Currently, many companies are endeavoring in reflecting various demands on their products. By needs for mass-customization, which means low production volume and high varieties in products, have been increased and this led to increase in cost of production. Design for Assembly (DFA) is a methodology which applies concurrent engineering concept to enable reduction in time & cost for product assembly and improvement in assemblability at product design stage. Most of existing DFA tools are implementing checklist system based on surveys on data gathered from users’ experiences at product design stage, and are assessing design under guidelines and calculating DFA indices and Efficiency. However, such methodology increases workloads, difficulties in application to 3D models and difficulties of users who are not familiar with it in understanding and utilizing. Therefore, 3D model-based DFA system, which is applicable to confirmation of assemblability for reflection onto the product design, is designed and implemented. This 3D CAD-based DFA system is expected to decrease workload and help those users who are not proficient assess assemblability more easily at the stage of product design.
