Deburring is a vital finishing operation in modern manufacturing processes that involves the removal of unwanted material projections, commonly referred to as burrs, from machined components. Burrs are typically formed during machining operations such as drilling, milling, turning, and grinding due to plastic deformation of the material. These projections, although small, can significantly affect the functionality, safety, and aesthetic quality of the final product. This research paper presents a detailed study of deburring, including its definition, causes, and classification of burrs. Various deburring methods, such as manual, mechanical, thermal, electrochemical, and cryogenic processes, are discussed in detail. The paper also explores tools and equipment used, advantages and limitations, industrial applications, and future advancements. The study highlights the importance of deburring in ensuring high-quality production and improving the performance and reliability of manufactured components.
