This paper analyses the method of denoising surface roughness profile signal using self-adaptive filtering technique.The working principle of self-adaptive denoising has been introduced.Method of combining of self-adaptive filter and least square error(LMS) algorithm has been designed.Results obtained from sin-wave with noise are validated using the LMS algorithm to eliminate noise.Comparison of caculating surface roughness mean line between self-adaptive Gaussian filtering meanline and ordinary Gaussian filtering meanline has been presented.From the simulation of self-adaptive denoising it is observed that the designed method can be used as a denoising method in the surface roughness measuring.
