Abstract:Reasonable structural parameters of the power tool rest cutter head can effectively solve the contradiction between the locking force of the cutting tools and the inertial of the cutter head dimension. According to the design requirements and characteristics of power tool rest cutter head, and through the determination of the design variables, Objective function and constraint condition of the design of power tool rest cutter head, the structural model of the cutter head is built, structural parameters optimization of the power tool rest cutter head is realized,which attains the expected purpose of making the quality of the power tool rest cutter head lightest,i.e.the volume smallest.Meanwhile the paper discusses the basic thinking and method to use the fmincon function of the optimization toolbox in Matlab software to find the methods of calculation of non-line, single-objective and constrained optimization. To testify the structural parameters optimum design result of the power tool rest cutter head, the static analysis and the dynamic characteristic analysis of the optimized power tool rest cutter head are conducted using the ANSYS software. The simulation results confirmed the rationality of the structure of the cutter head. The optimization result has been applied in practical power tool rest cutter head design and production of Dalian Golden CNC Group CORP.
