“…Additionally, the influence of disturbances from profilometer construction's susceptibility to changes in the center of gravity position during movements of the X-arm with the measuring tip was examined. This study builds upon and complements research related to errors in contact profilometry [13,14]. Dependencies resulting from thermal expansion directly affect the parametric values of surface geometry texture.…”

“…Contact methods, with the most common devices being stylus profilometers, use a diamond measurement tip that moves across a surface and records vertical deviations. Although these are well-known methods, they are sensitive to vibrations, noise, and other disturbances [ 8 , 10 , 11 ] as well as thermal effects [ 12 , 13 , 14 , 15 ] and geometric errors in the measurement tip [ 16 , 17 ]. Compared to other methods, they are time-consuming [ 18 ], have low measurement throughput, and require direct contact with the sample, which can cause scratching and damage to the surface being examined [ 19 , 20 ].…”

“…Unstable conditions can affect both the measured element and the profilometer’s structure. In another study, Grochalski et al [ 14 ] also demonstrated that internal heat sources, originating from the contact profilometer drives, affect measurement accuracy. However, the application of thermal stabilization can reduce these errors by about 90%.…”

This work presents issues related to selected errors accompanying spatial measurements of surface roughness using contact profilometry. The influence of internal heat sources, such as engines or control electronics, on the thermal expansion of the drive responsible for the measurement probe’s movement in the X-axis direction was investigated. In terms of starting measurements on a thermally unstable device, the synchronization error of individual profile paths was 16.1 µm. Based on thermographic studies, the time required for full thermal stabilization of this drive was determined to be 6–12 h from when the device was turned on. It was demonstrated that thermal stabilization of the profilometer significantly reduced positioning errors of the measurement probe on the X-axis. Thermal stabilization time should be determined individually for a specific device variant. This research also determined how changes in the center of gravity caused by the measurement probe’s movement affected the overall rigidity of the profilometer structure and the leveling of the tested surface. Laser interferometry was used for this purpose. The determined vulnerability of the profilometer structure was 0.8 µm for a measurement section of 25 mm. Understanding the described relationships will reduce errors associated with conducting measurements and preparing equipment for tests. Additionally, it will enable the correct evaluation of surface geometry.

Possibilities of a Hybrid Method for a Time-Scale-Frequency Analysis in the Aspect of Identifying Surface Topography Irregularities

The article presents research results related to assessing the possibilities of applying modern filtration methods to diagnosing measurement signals. The Fourier transformation does not always provide full information about the signal. It is, therefore, appropriate to complement the methodology with a modern multiscale method: the wavelet transformation. A hybrid combination of two algorithms results in revealing additional signal components, which are invisible in the spectrum in the case of using only the harmonic analysis. The tests performed using both simulated signals and the measured roundness profiles of rollers in rolling bearings proved the advantages of using a complex approach. A combination of the Fourier and wavelet transformations resulted in the possibility to identify the components of the signal, which directly translates into better diagnostics. The tests fill a research gap in terms of complex diagnostics and assessment of profiles, which is very important from the standpoint of the precision industry.
