    Analyzing surface integrity elements of hard turned 16MnCr5 steel
    (Національний технічний університет "Харківський політехнічний інститут", 2023) Molnar, Viktor
    Surface integrity plays a determinant role in the functional requirement of precision machined parts. In the automotive industry billions of components are manufactured by using case hardened steels. In this study some surface integrity elements, such as surface roughness or residual stress are analyzed based on systematic machining experimental plan to optimize the applied cutting parameters. Recommendations are made for these parameters based on the measurement data and some widely used functional requirements.

    Wear resistance of hard turned surfaces
    (Національний технічний університет "Харківський політехнічний інститут", 2022) Molnar, Viktor
    The quality of working surfaces plays an important role in automotive industrial components. One of the main characteristics of such surfaces is their wear resistance. In this study external cylindrical surfaces were analyzed. A Design ofExperiment methodology was applied and hard turning experiments were carried out to analyze the effects of the cutting parameters on the 3D surface roughness values of reduced peak height, skewness and kurtosis. The study confirmed earlier findings that at lower feed the wear resistance is higher based on the analyzed roughness parameters. The cutting speed and the depth-of-cut do not influence these parameter values significantly.
