Abstract: A new machine tool design method following master?slave relation and constraint relation of machine tool assembly is proposed. The matrix form digitization processing technology is used in the machine tool to perform the matrix transformation for the working precedence of the machine tool′s master?slave assemblies, and drive the assemblies into the working state in accordance with the best cycle. In the process of machine tool manufacturing, the WAVE cutting technology is introduced to realize the seamless linking between the cutter and each assembly of machine tool, and precision cutting, so as to reduce the loss of workpiece material. The whole digital control machine tool system is built in to manage the integral impeller workpiece and impeller electrolytic machining process, and realize the numerical control (NC) machining model with five?coordinate fixed points. The whole process flow is simulated and preset to realize the high?efficient work self?checking and automatic processing programming system, improve the working efficiency and automation degree of machine tool greatly, and reduce the flow error rate and process defective rate.
