SKD11 has been a widely used tool steel for cold works many years while DC53 is intently developed to replace SKD11. In this paper, the machinability of these two steels was compared in terms material removal rate (MRR), electrode wear ratio (EWR), and arithmetic mean value roughness (Ra) specimen machined by electric-discharge machining. The machining variables involved were time peak current....

In this paper, ultrasonic vibration–assisted electrical discharge machining (UEDM) is used to process SiCp/Al composite materials in order achieve a higher material removal rate (MRR) and lower surface roughness, width overcut, relative tool wear (RTWR). On the basis of studying erosion mechanism EDM material, flow field simulation study was carried out using FLUENT software. The results gap sh...

This paper describes an optimum cutting parameters for Titanium Grade5 (Ti-6Al-4V) using Wire-cut Electrical Machining Process (WEDM). The response of Volume Material Removal Rate (MRR) and Surface Roughness (Ra) are considered for improving the machining efficiency. A brass wire of 0.25mm diameter was applied as tool electrode to cut the specimen. The Experimentation has been done by using Tag...

Micro Electric Discharge Machining is a nontraditional machining process which can be used for drilling micro holes in high strength to weight ratio materials. This present research study deals with the single optimization of micro EDM process using Genetic Algorithm. Mathematical models using Response Surface Methodology (RSM) is used to correlate the response and the parameters. The desired r...

The challenge of recent machining industries is reduce lead time and increase production rate in order to maintain their competitiveness. This paper investigates the machinability of mild steel in turning process perform on conventional lathe machine. Twoparameters like tool rake angle and feed are varied to investigate their effect on material removal rate. An attempt has been made to model th...

Electrical Discharge Machine (EDM) parameters have a significant influence on machining characteristic like material removal rate (MMR) and tool wear rate (TWR). Inconel 718, which is widely used in the Medical, Marine, Architectural and food processing industries, is used as a work material. The tool electrode materials used are brass. Experiments are conducted using face centered central comp...
