Moving beyond basic workshop knowledge, it explores the underlying principles of plastic deformation, chip formation, cutting mechanics, and tool performance. Whether you're in mechanical, production, metallurgy, or aerospace engineering, this course equips you with the knowledge to optimize processes, enhance efficiency, and innovate in manufacturing.

Learn from an Eminent Instructor: Prof. Sounak Kumar Choudhury

The course is led by Prof. Sounak Kumar Choudhury of the Indian Institute of Technology (IIT) Kanpur. With a Ph.D. in Mechanical Engineering and extensive post-doctoral research from Moscow, Russia, Prof. Choudhury brings over three decades of dedicated teaching and research experience to the table. His specialized expertise in conventional/non-conventional machining, automatic control, and manufacturing automation ensures that the curriculum is both deep-rooted in theory and relevant to modern industrial challenges.

Detailed Course Curriculum: A Structured 4-Week Journey

The course is systematically laid out over four weeks, progressing from fundamental concepts to advanced analyses and practical applications.

Week 1: Foundations of Machining & Tool Geometry

• Introduction to Machining & Material Behavior: Plastic deformation, stress-strain relationships, and mechanisms at the atomic scale.
• Machining Processes & Chip Formation: Types of processes, orthogonal/oblique cutting, chip types, and built-up edge.
• Tool Geometry Mastery: Reference planes, tool specification systems (ASA, ORS, NRS), angle relationships, and analysis of multi-point tools like drills and milling cutters.

Week 2: Mechanics and Friction in Metal Cutting

• Mechanics of Cutting: Merchant's Circle Diagram, determination of stress, strain, and strain rate.
• Shear Angle Models: Thin zone (Lee and Shaffer) and thick zone (Okushima and Hitomi) analyses.
• Friction Analysis: Nature of sliding friction, sticking/sliding zones on the tool face, and Zorev’s model for stress distribution.

Week 3: Oblique Cutting & Practical Operations

• Mechanism of Oblique Cutting: Analytical determination of rake angles (normal, velocity, effective), shear angles, and force relationships.
• Practical Machining Operations: In-depth study of turning, shaping, planning, slab milling, and drilling. Covers parameters, forces, power, material removal rate, and time calculations.

Week 4: Force Measurement, Tool Life & Advanced Topics

• Cutting Force Measurement: Methods using cantilevers, rings, octagons, and requirements for machine tool dynamometers.
• Tool Wear & Life: Types (flank, crater), mechanisms (abrasion, adhesion, diffusion), and variables affecting life (materials, coatings, fluids).
• Advanced Modules: Abrasive machining, economics of machining (optimization for cost/production), thermal aspects, and surface finish analysis.
