Non Conventional Machining Process Ppt Updated New! -

Several high‑quality, recently updated PPT resources are available online:

The updated presentation on Non-Conventional Machining Processes demonstrates a solid effort to modernize the content. The inclusion of recent advancements (e.g., Hybrid machining, EDM with AI integration, Water Jet Guiding Laser) is a strong plus. However, the slide density and lack of comparative data visuals slightly hinder the learning flow.

: High-speed micro-drilling and cutting without any physical tool wear. Chemical & Electrochemical Processes Electrochemical Machining (ECM)

Essentially "reverse electroplating." It dissolves material atom by atom. It results in zero tool wear and a mirror-like finish. C. Chemical Processes non conventional machining process ppt updated

A particularly exciting recent development is , a non‑contact technology that uses a high‑velocity electrolyte jet to remove material locally with exceptional accuracy. ECJM has demonstrated significant advantages, including rapid, non‑thermal, and stress‑free machining capabilities. Variants such as ultrasonic‑assisted, laser‑assisted, abrasive‑assisted, and magnetism‑assisted ECJM are expanding the technology's application potential in semiconductor and biomedical fields, where demand for ultra‑precision components is most pronounced.

NCM processes have scaled down to meet the needs of biomedical and electronics industries. Micro-EDM and Micro-ECM are now standard for producing micro-fluidic channels, coronary stents, and micromechanical sensors (MEMS). Industry 4.0 and AI Integration

Creates a "re-cast layer" and a Heat-Affected Zone (HAZ) that may require post-processing. Crucial for the die and mold-making industry. Laser Beam Machining (LBM) : High-speed micro-drilling and cutting without any physical

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

A key difference is that in non-traditional processes, there is typically , which eliminates the mechanical stresses, tool wear, and heat generation associated with conventional machining. Although some non-traditional processes do involve tool wear, it is rarely a significant problem.

These utilize chemical reactions or electrochemical dissolution to remove material.

Traditional drills cannot create blind, curved microscopic holes or intricate internal slots.

Excellent surface finish, no tool wear, no thermal stress. 4. Latest Trends and Advancements (Updated)
