In order to study the problems existing in the design of wire-cut EDM, reflect the satisfaction of technicians to the design of wire-cut EDM. The evaluation indix is weighted by AHP and entropy method, and a fuzzy evaluation model is built. According to the investigation and expert opinions, an evaluation Index system is established from Physical scale of technicians, safety, function and operation, aesthetics and operator expectation. Through the subjective weight is analyzed by AHP analytic hierarchy process, the objective weight is analyzed by entropy weight method, and the design satisfaction is evaluated by fuzzy comprehensive evaluation method. Based on the needs of machine tool operators, a relatively complete WEDM machine has been designed through analysing the reseach data, AHP-Entropy method retains the objective evaluation of technicians and the subjective judgment of experts, embodies the scientific nature of the combination of subjective and objective weighting, and plays an important role in improving the appearance design of machine tools and providing theoretical basis and quantitative indicators for improving the operation satisfaction of technicians.
