Why is it important to remove burs during machining?

The significance of removing burrs during machining primarily lies in enabling accurate fitting between components. Burrs are unwanted protrusions or rough edges that can form on the edges of machined parts. These imperfections can interfere with the precise alignment and proper assembly of components, leading to issues such as misalignment or inadequate sealing in joints, which can ultimately affect the functionality and performance of the final product.

Accurate fitting is crucial in aerospace applications, where even minor deviations in component dimensions can have serious implications on the overall integrity and safety of aerospace structures. By ensuring that burrs are removed, manufacturers can achieve tighter tolerances and smoother mating surfaces, which are essential for maintaining the structural integrity and performance of aerospace systems.

Although factors like aesthetics, material sticking, and noise reduction are relevant considerations, the primary concern in the context of accurate engineering and assembly is the impact of burrs on fitting precision.
