Cutting surface roughness determinants have?

Cutting surface roughness depends mainly on the following three aspects:

(1) the inherent parameters of cutting system, such as speckle pattern, focal length, etc. ;

(2) can be adjusted in the process of cutting process parameters, such as power size, cutting speed, auxiliary gas type and pressure etc.

3. Processing material physical parameters, such as the absorption rate, melting point, viscosity coefficient of molten metal oxide, metal oxide surface tension, etc.

in addition, the thickness of the machined part also has great influence on cutting surface quality. Relatively, the smaller the thickness of the metal workpiece, the higher the cutting surface roughness level.
