What is the process of removing any raised material, shavings or slivers of metal left after drilling?

The process of removing any raised material, shavings, or slivers of metal left after drilling is known as deburring. This is a critical step in metalworking and aerospace manufacturing, as it helps to ensure that the edges of the drilled holes are smooth and free from any sharp edges or residual material that could pose safety hazards or affect the integrity of the assembly.

Deburring can be accomplished through various methods, such as manual filing, using deburring tools, or employing mechanical methods like tumbling or sanding. The primary goal is to create a safe and clean surface that is ready for further processing or assembly.

Other methods such as polishing, grinding, and shaping serve different purposes. Polishing focuses on achieving a smooth, shiny finish on surfaces, grinding involves removing material to achieve precise dimensions or shapes, and shaping is utilized to create specific contours or forms in the material. While all these processes are important in machining and assembly, deburring specifically addresses the issue of residual material left from the drilling process.
