“…In low P off, it has greater impact of COF at higher value and in intermittent it tends to decrease and in high P off, it merely shows increased COF value. The regression models of specific wear rate, surface roughness and COF were presented in the equation 2, 3 and 4 respectively [28]. Table VI shows the regression statistics and coefficient of determination values closer to unity holds good reliability, therefore the model can be taken for further analysis.…”

Alloying was conducted on Al 7075 alloy by reinforcement of the metallic portion of molybdenum (Mo) in po wder blended with dielectric fluid to strengthen wear resistance a nd investigate the lubing features of this woven surface. The present work features alloying of Al 7075 with Mo as a vital material. Mechanical attributes along with powder frustration and layered coating size and shape were investigated by scanning electron microscope (SEM), energy dispersive X-ray analysis (EDXA), optical microscope (OM), surface texture with roughness tester and wear vision using pin on disc device. The effect of Peak current (A), Pulse on time (Pon) and Pulse off time (Poff) on the wear execution of an alloyed discharge, Al 7075 auxiliary materials have also been considered using Response Surface Methodology (RSM). Analysis of Variance (ANOVA) was interpreted to add to the effectiveness of material variables on the performance characteristics. Confirmation tests were performed to compare the predicted values with the experimental values and it was found that the results matched well with the experimental results.

One of the non-conventional techniques of metal removal manufacturing processes is electrical discharge machining (EDM). The objective of this paper is to prepare a composite material consisting of a matrix of Aluminium AA 6061 alloy and Boron carbide (B4C) as reinforcement and investigate the output responses, the material removal rate, the quality of the surface formed and overcut during EDM process. The process parameters discharge current, Pulse on time and Duty cycle along with the weight % of B4C are considered for investigation to investigate the output responses such as material removal rate, surface roughness and overcut. From the experimental results, it is observed that the weight % of reinforcement has more influence on the material removal rate. The parameters discharge current and pulse-on-time plays an important role in reducing the surface roughness and overcut. Microstructural study helps in understanding the effect of process parameters on the output responses.

“…Results showed that on-time and current has noteworthy impact on MRR and SR whereas off-time has least influence. Prasanna et al (2017) [48] assessed performance of EDM using Cu electrode and kerosene as dielectric liquid for machining of AA7075 SiC MMC. Principal Component Analysis was used for optimization.…”

Unconventional machining methods are used where conventional techniques are unachievable, inacceptable or cost ineffective. Number of unconventional techniques has been developed to achieve special machining conditions. When these methods are engaged properly, they provide several benefits over conventional methods. High strength alloys can be machined easily, complicated contours and difficult geometries with close tolerances and better surface topograph can be developed using unconventional processes. One of the most popular unconventional machining methods is electrical discharge machining. In this paper, the detailed investigation has carried out to give an insight into the progression of research in the domain of spark machining and optimizing important process variables of this type of machining. It has been found from the available literature that optimization of process parameters of electrical discharge machining can improve machining performance pertaining to material removal and surface finish. Identifying the research gaps and are presented under the heading analysis and discussion. Conclusions drawn from this work will be useful in carrying out research in the sphere of unconventional EDM.
