TL;DR: In this paper, the effect of magnetic field introduced in the electrode gap in electrolytic grinding was highlighted, when a metal bonded wheel with silicon carbide abrasives was used to face grind tungsten carbide.
Abstract: This paper highlights the effect of magnetic field introduced in the electrode gap in electrolytic grinding, when a metal bonded wheel with silicon carbide abrasives was used to face grind tungsten carbide. The effect of feeding force on metal removal rate and current density is reported. Also the effect on power consumption and specific energy consumption is discussed.

TL;DR: In this article, the results of an experimental study conducted with the objective to understand the mechanism of material removal and the wear behavior of some materials when processed by AFM and magnetically assisted abrasive flow machining are presented.
Abstract: The finish machining of precision components constitutes one of the most challenging and expensive stages in a manufacturing process. Abrasive flow machining (AFM) is a non-traditional machining technique, which is capable of providing excellent surface finish on difficult-to-approach regions on a wide range of components. Not much research work has hitherto been reported regarding process behavior and performance improvement of AFM. This paper reports the results of an experimental study (mixed factorial design) conducted with the objective to understand the mechanism of material removal (MR) and the wear behavior of some materials when processed by AFM and magnetically assisted abrasive flow machining. Scanning electron microscopy (SEM) has been used to gain insight into the underlying wear pattern on the surfaces of different materials. The results suggest that the magnetic field has a strong effect on the MR in AFM. Furthermore, the nature of work material plays an important role in controlling the MR on the surface.

TL;DR: In this article, the role of ECG for machining of composite materials, super alloys and carbides has been summarized and concentrated on the future research possibilities in the same area, and also discussed on mechanism, process, performance parameters and new evolution related to the ECG.
Abstract: The electrochemical grinding (ECG) process is a new noble hybrid machining process comprising electrochemical machining (ECM) and conventional grinding process. ECG process is more significant for machining of composite materials, super alloys and carbides. Even these materials are immensely required in the field of the modern industries and automobile industries for making of precise components with high surface quality. Developed ECG process plays viable improvement in productivity and surface finish with less wheel wear rate as compared to the mechanical grinding. In this article, the role of ECG for machining of aforesaid materials has been summarized and concentrated on the future research possibilities in the same area. It has also been discussed on mechanism, process, performance parameters and new evolution related to the ECG. Moreover, this review article becomes advantageous for researchers to understand the phenomena and new movement of research perceptive and prospective of research development in ECG process.
