Surface Roughness | Digital Alloys

The standard "as-machined" (CNC milling or turning) surface roughness is ~3 μm. An additional finish machining pass can be performed to reduce the surface roughness to ~1 μm. For many engineering applications this roughness is acceptable. There are other post-processing options, not referenced in the above chart, that are worth mentioning. For interior surfaces that cannot be reached via ...

Simulation Analysis of Surface Roughness for .

Surface roughness is one of the most important evaluation indexes in machine cutting. In order to analyze how the tool path affects the roughness of the surface after milling, series of simulations are implemented in MasterCAM. We set up the same processing conditions with same parameters such as speed, material and feed rate etc. in these simulations, but different processing paths are used.

However, surface roughness can be quantified and usually this value is used to indicate quality or level of surface finish. For example, surface roughness of a milled surface is 2µm (value to quantify) or the surface finish of the milled surface is very good (attribute to qualify). Similarly in conventional tool based machining, surface roughness can be mathematically expressed with the help ...
