In manufacturing process, the quality of final products is significantly affected by both product design and process variables. However, historically tolerance research primarily focused on allocating tolerances based on product design characteristics of each component. This work proposes to expand the current tolerancing practices, and presents a new optimization method of tolerancing mechanical systems using interval computation for the prediction of system response. The proposed methodology is based on the development and integration of three concepts in process optimization: mechanical tolerancing, response surface methodology, and interval computation method. An industry case study is used to illustrate the proposed approach.

The aim of this paper is to provide a general finite element model allowing for the numerical prediction of the extrusion die wear which allows for the evaluation of the die life. A wear prediction model has been implemented in the finite element code Abaqus in which the tool wear is a function of the normal pressure and some material parameters. The tool wear profile is obtained and compared to industrial observations. The proposed approach is expected to the development of methodology for tool cost evaluation due to wear and to the determination the most economic extrusion conditions.
