New vibration-assisted magnetic abrasive polishing (VAMAP) method for microstructured surface finishing

Abstract

In order to polish microstructured surface without deteriorating its profile, we propose a new vibration-assisted magnetic abrasive polishing (VAMAP) method. In this method, magnetic force guarantees that the magnetic abrasives can well contact the microstructured surface and access the corners of microstructures while vibration produces a relative movement between microstructures and magnetic abrasives. As the vibration direction is parallel to the microstructures, the profile of the microstructures will not be deteriorated. The relation between vibration and magnetic force was analyzed and the feasibility of this method was experimentally verified. The results show that after polishing, the surface finish around microstructures was significantly improved while the profile of microstructures was well maintained.

Field-assisted machining of difficult-to-machine materials

“…They applied this method to the finishing of stainless steel and found that the vibration-assisted deburring time was reduced by 40% compared with no vibration, and the initial surface of 2.5 µm Ry pre-polish was improved to 0.45 µm Ry after four passes of polishing. Further, Guo et al [245] proposed a vibration-assisted magnetic abrasive polishing (VAMAP) method, which could polish micro-featured surfaces. The surface roughness Ra increased from 166.9 nm to 25.4 nm and from 2.23 µm to 0.32 µm when the rectangular microstructure and the miniature V-grooves were polished, respectively.…”

Various Non-Conventional Machining methods for Aluminium Metal Matrix Composites

“…were used to analyses the findings. Some Miscellaneous methodologies used such as finite element method, finite volume method and finite difference method to find out new models [2,3,7,11,13,24,30]. So we concluded that most of the researcher have focused on material removal along with some researchers have coted some material with magnetic abrasive particle as wire magnetic and induction free abrasive wire sawing (MIFAWS) is one of the method by which Chunyan Yao et al have prepared magnetic abrasive particle layer on the wire surface and then thickness was calculated for to find out how much magnetic Process was analyzed by MATLAB and results are discussed in detail for developing new areas of research [1].…”

The model used for machining is thermo-physical [24,25,26], electro-mechanical and thermo-electrical [27,28,29,30]. EDM and WEDM process is used for some complicated and tough to machine work pieces and for these machines the numerical model is created to analyses the process parameters for optimization [4,6,14,17], and for semi observational data [19,20].…”

A New Method for V-Groove Microstructured Surface Polishing Using Non-Newtonian Fluids

“…At present, the main way to improve the surface quality after SPDT is polishing [12]. Guo et al proposed a new vibration-assisted magnetic abrasive polishing (VAMAP) method, the quality of the V-groove surfaces after polishing is effectively improved, and the initial tool marks and burrs are removed, but this method is not suitable for magnetic workpiece [13,14].…”
