Time Domain Simulation of Turning Operations With Flank Textured Tool
A flank textured cutting tool has been proposed to improve the chatter stability in cutting. Although excellent stability improvement effects have been reported through experimental studies, a simulation method to estimate the effects has not been established so far. In this study, we propose a time-domain simulation method that can take into account the effect of the flank face textures. In order to consider the effect of arbitrary texture geometry on the flank face, the finite element method (FEM) analysis is applied. The relationship between the chatter vibration and the process damping force is modeled, and the process damping coefficients, which represents the process damping effect quantitatively, is obtained. The process damping coefficients are calculated comprehensively by considering the regions where the amplitude and wavelength of chatter vibration can generate. To verify the validity of the proposed method, the face turning experiment was conducted with the prototyped tools consisting of two straight cutting edges. As a result of the verification experiment, it was confirmed that the chatter stability was improved by using a flank-textured tool. The proposed method could demonstrate roughly this chatter stabilization phenomenon.
