CAD/CAM/CNC in Manufacturing - Current Trends in Manufacturing (System) Engineering

Abstract

The Success with the application of CAD/ CAM/ CNC machine tools are at a faster rate. CAD/ CAM in manufacturing system can be obtained to make sure that the machines and people are utilized to the greatest possible extent. This paper not only gives an approach for CAD/ CAM but also show how CNC is incorporated with the manufacturing system. That is CAD/ CAM with the integration of the Computer with the CNC machine tools. Today, manufacturing Sector like Automobile, Railway, Aircraft Component requires accuracy with the application of CAD/CAM must be interfaced to achieve technology-based improvement in manufacturing and to get successive improvements in productivity and quality. CAD/ CAM interface has also been developed for the development of computer Aided process planning (CAPP) and Design for manufacturing and assembly (DFMA) techniques. These techniques allow the manufacturing function to influence the design process and to ensure that designers are aware of the effects of various design features on the ease of manufacture of a part. In this paper, we concentrate on the issues and challenges incurred in the conversion from manual process to CAD/ CAM for quick response to customers by shortening the product cycle. The success of CAD/ CAM/ CNC systems depends upon the total integration of hardware and software functions in the overall information flow. The industrial productivity must be improved and maintained to meet the challenges of global market.
