Abstract

This paper focuses on how basic CIM laboratory work can be enhanced through the use of Internet. In the typical CIM laboratory experiment students are asked to produce their NC-Codes for a given task. By the use of the web-site tools as discussed here, students’ design their parts, produce NC-Codes, upload them to the FTP-Site and prepare necessary configuration for work- order dispatching. In the lab hour they are again asked to send the work order for the part and watch online status and statistics online. This method demonstrates a typical concurrent engineering approach in an automated manufacturing environment, from design to manufacture.

Keywords: CIM Laboratory, concurrent engineering education, and NC-Code generation.

I.Introduction

The manufacturing industry is going through a period of rapid change, accompanied by record growth. To meet the challenge of selling products into a competitive global economy, while continuously reducing costs, manufacturing companies have to increase the efficiency of existing plants. The organizations are increasingly relying on the new generation of hardware and software systems to achieve this elusive goal. Integration is the key to the success of deploying a modern Computer Integrated Manufacturing (CIM) system, which is an ideal state in which computer based manufacturing applications communicate information to coordinate design, planning and manufacturing processes.

Flexible software has become a major goal for developers of manufacturing automation. Flexibility of machine tools and cells has now reached such a level that it is often the inflexibility of the software, not the machines, which inhibits a fast response to market demands [7]. Major categories of viewpoint to manufacturing automation have grown up from the simplest Programmable Logic Controllers (PLC) to the integration of Computer Aided Design (CAD), and Computer Aided Manufacturing (CAM) in modern manufacturing systems, which define the life-cycle of a concurrent engineering approach. Instead of following the conventional, “Proceedings of the 2001 American Society for Engineering Education Annual Conference & Exposition Copyright O 2001, American Society for Engineering Education”
