Non-Conventional Machining Processes: The Modern Edge in Manufacturing
The updated PPT is a significant step forward from the previous version, especially with the removal of obsolete content. With the suggested reduction in text density, addition of a process selection matrix, and correction of the electrical conductivity point for EDM, this will become an excellent teaching/training resource.
Conventional tools cannot cut modern High Strength Temperature Resistant (HSTR) alloys, ceramics, or composites. Complexity: non conventional machining process ppt updated
When building your presentation slides, use this structured comparison table to summarize the key performance indicators of each major process: Energy Source Material Removal Mechanism Primary Materials Covered Surface Finish ( Racap R sub a Tool Wear Rate Mechanical Brittle fracture / erosion Glass, Ceramics, Quartz 0.2 – 0.8 AWJM Mechanical Erosion by abrasive impact Metals, Composites, Stone 1.6 – 6.3 Low (Nozzle wear) ECM Electrochemical Ion displacement / Dissolution All conductive metals 0.1 – 0.4 EDM Melting and Vaporization All conductive metals 0.2 – 1.2 LBM Vaporization Metals, Plastics, Ceramics 0.4 – 2.0 CHM Controlled chemical etching Aluminum, Titanium, Steel 1.0 – 4.0 6. PPT Update: Modern 2026 Trends in NCM
An updated PPT must do more than just explain processes; it must contextualize them within the current technological landscape. Complexity: When building your presentation slides, use this
No vacuum required; extremely fast for drilling micro-holes and cutting sheet metal. Electron Beam Machining (EBM)
Micro-electro-mechanical systems (MEMS) and medical implants require completely stress-free, burr-free surfaces without heat-affected zones (HAZ). detailed analysis of key processes
