Abstract

Several factors, such as costs, quality, flexibility and response time, influence the competitive advantages. In the metal working industries, the factors cost and quality are closely linked to the appearance of new materials difficult to machine (whose behaviors are still ignored). As a consequence, the appearance of new and expensive tool materials, together with the demands for high production, varied batches, range of tolerances more and more narrow and low production costs, what have been extrapolating the limits and abilities of operator’s machine. With regards to the factors flexibility and response time, industries have been pointing to a need for reliable information about production performance and about machine-tools technological parameters. Systems of manual appointments are subject to lack of reliability, up date, detection of non conformities and other factors affecting negatively the production system. Additionally, they can generate work redundancy in the acquisition and database feeding. The proposed system contributes to achieve that need using communication and data acquisition technologies, that allows the monitoring and supervision of turning processes. It allows the monitoring of the dimensional quality and indirectly tools wear, as well as sharing shop floor information, in real time, with any place through intranet and/or Internet, aiding the integration of the manufacturing system.
