Non Conventional Machining Process Ppt !full! Jun 2026
: These processes use electrical energy to generate a spark or discharge for eroding material.
: Workpieces are extremely hard or brittle (e.g., ceramics, superalloys).

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
Manufacturing complex turbine blades, engine components, and lightweight structural parts.
This comprehensive guide serves as an exhaustive reference blueprint, ideal for engineering students, educators, and professionals looking to build an educational presentation or deep-dive report on this critical manufacturing sector.
No direct contact between the tool and the workpiece (in most cases). : These processes use electrical energy to generate

Workpiece must be electrically conductive; high power consumption. Thermal: Laser Beam Machining (LBM)
Choosing the right non-conventional machining process for industrial manufacturing requires evaluating several core factors: Conventional drilling fails due to tool breakage
Easily shapes materials like tungsten carbide, diamond, titanium, and advanced ceramics.
Non-conventional machining is no longer just a "specialty" field; it is the backbone of high-tech manufacturing. As materials become tougher and components become smaller, these processes are essential for innovation.
This article serves as a comprehensive guide—perfect for those looking to build a —covering the classifications, mechanisms, and advantages of these advanced technologies. 1. What are Non-Conventional Machining Processes?
