Final answer:
A finishing cut in machining is a precise, lighter cut used to achieve the final dimensions, tolerances, and surface finish of a workpiece, as opposed to a roughing cut, which removes material quickly without much regard for the final details.
Step-by-step explanation:
A finishing cut is a term often associated with machining, and it is performed after the initial roughing cuts. While roughing is about removing large amounts of material quickly, with less concern for surface finish or final dimensions, a finishing cut is done to achieve the final dimensions, tolerances, and surface finish. It involves lighter cuts and refined tool paths to smooth out the surface and bring the workpiece to its final shape.
This concept can be likened to the process of filmmaking where the director goes through all the takes during post-production, selecting the ones that best fit the vision for the movie. Similarly, in the context of production in the short run, such as tree cutting with a two-person crosscut saw, finishing cuts would refer to the final, more precise cuts made to the lumber to ensure it meets specific requirements, whereas roughing cuts would be the initial, less precise actions to fell the tree and start processing the timber.
