Conventional machining relies on the principle that the cutting tool must be significantly harder than the workpiece (Tool steel: 60-65 HRC; Workpiece: <45 HRC). Modern materials like Inconel 718 (45 HRC), Silicon Carbide (Ceramic, 95 HRC), and CFRP composites cause rapid tool failure. Non-conventional machining bypasses this by using alternative energy forms.
Conventional cutting creates high residual stresses, heat-affected zones, and micro-cracks due to intense friction and mechanical forces.
Removes material via controlled, rapid spark discharges between an electrode tool and a conductive workpiece submerged in a dielectric fluid. Non Conventional Machining Process Ppt
Always dedicate a slide to the . Unlike conventional grinding (which may cause burns), EDM and Laser leave a recast layer (white layer) that may contain micro-cracks. ECM and WJM have zero thermal damage , making them superior for critical aerospace parts.
Ideal for exotic, high-strength, and temperature-resistant alloys used in aerospace. Conventional machining relies on the principle that the
A high-speed stream of abrasive particles focused by a nozzle.
By the end of the project, Elias had achieved a level of accuracy and surface finish that his old drills could never match. While these modern methods were slower (lower material removal rate), they made the "impossible" parts for superalloys and carbides possible. Key Takeaways for Your PPT Unlike conventional grinding (which may cause burns), EDM
Zero tool wear; surface finish is excellent and entirely burr-free.
Ultra-high-pressure water (up to 4,000 bar or more) passes through a minute ruby or sapphire orifice to form a supersonic jet. In AWJM, fine abrasive particles (garnet) are introduced into the mixing chamber to cut hard materials.
