Consequently, a new vibration control method was developed in response to both rigid vibrations and vertical elastic vibrations (Fig. 1). The respective vehicle vibrations are controlled by mounting a variable primary vertical damper between the axle box and the bogie frame, and mounting a variable secondary vertical damper between the bogie and the car body.

Most of today's milling machines are fitted with the ball or roller screws, so reverse milling damping is of little significance. No matter it is down milling or up milling, as long as the direction of the milling force is consistent with the clamping direction of the workpiece, it is beneficial to eliminate the vibration of the bending plate parts.
