    Opis:
    The paper presents evaluation of modal analysis usefulness for deter-mination of milling process stability. In the first phase of the study experi-mental modal analysis was performed and using CutPro 9.5 software, stability lobes were generated. In the next step, machining tests were carried out. The last stage of the experiment involved verification of modal analysis usefulness for evaluation of milling process stability based on sur-face roughness measurements. Conducted research allowed to state that modal analysis can be a useful tool for determining milling process stability.

    Opis:
    This paper presents a comparison of the impact of the programming methods of a CNC miller on the machining effects. As a part of the study, the test samples were made of the EN AW-2024 aluminium alloy. The CNC machining programs compared were developed with two programming methods: by inputting the CNC machining program directly from the CNC miller's control panel (machine level programming) and in a CAM software environment (CAM programming). The machining effect indicators adopted included: machining time, surface quality, and dimensional deviation of specific geometrical features. A measurement of the machining times revealed than the CAM programming reduced the machining time up to 20% from the machining time of the machine level programming. A conclusion stands valid that CNC machining programs developed in the CAM software environment are more efficient than CNC programming directly with the CNC miller control panel, most likely due to the machining path optimisation in CAM. In addition, given the experimental test results, it was found that smaller machined errors were also obtained for CAM programming. To conclude, the comparative analysis revealed that CAM programming provided better machining results than the machine level programming.

    Opis:
    The paper presents an analysis of surface roughness following milling of thin-walled components made of aluminium alloy EN AW-2024, taking into account the three different machining strategies and rolling direction of semi-finished product in the form of a plate combined with the milling feed. The aims of the study were to compare the results of machining using various technologies and show the best of them, providing the smallest roughness of the component following milling, as well as to determine the impact of rolling direction of the plate on the quality of the end surface. Measurement results of surface roughness parameters were provided information about the progress of the machining process.

    Opis:
    The paper presents results of wear measurements of carbide shank milling cutters during machining of AlSi10Mg casting alloy. The comparison was made between blades wear of milling cutters without protective coating, with TiB2 coating, and with TiAlCN coating. All cutters had identical geometry dedicated to milling of materials of ISO N group. To assess blades wear degree, measurement of two direct indicators, i.e. VBC and VBBmax, and one indirect indicator, i.e. machined surfaces roughness, were used. Received results allowed to determine usefulness of using selected protective coatings in machining of aluminium alloys, especially Al-Si casting alloys.

    Opis:
    The paper presents an analysis of the influence of machining strategy and the technological history of semi-finished product on the deformation of thin-walled elements made of aluminium alloy EN-AW 2024 after milling. As a part of this research work, five machining strategies are analysed. Additionally, the rolling direction of the plate (longitudinal and transversal) is taken into account as a technological history. During the research, the focus is set on the effects of the machining strategies i.e. HPC, HSM and conventional machining as well as their combinations on the post-machining stresses and deformations. Each of these strategies has a different range of technological parameters, which results in differences in machining efficiency and introduces post-machining stresses to the surface layer of the workpiece that vary in values and nature (i.e. compressive stresses or tensile stresses). The conducted study shows that larger deformations were obtained for transversal rolling direction in each analyzed case. The lowest deformation both for transversal and longitudinal rolling direction were achieved for the HSM and CM strategy.
