What are the causes of unsmoothness of machined parts` curve surfaces and how to solve them?

The main causes of unsmoothness of machined parts` curve surfaces are cutter vibration and cutters not sharp.

Let's analyze the cause of the vibration of the tool in CNC Machining curve surface parts: The reason is the same as the reason that the cutter vibrate in the broken knife. Here we talk about the most important factor.

1) The protruding length of the tool is too large. In this way, the tool is deformed greatly in CNC Machining curve surface parts, and the machining process is constantly changing, resulting in the unsmoothness of the machined parts` surface.

2) There are staircase residues in CNC machining curve surface parts. When there is a ladder-shaped residue, the cutting process changes, and the tool deformation is different, so the machined parts` surface is not smooth.

3) Cutting depth is too small. The phenomenon of machining slippage results occurs, cause the machined parts` surface is not smooth.

4) Cutting tool radial runout is large. At this time, the machining state of the tool is very unstable, which affects the machining effect.

5) Cutting depth is too large. The cutting force is too large and the tool deformation is large, resulting in the surface of machined parts is not smooth.
