The theory of metal cutting is delved into in this publication, which is tailored for students studying Mechanical Engineering and manufacturing field at an advanced academic level. The main objective is to give learners the foundational knowledge and practical skills necessary to understand and effectively apply metal cutting principles.The content is made accessible by employing a clear and straightforward approach that meets the learning needs of students. To strengthen theoretical concepts and make complex ideas more tangible, practical examples and detailed diagrams are used throughout the text.The aim of this publication is to bridge the gap between academic learning and real-world engineering practices by blending theory and practice. We aim to contribute meaningfully to the development of these important technical skills, equipping students to excel in their studies and future careers in mechanical engineering, with the guidance of God.
