Study on the Mechanism and Tool of the Uniform ER Finishing with Changeable Removal Rate Model of Free-Form Surface

Abstract:

At present, the finish machining process of workpiece with free-form surface has the disadvantages of complex trajectory planning, low machining efficiency and precision. To solve these problems, an idea of uniform ER finishing with changeable removal rate model is proposed in this paper. The rheological effect of ER fluid is used to change the magnetic field distribution in finishing areas; then the finishing pressure distribution is changed, that makes the material removal rate of every point in the contact area be approximately equal, so the aim of uniform removal is achieved. In this paper, the quantitative relationship between electric field intensity and finishing pressure is studied. Contrast experiments of finishing and removal effects are performed under the different conditions of electric field distribution. The ER finishing equipment is developed and the proposed finishing method is feasible and has the potential of obtaining the ultra precision.
