    Opis:
    The aim of the paper is a dynamic analysis of the starting and braking of the table of a numerically controlled CNC machine tool during idle motion. The experimental test was performed on the vertical table of the FV580A machining centre using the Phantom v1610 high-speed vision camera. The dynamics characteristics of the table movement were registered and the dynamics estimates of the movement were determined. The influence estimation of the parameters of the machine tool table motion on the value of the determined estimates was made. The results of measurements were discussed and guidelines and in order to minimise disturbances were formulated. The test results were summarised and discussed in the form of charts and tables. The directions of further research in the discussed subject area were also defined

    Opis:
    In the paper stages of the process of constituting a surface with the texture of the injection mold of a wheeled vehicle steering wheel using laser technology was discusses. During micromachining process with texturing there is a 5-axis CNC-controlled CNC machine TOOL LASERTEC 65 Shape used with a rigid monoBLOCK structure with Siemens 840D sl control, equipped with a fiber laser with a power of 100W, a wavelength of 1064 nm and a focal length of 181 mm. Processing technology was prepared using Autodesk Maya, Adobe Photoshop, Adobe Illustrator, NX9, Lastex v. 2.27.26 computer programs and machine tool control systems. Results of machining the steering wheel of a wheeled vehicle with a concentrated laser beam are discussed. Geometric structure of the surface after texturing was evaluated. Presented technology can be used to obtain the desired texture properties on the surface of the parts.

    Opis:
    The subject of microbiological tests of coolants presented in the work is the cutting fluid (emulsifying oil) of Fuchs ECOCOOL 68 CF3. The liquid was taken from the tanks of three different numerically controlled machines (Lasertec 65, MillTap 700, CTX beta 1250 TC), used with different intensity. The five most characteristic and popular media were used in the study: nutrient agar - plain, TSA medium (tryptone-soy-agar), medium with dichloran, rose bengal and chloramphenicol, Sabouraud agar with Chloramphenicol, Czapka agar. The incubation time was dependent on the type of microorganisms. After the specified time, the plates inoculated on the medium were subjected to visual observations and under the Leica DM 500 microscope. As a result of the observation, the following types of microorganisms (fungi and bacteria) were detected: Aspergillus Niger Tiegh, Candida Albicans, Saphylococcus Aureus, Micrococcus Luteus and Escherchia Coli and Citrobacter Freundia. The assessments were made in fixed periods. The results are presented as a function of the intensity of the use of cutting fluids. Microbiological analysis of machining fluids will allow for optimizing the time periods of using coolants and will also contribute to the protection of the operator's health and indirectly "extending the life cycle" of the technological machine.
