Die-Sinking EDM: Uses a shaped tool to sink a cavity into the workpiece.

2026 Advanced Trends (Hybrid systems, Green Dielectrics)

Introduces ultrasonic vibrations to the EDM electrode to improve dielectric flushing, reducing cycle times by up to 50%. Micromachining and Nanotechnology

Provide tailored for specific processes like EDM or ECM.

In AJM, a high-velocity stream of gas (air or nitrogen) carries fine abrasive particles to erode the workpiece surface through impact. It is a versatile process used for cutting, deburring, cleaning, and etching operations, particularly on hard and brittle materials. non conventional machining process ppt updated

A highly concentrated, coherent, monochromatic light beam is focused onto the workpiece. The extreme energy density instantly melts and vaporizes the material.

An updated PPT must do more than just explain processes; it must contextualize them within the current technological landscape.

Utilizes a concentrated light beam to melt/vaporize material [6].

ECM is often described as the reverse of electroplating. Material is removed atom by atom via anodic dissolution. Die-Sinking EDM: Uses a shaped tool to sink

Reduces tool wear and workpiece damage.

Advanced AWJM systems now incorporate closed-loop recycling systems to separate, wash, and reuse garnet abrasives up to three times, drastically lowering waste output.

Piezoelectric transducer, concentrator/horn, tool, and abrasive delivery system.

Are there specific you would like to expand on? In AJM, a high-velocity stream of gas (air

Non-conventional machining processes do not use conventional cutting tools (like drills or lathe bits) for material removal. Instead, they utilize direct energy sources—mechanical, thermal, chemical, or electrical—to remove material at the atomic or molecular level.

Mechanical Advanced Processes

Delicate structures like semiconductor wafers deform under the physical force of traditional cutting tools. Classification of Non-Conventional Machining Processes

Non-conventional machining processes (NCMP) solve this problem. These processes use thermal, chemical, electrical, or mechanical energy instead of direct tool-to-workpiece contact. This article provides a comprehensive overview of modern NCMP, optimized for engineering presentations and technical slides. 1. Introduction to Non-Conventional Machining
