Abstract
A comparison between the results of tribological investigations and four surface integrity parameters, i.e. macroscopic and microscopic residual stresses, roughness and microhardness, was performed. The samples in the form of two parts of guide gibs from steel embedded into a cast iron bed were subjected to side milling by three different tool tips. The performed analysis yields some mutual relationships between surface integrity and friction coefficient, e.g. low roughness lead to high friction coefficient, the highest compressive residual stresses were found for the lowest friction coefficients, or increasing cutting speed leads to a decrease in microhardness.
