Non Conventional Machining Process Ppt Fix

Essential for micro-machining components used in medical devices and semiconductors.

Weight reduction of aerospace skin panels, printed circuit board (PCB) etching, chemical blanking of thin foils. 6. Process Selection Criteria

: Employs an ultrasonic transducer and abrasive slurry to achieve intricate shapes. Applications

Deburring delicate parts, frosting glass, cleaning electronic components, deflashing molded plastics. Water Jet & Abrasive Water Jet Machining (WJM / AWJM)

Manufacturing surgical instruments, orthopedic implants, and stents using LBM. Automotive: Fuel injection nozzles shaped with micro-EDM. Non Conventional Machining Process Ppt

Comparison Table (Conventional vs. Non-Conventional)

Processes materials with hardness ratings above 400 HB.

Plasma Arc Machining (PAM) offers the highest MRR among thermal processes, while ECM offers the highest among chemical/electrical options. USM and AJM have very low MRR.

Conducting materials are ideal for EDM and ECM. Non-conducting materials (glass, ceramics) require USM, AJM, or LBM. Automotive: Fuel injection nozzles shaped with micro-EDM

USM and ECM provide exceptional surface integrity; PAM leaves a large heat-affected zone requiring secondary finishing.

Developing biodegradable dielectric fluids (like vegetable-based oils) and safer electrolytes to minimize the environmental footprint of these manufacturing units.

: Removes metal via repetitive spark discharges in a dielectric fluid .

Essentially "reverse electroplating." It’s fast and leaves a mirror-like finish without tool wear. C. Chemical Processes Controlled etching using chemical reagents. tell me: For instance

To help refine this presentation material for your exact needs, tell me:

For instance, the slides on highlight its ability to generate complex shapes with high accuracy without any direct contact, making it ideal for machining fragile materials. Its applications include producing dies, glass-making molds, and turbine blades. The EDM section notes that it can machine any electrically conductive material, yet points out challenges like reproducing sharp corners due to "overcut" and electrode wear.

Manufacturing complex turbine blades, engine components, and lightweight structural parts.
