpose of this research is to give a deep and quick understanding of fixtu...

This clinical report describes the complete mouth reconstruction of a patient with a worn dentition. Computer-aided design and computer-aided manufacturing processed porcelain fused-to-zirconia prostheses were used to achieve good esthetics, function, and biomechanics.
