Analysis of Surface Roughness

Hi All,

I am looking for analyzing the surface roughness both 2D and 3D from set of coordinate values. Is there any tool in MATLAB that can help me plot roughness profiles (2D and 3D) and measure the profile parameters such as Ra, Rz, Rt, etc.? Please help me if you have any MATLAB code to do this.

With regards, Uma Shankar

I have the same problem

@Mohannad Alsheikh Essa, again "Yes", just like I told @Avdheshkumar Kakadiya earlier. Did either of you see my answer below? It was accepted. The formulas are simple to implement with the functions I listed. You could also see immse().

Answer 1

[Image Analyst]

You can use functions like sqrt(), mean(), etc. Most of the formulas are pretty simple.

Hi, Thanks for your reply. Yes it is easy to do that. But I am having much data which I want to analyse for surface roughness. Is there any MATLAB app or some tool in MATLAB where I can directly feed the data and analyse the roughness parameters? Thanks and regards

[Image Analyst]

Probably no one wrote an app to do something as simple as a sqrt. You can write your own if you want.

You can search the web for "surface metrology matlab" or check the File Exchange: https://www.mathworks.com/matlabcentral/fileexchange/?utf8=%E2%9C%93&term=metrology

Thanks. This is helpful. regards

What about the extraction and waveness though? The roughness measurement would be wrong if the waveness is not removed from the main profile.

Hey, have you worked out this code for analyzing surface roughness? Could you give me some suggestions using MATLAB for this topic? Thank you!
