Classifications and Properties of Materials for Chairside Computer-Aided Design/Computer-Aided Manufacturing Dentistry: A Review

Background and Aim: Chairside computer-aided design/computer-aided manufacturing (CAD/CAM) systems have become considerably more accurate, reliable, efficient, fast, and prevalent since 1985 when CEREC was introduced. The inceptive restorative material option for chairside CAD/CAM restorations was limited to ceramic blocks. Today, restorative material options have been multiplied and include me...

Diffusion Process for GGR Machining System with Spares, Balking and Reneging (RESEARCH NOTE)

This paper deals with the G/G/R machining system consisting of M operating machines as well as S cold standbys. The concepts of balking and reneging are incorporated which make our model more versatile to deal with real time systems. The broken-down machines are sent to repair facilities consisting of R permanent repairmen. The failure times and repair times are generally identical and independ...

A CAD based Computer-Aided Tolerancing Model for Machining Processes

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...
