Abstract

The functional requirements of precision machined parts can be expressed among others by topography parameters. In the automotive industry there is an increased need for the application of high-accuracy quantifying parameters. In this study wear resistance and the fluid retention ability-related 3D surface texture parameters are analyzed based on hard turning and grinding experiments. The less frequently applied functional parameters (Sbi and Svi) are compared to the high-accuracy volume parameters (Vmp and Vvv) to obtain information about the reliability of the former ones. It was found that the correlation between the two types of parameters are quite weak.
