Processes are classified based on the type of energy used to remove material: IIT Kanpur Mechanical Processes : Use mechanical energy (erosion) to remove material. Ultrasonic Machining (USM) : Uses high-frequency vibrations and abrasive slurry. Abrasive Jet Machining (AJM) Water Jet Machining (WJM) Thermal Processes : Use heat to melt or vaporize material. Electrical Discharge Machining (EDM) : Uses spark erosion. Laser Beam Machining (LBM) : Uses a concentrated light beam. Plasma Arc Machining (PAM) Electron Beam Machining (EBM) Chemical & Electrochemical Processes Electrochemical Machining (ECM) : Uses electrolysis. Chemical Machining (CHM) : Uses chemical etching. Slideshare 4. Detailed Example: Ultrasonic Machining (USM)
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 Non Conventional Machining Process Ppt
Advanced Manufacturing Techniques for Modern Materials Processes are classified based on the type of
Finally, Elias explored Chemical Machining . Instead of force, he used controlled etching to dissolve unwanted material. This allowed him to create complex patterns on surfaces that a physical tool could never reach. Electrical Discharge Machining (EDM) : Uses spark erosion
These utilize thermal energy to melt or vaporize material. Common examples are Electrical Discharge Machining (EDM) , Laser Beam Machining (LBM), and Electron Beam Machining (EBM).
Non-conventional (or Unconventional) machining refers to a group of processes that remove excess material through various techniques involving mechanical, thermal, electrical, or chemical energy—or a combination of these.
