Introduction

Manufacturers are increasingly automating their production lines with Computer Integrated Manufacturing (CIM) systems in order to stay competitive in the world market. The trend among manufacturers today is to produce smaller batches of more varied products. Without CIM automation, this trend would result in higher costs associated with increased setup time and additional labor. There are, however, many difficulties that manufacturers face in implementing a CIM system. One of these is a shortage of qualified CIM technicians and engineers. Manufacturers have great need for graduates who understand CIM and the integration of all the elements of a CIM system. This need in Southeast Georgia is being addressed by Georgia Southern University (GSU). A course /laboratory in CIM system at GSU provides an industrial- level training in an educational environment.

CIM philosophy has been defined in a variety of ways for decades. It also means different things to different industries [1]. Overall the best definition suggests that a complete CIM system exists when all automated physical activities and automated information processing activities are integrated [2]. Using a network database, a CIM system can manage all manufacturing activities and collect production data that can be used to optimize productivity [3-4]. Although it may not be quite practical or economically feasible for all companies ever fully to achieve a complete CIM system, manufacturers realize that they have to automate in order to achieve a competitive advantage in the global market [5]. The companies that are able to achieve a complete CIM system will benefit significantly in this very competitive world markets [6]. CIM provides many advantages, a few of these are mentioned in the following. Computer integration of information gives all departments of a factory rapid access to the same production data. Accessibility of production data results in faster response to change, which in turn shortens lead times, increases the company’s responsiveness to customer demands, and improves due-date reliability. A computer aided scheduling program helps optimize use of the shop floor, which improves utilization of machine tools and reduces work-in-progress and lead times. Real-time production data can be used to optimize production processes to improve quality, using techniques such as statistical process control. Computer analysis and prediction of material requirements for production can reduce inventory levels and lead times. Integration with suppliers and customers can provide even greater benefits. Downloading machining instructions, including tool changes, from CAM (Computer Aided Manufacturing) systems to CNC (Computer Numerically Controlled) machines reduces machine setup time and increases machine utilization.
