“…The experiments in the studies were carried out adopting a full factorial design (Sivaprakasam et al, 2014;Barman et al, 2017;Alavi, & Jahan, 2017;Ali et al, 2012;Kuriachen, & Mathew, 2016;, Box Behnken design (Kuriachen, & Mathew, 2016;Kuriachen & Mathew, 2015;, central design of experiment ( Sapkal & Jagtap, 2018), rotatable central composite design (Tiwary, Pradhan, & Bhattacharyya, 2014), or orthogonal array design (Krishnaraj, 2016). The machining factors were varied almost in all experiments at three levels.…”

“…In the above studies, ANOVA was used to detect significant input parameters (Kuriachen & Mathew, 2015;Kuriachen & Mathew, 2016;Sapkal & Jagtap, 2018;Alavi &Jahan, 2017;Singh et al,2018). In other studies, researchers continued with developing multi-regression models (Ali et al, 2012;Barman et al, 2017;Plaza et al, 2014;Pradhan & Bhattacharyya, 2008;Kumar &Singh, 2018;Kuriachen & Mathew, 2016;Tiwary et al, 2014).…”

“…Krishnaraj (2016) used an L9 orthogonal array to conduct the experiments and reported that peak current and pulse on time significantly influence and have the maximum percentage contribution to the MRR (50.64%, 35.38% respectively), but for higher values of pulse on time the MRR is slightly affected (Krishnaraj, 2016). Sapkal and Jagtap (2016) reported that a combination of higher level of voltage (150 V) and electrode rotation speed (2500 rpm) and lower level of capacitance (100pF) while pulse on time near to high values (59.1 µs) lead to the best values for taper ratio (0.0179), side gap width (0.0889) and MRR (0.0025 mg/s) in drilling machining process (Sapkal & Jagtap, 2018). Tiwary et al, (2014) by investigating the 3D surface plots found that the MRR gradually increases with the increase in peak current (when peak current is sorted by voltage from low to high values), but it decreases after the middle levels.…”

“…But together with (R 2 ), many more indexes must be investigated in order to assure the reliability of the model: Adj (R 2 ) examines if there are not many predictors in the model, known as overfitting of the model, and consequently is misleading because the additional predictors cause its increase. If Adj (R 2 ) is considerably different from (R 2 ), like the one found by Sapkal and Jagtap (2018), where the two coefficients are (88.39%) and (78.28%), the model must be re-investigated. Predicted (R 2 ) indicates how well a regression model predicts new observations.…”

The micro-Electrical Discharge Machining (micro-EDM) is a non-conventional machining process which utilizes electro-thermal, non-contact effects to remove material from the workpiece. Micro-EDM is controlled by many machining parameters and its accuracy is evaluated by performance measures. It is employed when high accuracy and precision are required, especially when difficult-to-machine materials, like titanium alloy Ti6Al4V, are involved. Given the tremendous applications of Ti6Al4V in biomedical devices, automotive, aerospace and microelectromechanical systems, it is valuable to examine thoroughly the micro-EDM of Ti6Al4V component. This work reports a systematic mapping study of 36 papers published in journals and proceedings of conferences in the nearly two decades 2000-2018. First, we divide the papers into categories according to the various optimization techniques applied for the enhancement of micro-EDM machining process of Ti6Al4V component. Then, we discuss the techniques most used and give insight into the current research trends in micro-EDM. Accompanying comments about the use of the mentioned studies for teaching purposes may be of considerable interest for educators.

The removal of macro-burrs formed after drilling has always been a difficult engineering problem, especially on different-machined materials with through holes. This paper aims at presenting an investigation into hole exit characteristics of Ti6Al4V drilled. Plastic deformation at the end of the cutting process or blanking results into the forming of burr, whose degree of impact is mostly affected by the processing parameters, especially the axial feed. Series experiments were conducted to analysis the effect of processing parameter on formed burr. The volume of burr has great effect on work-piece quality and product cost, the burr height formed easily decreases because great attention from scholars and engineers has been paid to, while the burr width size despised naturally plays a great influence on product quality and machining cost. The new de-burring tool are designed and applied in experiment, the decrease in burr width is obviously found, so the removal of burrs becomes much little than that gotten in traditional tool. The resulting indicates a promising future of de-burring in practical application Journals.
