This paper proposes an evolutional changing method of the machine tool performance adapted for production culture in plastic molding manufacturing. The production culture differs from country/era to country/era. Each production cultural sphere needs each survival processing method in belonging the country or the era. So, every specific manufacturing facility performance is necessary to correspond to the vague production culture. In this research, we identify two types of the production culture, the standard type and the variation type. We attend to the later type, in this paper. Then, we propose the method to turn the ambiguous cultural attribute into the required attribute by using a tree structure and more to estimate relation of the required one and the technical one at the quastified dignity with Quality Function Deployment including Analytic Hierarchy Process. As a result, we can carry out the feasibility study of the evolutional changing method to adapt the machine tool performance even for the variation typed production culture.
