Engineers love data. Include a simple bar chart: Non Conventional Machining Process Ppt

These processes use intense thermal energy to melt and vaporize the workpiece material locally.

A tool shaped to match the desired cavity vibrates at an ultrasonic frequency (typically 20 kHz to 40 kHz) with a low amplitude. An abrasive slurry (usually silicon carbide or boron carbide mixed with water) flows between the tool and the workpiece. The vibrating tool forces the abrasive grains to strike the workpiece surface, eroding material through micro-chipping.

: Material is removed by utilizing electrical, thermal, chemical, or mechanical energy. Hardness Independence Energy Source Material Removal Mechanism Medium / Fluid

Machining turbine blades, barrel rifling, and deburring complex internal intersections. Laser Beam Machining (LBM)

This is the high-retention section of your PPT.

The workpiece and a shaped tool (electrode) are submerged in a dielectric fluid (like kerosene or deionized water). A pulsating DC power supply creates a high voltage difference between them. When the gap becomes small enough, the dielectric breaks down, creating a spark. The spark generates temperatures up to 10,000°C, melting and vaporizing a micro-speck of metal. A tool shaped to match the desired cavity

A great PPT on this subject translates complex physical phenomena (spark erosion, electrochemical reactions, laser optics) into digestible visual logic.

Volumetric material removal is generally much slower than conventional rough milling or turning.

The following table highlights the differences between traditional methods (like LeadRP's list of turning/milling) and non-conventional methods: www.improprecision.com Conventional Machining Non-Conventional Machining Tool Material Must be harder than the workpiece Can be softer than the workpiece Material Removal Direct contact / Chip formation Erosion, melting, or chemical action Energy Source Mechanical (Physical Force) Thermal, Electrical, Chemical, etc. Surface Finish Risk of thermal damage/burrs Generally smoother, stress-free finish Complexity Limited by tool shape/size Can create highly complex geometries Common Industrial Applications

Elias stood in his workshop, staring at a block of super-alloy. His traditional steel drills and tungsten carbide cutters—the workhorses of his 30-year career—lay blunt on the bench. The material was simply too hard, too brittle, and the shapes required were too complex for any physical blade to touch. This is the "Need for Change" .
