Abstract
An ultrasonic vibrator suitable for BT40 taper shank is developed based on theoretical calculation and modal simulation. After calibrating the ultrasonic vibration amplitude under different excitation current, the axial ultrasonic-assisted mill-grinding research of aspheric molds was carried out using YG6X cemented carbide. According to the trajectory of abrasive grits, the linear velocity addition effect of ultrasonic machining on each part of the ball-end grinding wheel is given, and the predictive model of cutting force is built based on the theory of undeformed chip thickness. The ultrasonic-assisted mill-grinding experiments of tungsten carbide molds under different spindle speeds and different vibration amplitudes were carried out, and the edge-chipping, bottom surface contour accuracy and contour roughness were measured. The results show that ultrasonic vibration-assistance can effectively restrain the area of edge-chipping, and the optimization effect improves as the vibration amplitude increases. The ultrasonic vibration can effectively reduce the form error and the roughness of the contour at the bottom of molds.
