For average work, a finishing cut requires a slower feed than a roughing cut.

Explanation:
Finishing vs roughing relies on feed rate to manage surface finish and dimensional accuracy. Finishing cuts remove less material per pass and use a slower feed, which lowers the chip load, reduces tool deflection and heat, and yields a smoother surface. Roughing cuts remove material more aggressively with faster feed, trading surface quality for material removal rate. For average work, this is why the finishing cut is performed with a slower feed than the roughing cut.
