Advanced Guide to Non-Conventional Machining Processes (2026 Update) Titanium, Nimonic alloys, and stainless steel

These processes use a high-pressure (up to 600 MPa), high-velocity (up to 900 m/s) jet of water to cut materials. For harder materials, abrasives are added to the jet (AWJM), enabling it to cut through steel, titanium, and composites without generating a heat-affected zone (HAZ)—a critical advantage for heat-sensitive materials.

Uses high-frequency electrical signals converted into mechanical vibrations via a transducer. An abrasive slurry (like boron carbide) flows between the tool and the workpiece, micro-chipping brittle materials.

Micro-holes, deep cavities, and curved internal channels. Slide 1: Title Slide Main Title: Advanced Non-Conventional

Uses strong etchants (chemicals) to remove material from specific areas. 3. Thermal/Electro-Thermal Processes These use intense heat to melt or vaporize the material. Electrical Discharge Machining (EDM): Uses "sparks" to erode the workpiece. Laser Beam Machining (LBM): A highly focused light beam melts the surface. Plasma Arc Machining (PAM): Uses ionized gas at extremely high temperatures. 📊 Comparison Table: Traditional vs. Non-Conventional

: Conventional machining relies on plastic deformation and macroscopic chip formation through physical contact, whereas non-conventional methods often use microscopic erosion or chemical dissolution. 2. Comparison: Conventional vs. Non-Conventional Conventional Machining Non-Conventional Machining Tool Contact Direct physical contact with workpiece No direct physical contact Tool Material Must be harder than the workpiece Tool hardness is often irrelevant Energy Source Primarily mechanical (shear) Electrical, thermal, chemical, or fluid Precision Limited by tool geometry and vibration High accuracy and fine surface finish Material Removal Macroscopic chip formation Microscopic erosion or molecular level 3. Classification of Non-Conventional Processes

Achieve exceptional dimensional accuracy and surface finishes on a microscopic scale.
