La présente thèse a pour objectif d'étudier l'ensemble des artistes féminins qui ont exercé au sein de la manufacture de Sèvres entre 1850 et 1900. Cette période correspond à un moment clef de l'histoire de cette institution tant du point de vue administratif qu'artistique car elle marque une ère nouvelle avec l'apparition d'un style nouveau.Par ailleurs, les femmes employées à Sèvres sont de plus en plus nombreuses à participer aux expositions et aux salons. Certaines d'entre elles se sont distinguées par leurs talents et par leurs efforts à un moment à la société était, dans son ensemble, peu sensible à la condition féminine. C'est pourquoi cette thèse souhaite également aborder l'étude de quelques œuvres sous cet angle. Du point de vue artistique, l'étude porte une attention particulière à la chronologie des œuvres, à la spécialité, au style et au goût de chaque artiste. En dépit d'une certaine harmonisation d'ensemble qui est perceptible, en raison du lieu de production propre à la manufacture, certaines différences apparaissent.La première partie sera consacrée à la biographie des artistes. Les parcours de formation, leurs origines, leurs conditions de travail et leurs participations aux manifestations artistiques sont analysées. La seconde partie s'attache à étudier les œuvres du point de vue de l'analyse stylistique et de leur portée (notoriété acquise de l'artiste par l'intermédiaire de l'œuvre mais aussi message conscient ou inconscient, direct ou indirect que l'artiste a porté).La troisième partie est constituée d'un catalogue raisonné des œuvres. Il a été établi d'après les registres d'inventaires conservés aux archives de la manufacture de Sèvres. / The following thesis aims at studying all the feminine artists who worked in the Sèvres factory between 1850 and 1900. This period is a turning-point fort this institute on the administrative level as much as on the artistic one, because it represents a new era with the birth of a brend new style.Besides, more and more women working in Sèvres take part in exhibitions and workshops. Some of these women were particularly noted for their skills and their effort, while at this time the whole society was not interested by women condition. That's why this thesis will also throw light on some works with these ideas in mind. From the artistic viewpoint, the study particularly attracts our attention on each artist's specialties, styles and tastes. Despite the obvious global harmonization, due to the place of production of this factory, some differences appear.The first part concerns the artist's biographies. Their studies, their origins, their working conditions, but also their parts in artistic events will be analyzed. The second part will deal with the works from the stylistic analysis point of view and their impact (the fame reached by the artist through the work, but also the conscious or unconscious, direct or indirect message brought by the artist). Finally, the third part represents a descriptive catalogue of the works. It was established with the help of the inventory registers kept in the archives of the Sèvres factory.

The main aim of this diploma thesis is to design rotary manipulator for manual welding of hoist drums for EXYZ storage machine. The rotary manipulator is designed for improving of the quality of welds, which have been made in the static bearing welding process of hoist drum. The first part is concerned on the critical research of welding manipulators, which could be founded on the market. In the next part, there are sketched possible construction designs of welding manipulator based on the market offer. The main part of the diploma thesis is own construction design, which is made on the base of suggested concept of construction design.

The goal of the thesis is wear analysis of cutting inserts used for machining 42CrMo4 steel. Theoretical part of the thesis contains comparison of turning and milling machining processes, machining methods for ball screws made of 42CrMo4 and description of experimental methods of tool wear analysis. Experimental part of thesis contains methodology of cutting inserts wear measurement for chosen machining method. The following testing is focused on cutting insert wear as well as workpiece surface analysis. Thesis is finished with processing of measured data and overall evaluation of achieved results.

The thesis deals with the wear of replaceable inserts during the turning of structural hardened steel. The theoretical part describes a brief characteristic of turning technology, force loading on tools and tools used in turning. Moreover, it contains an analysis of the chemical composition of the machined material, its microstructure and microhardness. Machines and equipment used for the experiment and their specifications. The experimental part of the thesis describes the method of measuring and evaluating of tool wear, followed by the cutting tests themselves, documenting of the result and their evaluation. The conclusion of the thesis is the processing of measured data, the evaluation of achieved results and the proposal of further steps to improve the process.

This diploma thesis deal with evaluation of the impact in the scale of uncertaintly stiffness on the tool deviation during grooving process. By the affect of the insufficient stiffness in each parts of the machine, there is presented a mechanical vibration during the cutting process which may cause a damage to the surface of the workpiece, to the tool or to the processing machine. The change of the stiffness is caused in the result of tool wear, impact of setted cutting conditions and many others. In the first part includes teoretical introduction to field of the uncertainty and choosing suitable methods for the solutions. Chosen methods are Monte Carlo and polynomial chaos expansion which are procced in the interface of MATLAB. Both of the methods are primery tested on the simple systems with the indefinited enters of the stiffness. These systems replace the parts of the stiffness characteristics of the each support parts. After that, the model is defined for the turning during the process of grooving with the 3 degrees of freedom. Then the analyses of the uncertainity and also sensibility analyses for uncertainity entering data of the stiffness are carried out again by both methods. At the end are both methods compared in the points of view by the time consuption and also by precission. Judging by gathered data it is clear that the change of the stiffness has significant impact on vibration in all degrees of freedome of the analysed model. As the example a maximum and a minimum calculated deviation of the workpiece stiffness was calculated via methode of Monte Carlo. The biggest impact on the finall vibration of the tool is found by stiffness of the ball screw. The solution was developed for the more stabile cutting process.

Tato diplomová práce byla vypracována v průmyslovém kontextu, během stáže ve firmě Metso. Zlepšení obráběcího procesu zajišťovacích šroubů bylo cílem této práce, aby byla umožněna budoucí automatizace zakládání obrobku do stroje. Zlepšení bylo zhodnoceno na základě úrovně autonomie během obrábění, eliminace neprogramovaných zastavení stroje operátorem a dostačujícího odvodu třísek. Implementace automatických systému do číslicově řízeného obráběcího centra umožňuje zvýšení produktivity. Před automatizováním obráběcího procesu však musí být proces optimalizován. Zejména dostatečná fragmentace třísek a jejich evakuace jsou klíčové. Dlouhé nedělené třísky můžou poškodit systémy jako například automatický měnič nástrojů, dopravník třísek nebo průmyslového robota. Dostatečná lámavost třísek může být zaručena správným výběrem technologie a strategie obrábění, výběrem řezného nástroje a řezných podmínek pro daný materiál obrobku.

Within a range of study degree, the diploma thesis deals with a reconstruction design of three intersections and a single-span railway bridge along the Roviny street, Brno. The design is based on a familiarity with the territory as well as on traffic surveys. The proposed solution comprises the public transport lay-bys and pedestrians. The shape of intersections has been verified by means of vehicle-swept paths according to the TP 171 standard. The clearance under the bridge has been enlarged up to 4.80m and is in accordance with the S9.5 road category.

This diploma thesis deals with possibility of a non-contact tool corrections measurement and broken tool detection on CNC lathes. For this purpose was made a methodology for measuring and application in NC program. For testing the program in praxis was used CNC lathe SPM 16 with Sinumerik 840D controller. As measuring equipment was used a laser probe NC4 by Renishaw manufacturer.
