Non Conventional Machining Process Ppt Updated » [ SAFE ]

Easily handles Inconel, Nitralloy, Titanium, and hardened tool steels.

A transducer converts electrical energy into mechanical vibrations (typically 20 kHz to 40 kHz). A horn amplifies these vibrations, forcing abrasive particles (such as boron carbide or silicon carbide) to impact the workpiece surface at high speeds, micro-chipping the material.

: Any electrically conductive material, regardless of hardness.

Chemical (CHM) & Electrochemical Machining (ECM)

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

Spark erosion. The tool and workpiece never touch; a spark gap of is maintained.

High energy consumption and the presence of a distinct Heat-Affected Zone (HAZ) along the cut edge. 4. Chemical and Electrochemical Processes Electrochemical Machining (ECM)

Die sinking, mold making, drilling small holes.

Preheats the material with a laser to reduce its strength before mechanical cutting. Spark erosion

– Presentation Title, Author Name, Date.

These utilize chemical reactions or electrochemical dissolution to remove material.

Need for NCM (Material hardness, precision demands)

The landscape of modern manufacturing has undergone a radical transformation. Traditional machining, once the backbone of industry, now faces limitations when dealing with "super-materials" like Inconel 718, ceramics, and high-entropy alloys. Non-conventional machining (NCM) processes have emerged as the primary solution, utilizing thermal, chemical, electrical, and mechanical energies rather than physical contact with a sharp tool. In 2026, these processes are no longer just "alternatives" but essential components of the advanced manufacturing ecosystem . These processes use mechanical force

These processes use mechanical force, but not via a solid cutting edge. Instead, they utilize high-velocity particles or fluids to erode material.

: Photonic Processes: Laser Beam Machining (LBM Mechanisms).

NCMPs are broadly categorized based on the primary form of energy used to remove material:

Uses ionized gas at extremely high temperatures to cut through thick plates. 3. Comparative Analysis: Conventional vs. Non-Conventional Conventional Non-Conventional Tool Material Must be harder than workpiece Tool hardness is irrelevant Tool Contact Physical contact required Often no physical contact Material Removal Macroscopic chips Atoms or molecules Accuracy Limited by tool vibration Extremely high (micron level) Cost Lower initial setup Higher capital investment 4.
