The growing sophistication of applications continually pushes the design and manufacturing of digital systems to new grades of complexity. Computer aided design education deals with the computer as a tool to help perform the various tasks that comprise the design process of digital systems. In order to understand the capabilities of that tool, one has to study how the tool is used in the differ...

Metal alloys have been used for many years as framework material of dental restorations. The conventional lost-wax and casting method, which was very popular in fabrication metal frameworks, are now being replaced by computer-aided manufacturing technologies. Computer-aided methods offer advantages, such standardization quality manufacturing, precise fit restorations, improved mechanical streng...

The uses of features have been considered to be the technology which bridges the gap between Computer aided design (CAD) and Computer aided manufacturing (CAM) in the CIMS (Computer Integrated manufacturing systems).Active research in the last two decades has resulted in a number of recognition techniques like rule based, graph matching, volume decomposition, hint based, neural network, etc. Th...

Machining features recognition provides the necessary platform for the computer aided process planning (CAPP) and plays a key role in the integration of computer aided design (CAD) and computer aided manufacturing (CAM). This paper presents a new methodology for extracting features from the geometrical data of the CAD Model present in the form of Virtual Reality Modeling Language (VRML) files. ...
