The Study of the Influence of the Tracing Speed on the Result of Surface Roughness Measurement Using the Tactile Method

Abstract

This work concerns the problem of measuring surface roughness using the tactile method. The result of such a measurement is influenced by many factors, for example, the applied measurement parameters or changes in ambient conditions, e.g., temperature. The authors attempted to determine the influence of the tracing speed of the result of the profilometer tip on the roughness measurement of surfaces characterized by different types of irregularities. In the experiment, samples manufactured using various machining techniques were measured. Eleven selected roughness parameters were observed, including the most well-known ones, such as Ra, Rz, or Rt. The results obtained by the authors allowed them to determine which of the analyzed parameters are the most sensitive to changes in the tracing speed of the measuring tip, which is of great importance in the aspect of surface roughness measurements in industrial conditions. Owing to the obtained results, it is possible to determine in which cases it is possible to increase the speed of tip travel without reducing the reliability of the obtained results of surface roughness measurement.
