Fuzzy Tolerancing Based on Available Manufacturing Resources

Abstract

Tolerancing is an essential part of the manufacturing process. Previous research on tolerancing is based on process capability and robust design. Few have considered the fuzzy factors in shop floor manufacturing. This paper presents a fuzzy tolerancing method which can ensure the robustness of the design and the fuzziness in manufacturing. First, the fuzziness of the manufacturing is analyzed and a new mathematical model is developed. Then, Simulation Annealing (SA) algorithm is applied to solve the model. An example is included to demonstrate the effectiveness of the new method.
