Presentation Title: Non-Conventional Machining Processes (Updated)
Your search for a "non conventional machining process ppt updated" is timely. The industry has moved beyond "why use NCMP" to "how to optimize NCMP with AI and sustainability."
- EDM/WEDM: Material removal by controlled spark erosion between electrode and workpiece in dielectric fluid. Good for hard, conductive materials; no mechanical force; heat-affected zone and recast layer considerations.
- ECM: Material removed by anodic dissolution in electrolyte; stress-free; good surface finish; requires conductive workpiece; tool wear negligible but process needs handling of electrolytes and hydrogen embrittlement risk.
- LBM/EBM/PAC: Focused thermal energy melts/vaporizes material; high precision (laser), very high energy density (electron beam requires vacuum); heat-affected zones and residual stresses important.
- USM: High-frequency vibration of abrasive-laden tool removes brittle materials; low thermal effects; slow material removal rate.
- AJM/AWJ: High-velocity abrasive particles erode material; cold cutting; suitable for heat-sensitive materials, composites; limited by kerf taper and lower precision (AJM) or high-pressure pump needs (AWJ).
- Chemical milling: Controlled chemical etching removes material; excellent for thin sections, aerospace panels; needs masking and strict chemical control.
- Hybridization: Combining thermal and chemical energy.
- Sustainability: Dry and biodegradable dielectrics.
- Intelligence: Machine learning for parameter optimization.
- Miniaturization: Micro-EDM and FIB for MEMS.
Key Advantage
: High precision and the ability to create complex 3D geometries or micro-holes that standard drills cannot. non conventional machining process ppt updated
