What is the effect of the cutting parameters of turning machining on surface roughness?

1. Cutting speed: Generally speaking, increasing the cutting speed within a certain range can help reduce surface roughness. This is because higher cutting speeds can reduce the formation of chip tumors, thus making the machined surface smoother. However, when the cutting speed is too high, the surface roughness may deteriorate due to increased tool wear and other reasons.

2. Feed: As the feed increases, the surface roughness value usually increases. This is because the greater the feed, the greater the height of the residual area, thus making the surface rough.

3. Depth of cut: The depth of cut has a relatively small effect on surface roughness. However, too small a depth of cut may lead to unstable cutting force, but affect the surface quality; too large a depth of cut may cause vibration, making the surface roughness worse.
