Diesel engine designers are constantly on the look-out for performance enhancement through efficient control of operating parameters. In this paper, the concept of an intelligent engine control system is proposed that seeks to ensure optimised performance under varying operating conditions. The concept is based on arriving at the optimum engine operating parameters to ensure the desired output in terms of efficiency. In addition, a support vector machines based prediction model has been developed to predict the engine performance under varying operating conditions. Experiments were carried out at varying loads, compression ratios and amounts of exhaust gas re-circulation using a variable compression ratio diesel engine for data acquisition. It was observed that the support vector machines model was able to predict the engine performance accurately.

Several issues including accurate programming, proper tool selection, machining feeds and speeds selection, thermal error compensation, vibration monitoring, etc. contribute significantly to the performance and productivity of a machine tool in an industrial scenario. Only when all these are properly set and controlled it is possible to ensure consistent accuracy and productivity of the machine tool. Significant developments have been made in enhancing the capabilities of a commercial computer numerically controlled (CNC) machine to address this challenge. In this paper, an attempt is made to present the concept of Rapid-Computer Aided Manufacturing (Rapid-CAM) using intelligent automation of a machine tool in order to address the above scenario through a real-time open architecture motion controller as well as to illustrate some of the features that are being implemented in a 3-axis vertical machining centre (VMC). © 2012 The Society of Manufacturing Engineers.
