Non Conventional Machining Process Ppt -

Conventional machining relies on the principle that the cutting tool must be significantly harder than the workpiece (Tool steel: 60-65 HRC; Workpiece: <45 HRC). Modern materials like Inconel 718 (45 HRC), Silicon Carbide (Ceramic, 95 HRC), and CFRP composites cause rapid tool failure. Non-conventional machining bypasses this by using alternative energy forms.

Material is selectively dissolved by controlled chemical etching. Chemical Machining (CHM) / Chemical Milling 3. In-Depth Analysis of Major Processes Mechanical: Ultrasonic Machining (USM)

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.

One of the most common slides in any "Non Conventional Machining Process PPT" is the classification chart. These processes are broadly categorized by the primary source of energy used for material removal. Comparison Table (Conventional vs

As the industry pivots toward eco-friendly initiatives, developing sustainable green dielectrics and dry-EDM technologies will define the next generation of precision engineering.

High setup costs due to the mandatory vacuum chamber environment. 5. Chemical and Electrochemical Machining Processes
