Non Conventional Machining Process Ppt -
Non-conventional machining (NCM) processes, also known as advanced or non-traditional machining, utilize mechanical, thermal, electrical, or chemical energy—rather than direct tool-to-workpiece physical contact—to remove material Slideshare . Below is a full review structured for a presentation (PPT) format. 1. Introduction & Need for NCM NCM methods are essential when conventional methods (like milling or turning) are inefficient or impossible Material Hardness : Used for materials harder than 40 HRC, such as titanium, ceramics, and superalloys tirapid.com Geometric Complexity : Capable of producing intricate shapes, micro-holes, and deep cavities Fragile Workpieces : Ideal for slender or flexible parts that cannot withstand the high cutting forces of traditional tools 2.

For a presentation on Non-Conventional Machining (NCM) , you can structure your content into these key sections. NCM refers to material removal processes that use energy sources like thermal, chemical, or electrical power instead of direct physical contact with a sharp tool. Department of Technical Education Training and Skill Development 1. Introduction & Definition Definition : Processes that remove excess material using various techniques involving mechanical, thermal, electrical, or chemical energy without the use of traditional sharp cutting tools. Need for NCM To machine extremely hard or brittle materials (e.g., ceramics, carbides). To create complex shapes that are impossible with traditional tools. To achieve high surface finish and precision. Slideshare 2. Comparison: Conventional vs. Non-Conventional Conventional Machining Non-Conventional Machining Tool Material Must be harder than the workpiece. Tool hardness is not a primary requirement. Tool Contact Direct physical contact with the workpiece. No physical contact; energy is transferred instead. Material Removal Plastic deformation/chipping. Erosion, melting, or chemical dissolution. Noise & Waste High noise and physical scrap. Generally quieter and more precise. 3. Classification of NCM Processes Processes are classified based on the type of energy used to remove material: IIT Kanpur Mechanical Processes : Use mechanical energy (erosion) to remove material. Ultrasonic Machining (USM) : Uses high-frequency vibrations and abrasive slurry. Abrasive Jet Machining (AJM) Water Jet Machining (WJM) Thermal Processes : Use heat to melt or vaporize material. Electrical Discharge Machining (EDM) : Uses spark erosion. Laser Beam Machining (LBM) : Uses a concentrated light beam. Plasma Arc Machining (PAM) Electron Beam Machining (EBM) Chemical & Electrochemical Processes Electrochemical Machining (ECM) : Uses electrolysis. Chemical Machining (CHM) : Uses chemical etching. Slideshare 4. Detailed Example: Ultrasonic Machining (USM) : Employs an ultrasonic transducer and abrasive slurry to achieve intricate shapes.

This paper provides a high-level overview of Non-Traditional Machining (NTM) processes, designed to be easily adaptable for a professional or academic presentation. Advancements in Non-Conventional Machining: A Strategic Overview 1. Introduction Traditional machining relies on physical contact and mechanical force to remove material via chips. However, as the industry shifts toward high-strength, temperature-resistant (HSTR) alloys like titanium and ceramics, conventional tools often fail due to extreme tool wear or inability to achieve complex geometries. Non-conventional machining processes overcome these barriers by utilizing alternative energy sources—thermal, chemical, or electrical—to shape materials without direct physical contact. 2. Classification of Processes Non-conventional processes are primarily categorized by the type of energy used to remove material: Mechanical Processes : Use high-velocity streams of abrasives or fluids (e.g., Ultrasonic Machining (USM) Water Jet Machining (WJM) Abrasive Jet Machining (AJM) Thermal Processes : Use heat to melt or vaporize the workpiece (e.g., Electrical Discharge Machining (EDM) Laser Beam Machining (LBM) Electron Beam Machining (EBM) Chemical & Electrochemical : Utilize controlled chemical erosion or anodic dissolution (e.g., Chemical Machining (CHM) Electrochemical Machining (ECM) non conventional machining processes
