Non Conventional Machining Process: Ppt

Non-Conventional Machining (NCM) processes, also known as advanced or non-traditional machining, are specialized manufacturing techniques that remove material using various forms of energy (mechanical, thermal, electrical, or chemical) instead of direct physical contact with a sharp cutting tool . These processes are essential for machining extremely hard or brittle materials and creating complex geometries that traditional methods like milling or turning cannot handle . Classification of NCM Processes

Slide 13: Disadvantages & Limitations

• High initial cost (CNC EDM machine > $50k USD).
• Low Material Removal Rate (compared to conventional turning).
• Special skill required (parameter selection: voltage, frequency, gap).
• Specific issues: Toxic dielectric disposal (EDM), abrasive waste (AWJM).
