Abstract:

In modern manufacturing engineering, tolerance synthesis is important because it directly affects product quality and manufacturing cost. This paper introduces a new method for tolerance synthesis of machining parts. The new method consists of three steps. First, machining parts are evaluated using the second-order fuzzy comprehensive evaluation. Then, a mathematical model for tolerance allocation is formed based on the machinability of the parts. Finally, the model is solved using the genetic algorithm. The feasibility of the method is validated using a practical gearbox design example.
