Reverse electroplating. Material is removed atom-by-atom via anodic dissolution into a fast-flowing electrolyte solution (like NaCl in water).

This comprehensive guide serves as an updated reference for engineers, students, and professionals looking to build an advanced presentation or presentation slide deck (PPT) on the subject. 1. Introduction to Non-Conventional Machining

Thin or brittle workpieces deform or fracture under standard cutting loads. Key Performance Differences Characteristic Conventional Machining Non-Conventional Machining Mechanism Plastic deformation / Shear Erosion, Melting, Chemical dissolution Tool Material Must be harder than workpiece Can be softer than workpiece Contact Direct physical contact No direct physical contact Tool Wear High mechanical wear Minimal to localized electrical wear Capital Cost Low to medium High initial investment 2. Classification of Advanced Machining Processes Extrusion dies, punch-and-die sets, and intricate gears

: Titanium, stainless steel, granite, and composites.

. These processes have become essential in 2025–2026 for handling extremely hard, brittle, or complex materials used in aerospace, medical, and nuclear industries. Classification of NCM Processes

Non-Conventional Machining (NCM) processes—also known as Advanced Machining Processes (AMP)—solve this challenge. They remove material without direct tool-to-workpiece contact, bypassing the traditional hardness barrier. 1. What is a Non-Conventional Machining Process? This comprehensive guide serves as an updated reference

Combining two or more processes (e.g., Ultrasonic-Assisted EDM or Laser-Assisted Machining) to multiply material removal rates and improve surface quality.

Non-Conventional Machining—also called Advanced Machining—refers to a group of material removal processes that do not use traditional shear-zone cutting tools. Instead, these processes leverage micro-chipping, thermal melting, chemical dissolution, or ionic erosion to achieve precise material removal. Why Do We Need NCM?

Conventional tools cannot cut modern High Strength Temperature Resistant (HSTR) alloys, ceramics, or composites. Complexity:

This process functions as the reverse of electroplating. Material is removed atom-by-atom via anodic dissolution. A high DC current passes through an electrolyte solution flowing between a conductive tool (cathode) and the workpiece (anode).
