These processes use high-velocity particles or fluids to erode material mechanically.
Manufacturing demands have shifted dramatically over the last decade. Modern industries regularly utilize extremely hard, brittle, and exotic materials like titanium, composites, and ceramics. Traditional machining methods like turning, milling, and drilling rely on physical tool-to-workpiece contact. These traditional methods fail when processing these advanced materials.
Uses photoresists and etchants to produce intricate flat parts. 2. Deep Dive: Mechanical NCM Processes Ultrasonic Machining (USM)
A tool vibrates at high frequencies (20 kHz to 40 kHz) while an abrasive slurry (boron carbide or silicon carbide mixed with water) flows between the tool and the workpiece. The tool drives the abrasive grains into the surface, causing microscopic chipping.
The Limitations of Conventional Machining (The "Why") non conventional machining process ppt updated
A vibrating tool causes abrasive slurry to strike the workpiece, chipping away material [2].

Integrating these updated trends will make your presentation stand out:
A laser beam is guided inside a water jet filament. The water cools the surrounding zone while the laser cuts, resulting in clean, burr-free cuts in semiconductor wafers. These processes use high-velocity particles or fluids to
are based on the electro-chemical dissolution of material by an electrolyte under the influence of an externally applied electrical potential. The most prominent example is Electrochemical Machining (ECM), which removes material atom by atom through anodic dissolution—making it particularly effective for difficult-to-machine high-strength alloys.
Creating an effective PPT begins with establishing this context. Your opening slides should highlight the core "why": the need to machine complex shapes, achieve high precision, and work with challenging materials that push conventional tools to their limits. The key differentiation points include:
In modern manufacturing, the demand for materials with exceptional properties, such as superalloys, ceramics, and advanced composites, has soared. However, these very materials often possess high strength, hardness, and thermal resistance, making them difficult or impossible to machine using conventional methods. This is where non-conventional machining processes, also known as non-traditional machining (NTM), come into play. NTM processes are defined by their use of mechanical, thermal, electrical, or chemical energy—or a combination of these—to remove material, typically without the use of a sharp, physical cutting tool in the traditional sense.
