The conventional CAD/CAM tools are developed to meet the general needs of the market, but not the rapid or specific requirements of the market or customer. Consequently, the companies are looking to customize or tailor the CAD/CAM tools to improve their effectiveness. For this reason, the scope of research in the field of customization of designing tools has improved rapidly in the recent time. This paper discusses an introductory approach for developing an knowledge based system for CAD modelling using customization process of an CAD/CAM tool. The intension behind the development of the system is to reduce the production time and cost. The effectiveness of the proposed system has been examined using an industrial case study. © 2017 Elsevier Ltd. All rights reserved.

Introduction To be in the part of the current volatile economy, the companies are practicing the mass customization strategy. It is believed that, this strategy leads to customer satisfaction, but, in comparison with mass production strategy, it pilots certain assured complexities such as rise of the product cost, requirement of increased expert manpower. The rise of the product cost can decrease the sales of the product due to accessibility of the competitive product to the * Corresponding author. Tel.: +91-9963786665; fax: +91-8772240983.
