Non Conventional Machining Process Ppt ((exclusive)) Jun 2026

A typical PowerPoint on this topic organizes the many different processes into a clear classification system based on the primary type of energy used for material removal. This is how they are most often grouped:

Conventional cutting creates residual stress, burrs, and thermal distortion.

Finally, Elias explored Chemical Machining . Instead of force, he used controlled etching to dissolve unwanted material. This allowed him to create complex patterns on surfaces that a physical tool could never reach.

Repeatedly remind the audience that because the tool does not physically strike the workpiece in most of these processes, tool wear and structural distortion drop to nearly zero. Non Conventional Machining Process Ppt

A high-velocity stream of gas (air or nitrogen) loaded with fine abrasive particles focuses through a miniature nozzle onto the workpiece to cause micro-abrasive wear.

Can create intricate internal shapes and micro-features that traditional tools cannot reach.

This process uses a tool vibrating at a very high frequency (around 20 kHz) to drive an abrasive slurry against the workpiece. The combined action of the vibration and the abrasive particles chips away tiny fragments of material from the workpiece, which must be hard and brittle (like ceramics or glass). A typical PowerPoint on this topic organizes the

Non-thermal process; leaves no residual stresses or thermal distortion. Electrical Discharge Machining (EDM)

Comprehensive Guide to Non-Conventional Machining Processes Non-conventional machining processes—also known as advanced or unconventional machining—have revolutionized modern manufacturing. Traditional machining methods like turning, milling, and drilling rely on physical contact and a cutting tool that must be harder than the workpiece. However, the advent of exotic, high-strength, and brittle materials requested by aerospace, medical, and electronic industries exposed the limitations of traditional methods.

Highlight real-world engineering environments where these processes are irreplaceable.

Material is removed by a rapid series of recurring electrical spark discharges between a shaped tool (cathode) and a conductive workpiece (anode) immersed in a dielectric fluid (like kerosene or deionized water). The intense heat melts and vaporizes the material.

There are several types of non-conventional machining processes, each with its unique characteristics and applications. Some of the most common types include:

Zero tool wear; leaves a mirror-like surface finish on tough turbine blades. Chemical Machining (CHM)
