Surface modification of tool steel by using EDM green powder metallurgy electrodes

Optimization of Chromium Mixed Powder EDM parameters using Response Surface Methodology for H13 Tool steel Machining

The increasing technological inventions like cellular phones and GPS devices, we observe increasing number of distractions to divert the driver’s attention. This distraction has led to increasing number of accidents on road, which brings a need of a Drowsiness Detection System that calculates various eye parameters to help the driver stay alert. This type of system brings about alertness and ac...

Surface Roughness Evaluation for EDM of En31 with Cu-Cr-Ni Powder Metallurgy Tool

In this study, Electrical Discharge Machining (EDM) is used to modify the surface of high carbon steel En31 with the help of tool electrode (Copper-Chromium-Nickel) manufactured by powder metallurgy (PM) process. The effect of EDM on surface roughness during surface alloying is studied. Taguchi’s Design of experiment (DOE) and L18 orthogonal array is used to find the best level of input paramet...

An Experimental Study of Surface Roughness of H11 Steel in Edm Process Using Copper Tool Electrode

In this study, the effect of input parameters of Electro Discharge Machining (EDM) process including polarity, peak current, pulse on time, duty cycle, gap voltage and concentration of abrasives powder in dielectric fluid on surface roughness are experimentally investigated. A L18 Taguchi’s standard orthogonal array is used for experimental design. Copper is used as tool electrode to machine H1...

Surface Modification of Aluminum by Electrical Discharge Coating with Tungsten and Copper Mixed Powder Green Compact Electrodes

EDM is a prominent non-traditional machining process, which is widely used for machining hard materials which is not possible byconventional processes. A very special aspect of this process is a surface modificationby material transfer from the tool electrode to the work-piece which is commonly known as electro discharge coating (EDC). In this work, electrode prepared with tungsten (W) and copp...
