    General purpose of the doctoral thesis here presented was to define optimum machining conditions for sintered WPW carbon materials mostly used as a facing cover of metallurgical furnaces. SGL Carbon Poland SA Racibórz mostly use the WPW-65 carbon material. Almost $60\%$ of its product are made of the WPW-65. To carry out certain amount of cutting test it was necessary to built an experimental unit based on special adaptation of vertical milling machine. Special Kistler dynamometer to the machine table was attached and the cutting force $F_{c}$. tool displacement "x" were recorded (that last by means of laser vibrometer). while the chip formation with high speed camera was recorded. The aim of this study was to determine how technological parameters such as depth of cut - $a_{p}$ and feed - f. as well as cutting angle $\gamma$ of attack tool influence chips formation, theirs granularity and finally - the energy of the process. The results obtained from the study were analyzed using DIAdem 10.2 and specially written software to plot the density distribution functions for energy of chips fragmentation and overall energy consumption. On the base of whole results and the linear programming method an optimum cutting conditions for sintered WPW - 65 carbon material were raised. Also a proposal of new methodology for machinability investigations of brittle materials was presented.

    Professor Andrzej Lasota's theories in engineering
    (2008) Rusek, Piotr
    Professor Lasota's achievements in the field of engineering are based on two principal aspects: profound theoretical backgrounds and perfect knowledge of phenomenological processes. That allowed him to solve many different problems of engineering.

    Welding sequence analysis
    (Data obrony: 2009) Hernández Arriaga, Isaac
    Wydział Inżynierii Mechanicznej i Robotyki
    Numerical analysis of the residual stresses and strains by the FEM after the welding process of selected structural elements is presented. Experimental investigations shows that the difference between numerical and practical investigation might be minor than 10%. The result were obtained when the MAG process was employed to weld several, typical structural elements. There exist important application of the numerical method presented which support the plant engineers to establish better welding sequence for lower stresses and/or strains.

    Wpływ technologicznych parametrów napawania brązu na podłoże stalowe na wybrane właściwości użytkowe napoin

    The influence of the selected parameters pad welding by the MIG method of the tin bronze CuSn6 pad welding on the difficult - to - weld steel (steel type 45) on the chosen properties of welds was discussed. The investigations ware made to determine the ranges of the technological parameters of the padding which guaranteed an adequate quality of the welds. Using mathematical planning of experiment showed the influence of the technological parameters of the padding on the geometry of the bronze layer. The influence of the selected parameters of the tin bronze pad welding on steel on the chosen properties of welds also was discussed. The technological parameters were held constant during the padding which guaranteed an adequate quality of the welds and a small base material fraction for investigations usable properties. The influence of the pitch of runs was definited during investigations on the geometry of the bronze layer. Hardness was assigned for padding welds, the base material and the zone between padding weld and base material. Detection of possible internal defects of padding welds was the aim of metallographic and X-ray radiography investigations of welds. The bend test was used to assess the level of the weld adhesion to the base material. The hardness investigations showed the influence of the number of bronze layers on their hardness. The essential influence of the surfacing process on the hardness of the base material was not found. The normal bend test showed the good adhesion of the surfacing layer and steel. The presence of the smali defects did not have the essential influence on the usable properties padding welds. The results of tribological tests of single and two layer CuSn6 bronze welds of padded on the steel base were compared with these for the cast bronze of the same chemical composition. Friction coefficients and linear wear of pairs under sliding were measured for the lubricating environment of mineral and synthetic oils. The investigation revealed the dependence of friction coefficient on the number of layers in the weld pad and on the lubricating environment. Differences were not observed for the linear wear of layered and comparative samples working in the environment of synthetic and mineral oil.
