Abstract:
This document is about the work conducted during four months in the company Poclain Hydraulics. The aim was to improve the productivity of the turning operation on the cams MK04, in a factory environment but with the support of a laboratory. Was also in mind to improve the quality of the part and diminish or eliminate the unbroken chips. In that purpose the trajectories have been analyzed and modified, the cutting conditions studied and adapted, some tool changed, etc. The final result was an improvement of productivity to 140%, an amelioration of the chip breaking and of the part’s quality, leading to significant savings on the process.

Abstract:
The diploma thesis is focused on waterjet technology, dimensional and shape accuracy of manufactured parts. In the theoretical section, the principle of technlogy and its use in engineering industry at the present time, are described. Moreover, the theoretical section includes discription of every single parts of the machine of waterjet cutting, that are nowadays used. The biggest part of diploma thesis focuses on 3D cutting technology and on attachments for elimination of undercutting. Practical section focuses on dimensional and shape accuracy of manufactured parts manufactured by waterjet technology that makes use of 3D head and different cutting speed. The practical section also includes operating and maintenance cost of the machine. In terms of maintenance, real service life of components is compared there with a lifespan declarated by machine producer.

Abstract:
In this thesis, the main objective is to determine the price of selected construction project during its life cycle and assess operational costs. As a selected object is a family town house built in 1982 as a building type okal. The theoretical part is devoted to professional concepts and detailed information regarding the lifecycle, durability, budget, and wear-related issues. The practical part includes an itemized budget and the actual award of a selected object by using the software on valuation. The resulting values of individual valuation methods are then compared and graphically displayed. Furthermore I judge the actual operating costs incurred during the period.

Abstract:
This document is final report of an expertise project lead for ALPHA Company. The project focuses on the machinability characterization and comparison of various lamellar cast irons metallurgies. The comparison is performed in order to improve the casting process and the cast irons composition of brake and hub disk, to increase their machinability. The characterization of the metallurgies was made by tool life test with measurements of the cutting forces. Hardness and surface roughness measurements were performed too. Several Silicon nitride tools were tested. First an adjustment test has been performed to validate the machining parameters, and the methodology of characterization. Secondly, a reference test on Alpha’s cast iron brought reference data for the comparison of the various metallurgies to be tested. This test has improved the method of characterization. Cutting forces recording appeared as the most relevant and irrelevant measurements such as surface roughness were eliminated from the method. A test performed on a second cast iron showed that it has a lower machinability. Project succeeded to characterize and compare cast irons’ machinabilities, allowing the improvement of the composition by further tests.

Abstract:
The master thesis covers several issues linked to a substitution of headlamp screw fixation by a plastic nail. The thesis includes an analysis of the headlamp technology, including description of the prescribed durability tests. On the basis of the analysis some new designs of plastic nails are proposed, consistent with characteristics of plastic materials. Selected outcomes of the analysis have been tested as prototypes and verified with Finite Elements Method in SimDesigner including 3D modeling capabilities provided by the Catia V5. The feasibility study regarding a casting form of the new design of plastic nails and technical economic valuation for contingent assembly mounting is included in the thesis.

Abstract:
The thesis deals with silting of water reservoir Nové Heřminovy. There's describe design of artificial traffic and evaluate its effectiveness. To determine the flow of sediment into the reservoir with use a partially calibrated one-dimensional numerical model of sediment transport with deformation of bed is made in software HEC-RAS. Silting reservoirs is assessment with two methods, the results are compared and describes their limitations. Reservoirs silting evaluates through volume changes in reservoir storage in time.
