Abstract

Aiming at the key scientific and technological problems such as the micro-structured surface (feature size less than 500µm) in the smoothing, the micro-feature structure is easy to be destroyed, the smoothing uniformity is difficult to guarantee, and the material removal rate is low, and a special magnetic shear driven by magnetic force and speed is invented. A new type of intelligent controllable smoothing method and device for the surface of the thickening smoothing medium with fine structure. Through the magnetic field control unit, motion control unit and auxiliary coil control unit of the device, the alternating magnetic field is effectively controlled, and with the adjustment of the spindle speed, the intelligent control of the smoothing force and the motion form and function of the special magnetic shear thickening smoothing medium are realized. range, so as to achieve efficient and flexible finishing of the surface of the fine feature structure. The composition and manufacturing process of a special magnetic shear thickening fairing medium are provided. The invention can avoid the operation space limitation and manufacturing difficulty of the traditional finishing process for finishing the structured fine features of the part, thereby realizing high-efficiency, high-precision and high-quality flexible finishing.
