What do burrs in machining refer to?

Burrs in machining refer to sharp edges or rough projections left on a part after cutting. During machining operations, such as milling, drilling, or turning, material is removed from a workpiece. This process can create small, jagged edges where the tool interacted with the material, resulting in burrs. These burrs can impact the functionality, appearance, and safety of the finished part, making their removal an important step in the machining process.

Effective deburring techniques are used to ensure surfaces are smooth and safe for handling, as well as to meet the required tolerances and specifications. Understanding what burrs are and how they affect the final product is crucial for anyone involved in machining and manufacturing.
