Mass finishing processes have widely industrial application, and in most conditions these processes are used with empiricism and trial and error. Based on basic concept of mass finishing, its category is presented. Main aspects of motion and force analysis, material removal model, equipment and consumables, process experiments and industrial application are induced. Finally, development trends are recommended from quantified models, process database, new mass finishing processes and surface integrity. This will provide full investigation and further development and research to improvement part surface integrity.

According to the sharp rheological characteristics of magnetorheological fluid in the magnetic field, the principle and mechanism of magnetorheological finishing is analyzed. Based on the Preston equation, the Reynolds equation and its boundary conditions, the two-dimensional material removal model is built and simulated. Furthermore, a series of MRF experiments are carried out, and the influence of the immersed depth and material kinds on material removal rate are clarified respectively. The experimental results are compared with the modeling results of material removal rate to confirm the mechanistic model validity.

A new plate polishing technique with an instantaneous tiny-grinding wheel cluster based on the magnetorheological (MR) effect is presented in this paper, and some experiments were conducted to prove its effectiveness and applicability. Under certain experimental condition, the material removal rate was improved by a factor of 20.84% as compared with the conventional polishing methods with dissociative abrasive particles, while the surface roughness of the workpiece was not obviously increased. Furthermore, the composite of the MR fluid was optimized to obtain the best polishing performance. On the basis of the experimental results, the material removal model of the new plate polishing technique was presented.

Abstract Contact calculation is of great importance in predicting the material removal (MR) of flexible grinding process (FGP). The contact is mostly considered approximately constant in the existing MR models, while the situations that contact varies a lot after FGP are ignored. Therefore, a novel model is proposed in this paper to take those situations into consideration. Firstly, the nonconstant-contact situation is introduced. Then an equivalent method is developed to convert the nonconstant-contact grinding process into the accumulation of several quasi-constant-contact grinding processes. Based on the equivalent method, a MR model is established, and the procedure to obtain the model parameters by the finite element analysis (FEA) is introduced. In the end, the equivalent method and the MR model are tested by a series experiments of different process parameters. Results show that the proposed MR model can predict the material removal effectively for the nonconstant-contact situations.

Die Werkzeuge beim Gleitschleifen sind wichtige Stellgrößen für den Prozess. Dennoch ist bislang wenig über deren Verschleiß bekannt. Im Fachbeitrag werden Änderungen der Schleifkörperform und -topographie sowie deren Auswirkungen auf die Werkstückrauheit während ihres Einsatzes beschrieben. Es wird geprüft, welche Bedeutung dem Verschleiß beim Gleitschleifen beigemessen werden sollte.   Tools for mass finishing processes (media) are important variables. Nevertheless, little is known about the wear of mass finishing media. In this paper, shape and topography changes of media particles during their use, and their effect on roughness of finished workpieces are investigated. The importance of media wear for mass finishing applications will be examined.

In this paper, Yb:LuScO3 crystal was processed by chemical mechanical polishing (CMP), and the surface roughness of 0.18[Formula: see text]nm was obtained. The atomic step structures of these sesquioxide crystals are successfully characterized by AFM scanning probe technology. Through several CMP experiments, the basic material removal mechanism of a ytterbium-doped LuScO3 crystal during CMP is studied. Based on the findings, a material removal model is established. The results of this study provide ideas for the study of CMP, crystal growth and epitaxy.
