In order to solve the problem of selection of machine tool fixture under the background of green manufacturing, an evaluation and selection method based on comprehensive value was put forward. The evaluation index system of fixture was constructed, the entropy weight method was used to obtain the objective weight of each index,then the objective value of fixture was calculated. According to the expectation and preference of the chooser for each index, the preference compliance degree of fixture was figured out.Then, combining with the specific gravity coefficient,the comprehensive value of fixture was obtained according to the two factors, which could provide reference for the decision-making of the selection party. Finally, a specific example was given to prove the effectiveness of the method.
