Aiming at the metal cutting fluid formulation optimization exist more performance requirements, select dif- ficulty and other issues. Entropy method is used to determine the each performance index weight coefficient, and the metal cutting fluid formulation decision - making model is constructed according to the basic principle of gray situation decision method. Taking the environment - friendly metal cutting fluid formula as an example, the applicability of constructed model in metal cutting fluid formulation optimization is studied. The results show that, the decision model is practicable to using in metal cutting fluid formulation optimization, a scientific, rational and effective decision -making method is provided to obtain a good cost - effective metal cutting fluid formulation, and enrich the formulation technology of domestic metal cut- ting fluid, so it has high applied value.
