Slide 2: Introduction

• Conventional machining (lathe, milling, drilling) uses direct contact between tool and workpiece.
• Limitations of conventional methods:
  • Cannot machine extremely hard materials (e.g., titanium, carbides).
  • Causes tool wear, heat generation, and residual stresses.
  • Unable to create complex, intricate shapes (e.g., micro-holes, turbine blades).
• Non-conventional machining uses electrical, chemical, thermal, or optical energy.

Introduction: Why Move Beyond Conventional Machining?

In the world of modern manufacturing, the demand for high-strength, temperature-resistant alloys, complex geometries, and micro-level precision has outpaced the capabilities of traditional machining methods. Lathes, milling machines, and grinders—while effective for common materials—struggle with hardness, intricate cavities, or heat-affected zones.

This is where Non Conventional Machining (NCM) processes, also known as Advanced Machining Processes (AMP) , step in. For educators, students, and industry trainers, creating a high-impact Non Conventional Machining Process PPT is essential to visually and conceptually explain these complex, energy-based material removal techniques.

This article serves as a complete blueprint for building a world-class presentation. We will cover what to include in your slides, the key processes, comparisons, advantages, and the latest trends. Mechanical – USM, AWJM Electrical – EDM, ECG

Part 1: Why a PPT on Non Conventional Machining?

Before diving into the content, we must understand the utility of the medium. A Non Conventional Machining Process PPT is searched for four primary reasons: Slide 11: Advantages & Disadvantages

1. Academic Instruction: Professors need structured slides to teach Mechanical Engineering (B-Tech/Diploma) students.
2. Industrial Training: HR and training managers need to upskill technicians on EDM or Laser cutting.
3. Student Projects: Final-year students require slides for seminar presentations or viva voce.
4. Procurement Decisions: Engineers comparing WJM vs. EDM for a specific job use PPTs for team reviews.

A great PPT on this subject translates complex physical phenomena (spark erosion, electrochemical reactions, laser optics) into digestible visual logic.

Tips for a Great Presentation:

1. Use Visuals: Processes like EDM and ECM are hard to visualize with just text. Use diagrams showing the flow of current, the spark gap, or the fluid flow.
2. Video Clips: If time permits, embed a short 15-second clip of a Water Jet cutting material or a Wire-EDM in action.
3. Real-World Examples: Bring physical samples if possible (e.g., a sheet of metal cut by laser vs. one cut by a saw) to show the edge quality difference.
4. Know Your Audience: If presenting to managers, focus on cost and speed. If presenting to engineers, focus on the mechanism and material properties.

To help you further, I have also included a section below the PPT outline that expands this into a formal paper format (Abstract, Introduction, Body, Conclusion, References) suitable for submission.

Slide 11: Advantages & Disadvantages
