“…Jeykrishnan et al [18] scrutinised the effect of ECM on SKD-12 tool steel using the Taguchi process and reported that MRR can be significantly controlled by the current supplied during machining. A similar result was reported by them while machining AISI D3 steel [19]. Tiwari et al [20] reported that the voltage applied during the ECM of EN 19 steel significantly controlled the overcut.…”

Electrochemical machining (ECM) is a significant technique for getting rid of metal that employs anodic dissolution to get complex contours and deep, precise holes, mostly in the components used in automotive or aerospace sectors. To achieve such high surface characteristics, the selection of factors is important. This work deals with the ECM of AISI 4140 Chromoly steel to investigate the surface roughness and material removal rate (MRR) on the machined specimen using a copper tool electrode. Factors like voltage, signal, and feed rate were optimized by hybrid optimization techniques. To acquire optimal factor configurations, the Taguchi-based WASPAS approach was utilised, accompanied by the Sunflower optimisation methodology. ANOVA was then used to determine the component that was the most impactful factor. A confirmation test is used to signify the outcomes of electrochemical machining. It was revealed that feed rate was among the most significantly relevant factors in affecting surface roughness and MRR. Also, all the optimization approaches provided similar predictions and agreed with the results fetched by the previous research.

In the present work, the preparation of AA-6082/ZrSiO 4 /TiC hybrid composite is studied along with an analysis of the efects of electrochemical machining parameters such as feed rate of electrode (FE), voltage (VO), electrolyte concentration (EL), and electrolyte discharge (ED) rate on the output responses of the material removal rate (MRR) and surface roughness (SR) for Al hybrid composites. Te experiments are carried out based on the Taguchi L16 orthogonal array and the important process parameters are found for MRR and SR. Each parameter contains four diferent levels that are FE (0.10, 0.15, 0.20, and 0.25 mm/ min), VO (10,15,20, and 25 V), EL (15, 20, 25, and 30 g/lit), and ED (1.5, 2, 2.5, and 3 lit/min).Te optimization software, namely, Minitab-17 version helps to fnd the contribution of each parameter on MRR and SR. Te ANOVA result reveals that the feed rate of electrode is the highest contributing parameter, trailed by the electrolyte discharge rate and other process parameters for MRR and SR. A linear model of regression and interaction plots is also included to show the relationship between the parameters. From the observational results, the highest MRR (0.00953 mg/min) is attained by the parameter combination level of the feed rate of electrode of 0.20 mm/min, voltage of 25 V, electrolyte concentration of 20 g/lit, and electrolyte discharge rate of 1.5 g/, whereas the lowest MRR is found at FE of 0.10 mm/min, VO of 10 V EL-15 g/lit and ED of 2.5 g/litre.

For SR, the maximum and minimum are recognized at FE2-VO4-EL3-ED2 (0.15 mm/min, 25 V, 25 g/lit, and 2 lit/min) and FE1-VO1-EL1-ED1 (0.10 mm/min, 10 V, 15 g/lit, and 1.5 lit/min), respectively. Finally, the increment of MRR and SR values is mostly dependent on the feed rate of the electrode.

Equiatomic nickel-titanium (NiTi) composed of Nickel and Titanium (i.e. 50:50% of Ni and Ti) or Nitinol, an expensive, very smart shape memory alloy material of choice for biomedical applications because of its bio compatibility. Machining Nitinol is challenging by means of non-traditional techniques. Experiments are carried out to produce a precise geometrical micro hole in Shape memory alloy Nitinol, using Electrochemical Micromachining (Abbreviated as ECMM). In ECMM process, micro holes are produced with 500 μm tool electrode in a shape memory alloy (SMA)-Nitinol of 0.25 mm thickness using the Non-passivating electrolyte (NPE), Passivating electrolyte (PE) and the Composite electrolyte (CPE) to study the machining characteristics. A tedious effort is made to produce such a micro hole using a noval mixed electrolyte to improve machining process. Polarization studies are also carried out for all the chosen electrolytes. The process is clearly analyzed thoroughly with the help of polarization and SEM. Expected results with good precision and surface characteristics are obtained when the nitinol is machined with the composite electrolyte. The results proved that the compatibility of machining nitinol is composite type of electrolyte. Composite electrolyte provides the combined advantages of both the passivated and non-passivated electrolytes. This study resulted in finding the suitable and optimized parameters for machining Nitinol with PE, NPE and CPE with better precision and good surface integrity.
