Computer-aided engineering (CAE) is used extensively in the industry to support and enhance the engineering design process. Computer has been used to represent the geometrical parts using computer-aided design (CAD); improved the visualization of the design with virtual reality capability; to produce a rapid prototype for product evaluation purpose; to improve the precision and accuracy with calculation and analysis capability; to propose alternative solutions for decision making purpose, etc. With the computer system, a good engineering design at early stage of manufacturing system is able to reduce the manufacturing cost. Computer software is a valuable and powerful tool to be associated with computer to assist human.
Design for Manufacture and Assembly (DFMA) is a computer technique is used to focus on customer requirements to meet the quality and cost reduction goal. Design for Assemble (DFA) is one of method that used to ensure the right assembly design of a product at the early stage of the manufacturing process. The implementation of DFA in the early stage of product development is support a mechanical design to optimize the design efficiency by reducing the number parts and assembly steps and operation before mechanical product to be assembled. The assembly efficiency will be increased and assembly cost is able to reduce. In this paper, the design and development of the architecture framework of a design for assemble expert system (DAEx) was described.Read More
