Mechanical Manufacturing

Résumé: Machining by material removal is a key mechanical manufacturing process used to produce parts with high precision and complex shapes while maintaining the material's original properties. This process is cost-effective and ensures excellent performance through the proper organization of operations, skilled labor, machine tools, and equipment. It offers precise tolerances essential in industries like aerospace, automotive, and tool manufacturing. Additionally, it supports a wide range of materials, including metals, plastics, composites, and ceramics, making it versatile across industries. Material removal machining is also valuable for repairing and refurbishing worn or damaged parts, extending their lifespan and reducing resource waste. This process remains a cornerstone of modern manufacturing, combining precision, adaptability, and efficiency. The handout "Mechanical Manufacturing," designed for second-year Mechanical Engineering students specializing in Mechanical Construction, introduces machining techniques with an emphasis on mechanical product manufacturing. Written in a simplified style with examples, it helps students grasp theoretical concepts and their industrial applications. The paper is divided into two parts: Metal Cutting Theory which covers cutting materials, cutting tool geometry, chip formation, cutting forces, tool heating and wear and selection of cutting parameters. The second part is Machine Tool Technology, it focuses on cutting motions, main components and kinematic chains of various machine tools.
