In 2011, German Govt High Tech Industry 4.0 from a project in strategy Appeared, this is the computerization of production encourages. Indeed, The term "Industry 4.0". This is Hanover Introduced publicly at the fair. same year. Research significance: We are now in the fourth industrial revolution; This is Also referred to as Industry 4.0. Automation and Increasing smart machines and smart Sorting of factories, by data Assorted are highly efficient and Enables productive production of goods across the value chain. Methology: Alternative: Innovation, Technological, Social factors, Flexibility. Evaluation Preference: Equally Important (E), Weakly Important (WI), Strong emphasis (S), very strong emphasis (VS) and absolutely vital (AS). Result: the result it is seen that strongly important (S) is got the first rank where as is the Very strongly important (VS) is having the lowest rank. Conclusion: The value of the dataset for The Era of Industry 4.0 in TOPSIS Method (Similar for the best solution). By option order technique shows its results in strongly important and top ranking. Introduction :We are now in Automation and increasing smart machines and smart Sorting of factories, by data Assorted, more efficient and Enables productive production of goods across the value chain. Industry 4.0 for business owners their Optimize every aspect of operations Empowering to control and understand, and To increase productivity and improve processes, Leverage real-time data to drive growth allows Overall, the Fourth Industrial Revolution is the four major in business Consequences-customer expectations, Product development, collaborative innovation and enterprise Forms.

“…A stirrer was used to ensure the homogeneity of the powder mixed liquid dielectric in a secondary tank. Circular copper rod of 12 mm diameter was used as the tool, since it is a widely used electrode by the researchers in the EDM process (Raj and Prabhu, 2017). Kumar et al (2016a) Six experiments in all were conducted under the machining conditions stated above.…”

Electrical discharge machining (EDM) is used to machine difficult-to-machine materials having high hardness and toughness. One of the recent advancements in the EDM process is the powder mixed electrical discharge machining (PMEDM) process, in which the metallic or abrasive additives in the form of fine powders are added to the dielectric fluid. PMEDM was found to improve machinability in terms of higher material removal rate (MRR) and enhanced tool wear index (TWI), by reducing the breakdown strength of the dielectric. In PMEDM process, machining happens with relatively larger spark gap with enhanced machining characteristics. This paper investigates the influence of powder mixing on the breakdown strength of the liquid dielectric and the gap voltage. Determination of dielectric strength was carried out with a specially designed experimental set-up adhering to ASTM standard D1816 -97. Tests were conducted using silicon carbide, alumina, copper and aluminium powders. The effect of varying the grain size was also studied. An experimental set-up was also designed and realised to measure the influence of powder mixing on the gap voltage and MRR in machining of titanium alloy. The results have shown significant improvement in MRR and TWI.

“…The research results of each optimization problem depend on the input of each type of problem and the optimization method. Some research results have shown that Deng's method can produce higher multiobjective optimization than Topsis [32,33]. Therefore, it is necessary to have studies to determine the optimal results for each specific problem.…”

In machining, the use of appropriate optimization method will significantly contribute in improving the economic and technical efficiency. Currently, there are many techniques used for multi-objective decisions in electrical discharge machining (EDM) and micro-EDM. This may create mistakes in choosing the optimal solution for each problem and mislead the optimum solution. Therefore, it is necessary to have research directions to be able to come up with a reasonable optimal method. In this study, the author has studied multi-targeting decisions in micro-EDM using coated electrode. Experiments were performed using Ti-6Al-4V as a workpiece material and AlCrN coated Tungsten carbide (WC) micro tool electrode. Deng's method was used to decide the optimized level of depth of machining (Z Co-Ordinate) and overcut (OC) in micro-EDM using the coated electrode. Research results are analyzed and evaluated with several other multi-objective decision methods. The results indicated that Deng's method was the suitable method for this study and the machined surface quality of the coated electrode was also analyzed.
