Powder Mixed Electric Discharge Machining For D2 Steel Process Parameter Optimization A Practical No Nonsense Bachelor Thesis In Mechanical Engineering By Kanwal Singh

Powder Mixed EDM for D2 Steel: Parameter Optimization
✔️ Single 82-page English PMEDM thesis on hard D2 steel

Powder Mixed Electric Discharge Machining (PMEDM) is a non-traditional machining method that uses powdered particles in the dielectric fluid to boost material removal and surface characteristics when machining very hard steels like D2. This 82-page bachelor thesis by Kanwal Singh explores parameter optimization for PMEDM, focusing on pulse-on-time, discharge current, tool material, and grit size, and evaluates responses such as MRR, TWR, surface roughness, and hole diameter variation. The work uses ANOVA in Minitab17 to analyze means and S/N ratios and applies Grey Relational Analysis to optimize multiple outputs simultaneously. SEM analysis provides microstructure insight.

💡 What is powder mixed EDM and why is it handy for hard steels?

• PMEDM injects powder into the dielectric to boost spark energy and debris evacuation, improving material removal and surface finish.
• It’s handy for achieving better control over heat-affected zones and tool wear when machining very hard alloys.
• It supports producing precise features for aerospace components, moulds, and dies that demand consistent microstructure.
