“…These processes are effective, and their implementation is highly flexible for the economical machining or surface finishing of components. Moreover, they can be applied irrespective of part hardness, providing high surface quality and precision without imparting additional residual stresses to the finished surface [ 17 ]. Thus, in magnetic-aided burnishing (MAB), a burnishing force is induced when a strong magnetic field and relative speed are realized between the magnetic burnishing particles (MBPs) and the material surface.…”

Burnishing is an advanced finishing process that produces higher-quality surfaces with better hardness and roughness than conventional finishing processes. Herein, a flexible magnetic burnishing brush comprising stainless steel pins under permanent magnet poles was used to investigate the influence of multiple passes and directions on the produced surface of soft and rough ground prepared brass. In total, five different samples were burnished on each of the two brass samples prepared. Four samples were processed in the same direction for up to four passes and the fifth sample was processed with two passes in the opposite direction. Results indicate that there was approximately a 30% increase in hardness and an 83% increase in microroughness for rougher-surface brass samples. For smoothly prepared surfaces, there was approximately a 14% increase in hardness and a 35% increase in microroughness. In the same direction of multi-pass burnishing, increasing the number of passes negatively affected surface roughness; for rougher surfaces, the surface hardness reduced and process uniformity increased owing to surface over-hardening and flaking mechanisms, and for smoother surfaces, the hardness, roughness, and process non-uniformity increased with the number of passes owing to repeated surface deformation at some locations and high flaking at other locations. Compared to single-pass burnishing, wherein the surface roughness and microhardness showed almost no change with high process uniformity, in burnishing with two opposite-direction passes, the produced surface exhibited better surface roughness, process uniformity, and microhardness improvements owing to a reverse strain mechanism. Hence, opposite burnishing passes are recommended.

Magnetic field assisted powder mixed electrical discharge machining (MFAPM-EDM) process is a hybrid process machining process which improves the machining characteristics and stability of process using assistive magnetic field and dielectric admixed powder. In this article, study on overcut has been performed on MFAPM-EDM machined Aluminium 6061 alloy. Discharge current, powder concentration, pulse on duration, pulse off duration, and magnetic field strength as process parameters have been varied during experimentation. Box Behnken design approach was employed for experimental design to carry out the experiments. Suitable Semi-empirical model was formulated using dimensional analysis for predicting the overcut. The empirical model developed was also compared with RSM model and was found better in predicting the response. Optimum process parameters for minimal overcut was conducted desirability function approach of RSM. Experimental results divulged discharge current as the most important parameters for overcut as compared to other process parameters on account of higher F-value. Confirmatory experiments revealed good correlation between optimum and experimental results.

“…The concept was initially observed by Kravchenko et al 13 The advantages are that the magnetic field is generated within a very short period of time at very low current and it can be operated at room temperature. [14][15][16] It is an environment friendly and low-cost method. 17,18 The magnetic field is produced with electromagnet and permeant magnet.…”

This study examined the effect of magnetic field with single point coated‐carbide tool during turning process of Inconel718 (In718). After the turning process, tribological properties (surface roughness and tool wear) and chip morphology were analyzed. Two cylindrical Neodymium (N52) grade permanent magnets are used to apply the magnetic field during the machining. Cutting speed and magnetic field intensity along with constant feed and depth of cut are used to analyze tribological properties along with chip morphology. Experimental results show that 80 m/min cutting speed and 426 Gauss magnetic field has the best results in term of lowest surface roughness and tool wear. Lorentz forces developed due to the applied external magnetic field help to improve surface roughness compared to nonmagnetic field machining. Developed fine particles during the turning process get repulsed in case of magnetic field machining which helps to improve tool wear.
