A design optimization method of machine tools, based on the clarified relationships between evaluative factors of machine-tool dynamics, is proposed. Clarification of competitive and cooperative relationships between characteristics results in division of design variables into three groups. The design variables of each group are determined in each of the multi-phase design optimization procedures. The design decision problem in each procedure is far simpler and easier than that in usual design optimization methods, in which all design variables are determined at the same time. Algorithmic procedures of the design optimization method are described, and effectiveness of the method is demonstrated on a structural model of a milling machine.
