Description:

This project focuses on development of modeling; analysis and control of dimensional variation in complex multistage assembly processes (MAP) with compliant parts such as in automotive, aerospace, appliance and electronics industries. The goal is to develop a generic MAP model with capabilities to represent key product and process control characteristics/features (KPCs/KCCs) with varying resolution/"information granularity" that can be utilized during design, launch and full production phases of a new manufacturing system. The model will be based on a generic Computer-Aided Design and Manufacturing (CAD/CAM) system integrated with statistical analysis to predict manufacturing process performance in early design phase. A challenge facing the proposed plan is the diversity of required information and lack of physical and geometrical relations between KCC and KPC. The research will focus on developing: (1) variation propagation models integrating statistical and CAD/CAM information; (2) multi-resolution/granularity of KPC/KCC as they change during product development; (3) computational efficiency for simulation of multistage assembly processes; and (4) generic issues pertaining to new process-oriented modeling, design and control. Details in poster1, poster2.
