What is the for this presentation (e.g., engineering students, factory machinists, or corporate stakeholders)?
Requires high electrical or thermal energy inputs per unit volume of material removed.
Lower thermal distortion and improved surface integrity.
USM uses a magnetostrictive transducer to convert high-frequency electrical energy (20 kHz) into mechanical vibrations. An abrasive slurry (Boron Carbide or Alumina) is pumped between the vibrating tool and workpiece. The abrasive particles impact the surface, causing micro-cracking and fracture. USM is the only viable method for machining non-conductive, brittle materials like glass, ferrite, and piezo-ceramics. Key drawback: Material Removal Rate (MRR) drops below 2 mm³/min for hard materials.
Zero thermal distortion makes it perfect for heat-sensitive aerospace materials. 4. Thermal Advanced Machining Processes Non Conventional Machining Process Ppt

Die-sinking EDM (for cavities) and Wire EDM (uses a continuous wire to cut profiles).
These processes remove material through the physical erosion caused by a high-velocity stream of abrasives, fluid, or both. Ultrasonic Machining (USM) Abrasive Jet Machining (AJM) Water Jet Machining (WJM) Abrasive Water Jet Machining (AWJM) 2. Electrochemical Processes
Non-conventional machining refers to a group of material removal processes that utilize alternative energy sources instead of traditional sharp cutting tools. These processes do not require the tool material to be harder than the workpiece material, which is a fundamental limitation of conventional machining. Key Characteristics USM is the only viable method for machining
In the realm of manufacturing, machining processes play a vital role in shaping and finishing various materials. Traditional machining processes, such as turning, milling, and drilling, have been widely used for decades. However, with the advent of advanced technologies and the need for precision engineering, non-conventional machining processes have gained significant attention. In this article, we will explore the concept of non-conventional machining processes, their types, and applications, and provide a comprehensive guide for creating a PPT (PowerPoint Presentation) on this topic.
For a presentation on Non-Conventional Machining (NCM) , you can structure your content into these key sections. NCM refers to material removal processes that use energy sources like thermal, chemical, or electrical power instead of direct physical contact with a sharp tool.
Producing micro-holes, deep blind cavities, or intricate profiles is incredibly difficult with physical cutting tools.
