Abstract: On the basis of feature of machined deep hole, an intelligent recognition method is proposed to predict the roundness error of machined hole by using the time-frequency domain information of machining tool cutting vibration. In order to establish the relationship of tool cutting vibration and roundness error, the partitioning problem of the fuzzy input-space of vibration mode is converted into the initial value of input space by introducing the modified fuzzy clustering algorithm into support vector machine, so that the higher accuracy and generalization ability of the proposed method are guaranteed simultaneously. On this basis, a prediction model for roundness error of machined deep-hole is built. A series of experiments were conducted with different cutting parameters and electric currents acting on vibration suppression instrument. The experimental results show that the proposed method is effective and feasible.Key
