Which type of cut is primarily concerned with surface finish and dimensional accuracy?

The finishing cut is primarily concerned with achieving a high-quality surface finish and precise dimensional accuracy on a workpiece. This type of cut typically follows a roughing cut, which is focused on removing large amounts of material quickly and is less concerned with the finish or exact dimensions.

In contrast, a finishing cut is usually performed with finer tools and slower speeds to ensure that the final surface meets specific standards. The tools used in finishing cuts are designed to leave a smoother surface and tighter tolerances. This is essential in many manufacturing applications, where components need to fit together precisely or have a surface finish that meets aesthetic and functional criteria.

While milling and turning cuts can also achieve good surface finishes and dimensional accuracy, these processes encompass broader categories that may include both roughing and finishing cuts. Therefore, finishing cuts are distinctly aimed at perfecting the surface and ensuring tight dimensions after the bulk of material has been removed.
