Proposals of Frequency-Based and Direction Methods to Reduce the Influence of Surface Topography Measurement Errors

Various methods, based on both surface frequency and direction, can be alternatively proposed to reduce the influence of high-frequency measurement data analysis errors. types details were studied, e.g., cylinder liners after plateau-honing process, plateau-honed with additionally burnished oil pockets (dimples), turned, ground, milled or laser-textured. They measured stylus non-contact (optic) techniques. It was suggested support various frequency-based Frequency Spectrum, Power Spectral Densities Autocorrelation Function, direction techniques provide reduction errors in detection extraction Results especially valuable for regular studies when are difficult identified.
