Abstract:Studies show that the applied torque and load on the worktable of a dual-turntable five-axis machine tool continuously changes during the machining process. These variations generate vibration in the worktable along the axial direction, thereby reducing the machining accuracy. In order to improve the machining accuracy of the machine tool and the dynamic characteristics of the worktable, this paper first established the nonlinear dynamic equation of the axial vibration of the machine tool table when the workta… Show more
