Non Conventional Machining Process Ppt Access

Remember the golden rule of NCM: If a milling cutter can't reach it, and a grinding wheel can't grind it, look to a spark, a laser, or a jet of water.

A nickel-based superalloy turbine blade requires 50-80 angled cooling holes (<0.5 mm diameter). Conventional drilling fails due to tool breakage. Laser Beam Machining (LBM) drills holes in 0.2 seconds per hole but leaves a recast layer requiring secondary polishing. EDM provides a cleaner hole but takes 15 seconds per hole. The industry trend is "Laser roughing + ECM finishing." Non Conventional Machining Process Ppt

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. Remember the golden rule of NCM: If a
