The paper presents the results of experimental studies on the influence of selected turning parameters on the quality of burnished automotive parts. The influence of the following parameters was investigated: r – tool nose radius, ε – tool nose angle, f – turning feed, v – turning speed on the Rz roughness parameter. Samples made of C steel were prepared by turning according to a five-level rotatable experimental design. The samples were then burnished to a depth of an=0.5 Rz and measurements were taken. The obtained results were processed using statistical and mathematical apparatus. A regression function was obtained determining the influence of the indicated turning parameters on the Rz surface roughness after the roller burnishing process.Burnishing is one of the methods of finishing metals and their alloys, sinters, and plastics, which consists in using local (…)
