This thesis deals with the performance of the measurement accuracy in the optical measuring systems. The first part describes basic principles of metrology and the guidelines of the expression of uncertainty and the factors which influence measurement result. The second part classifies optical measuring systems and describes some measuring principles of them. The final part compares two optical gauges and the evaluation of some of their characteristics through the use of very simple experiments.

Determining accuracy of wax patterns is an important in wide implementing rapid prototyping methods in investment casting. This experiment is comparing wax pattern accuracy produced in classical metal die and silicone mould. It has been found out, that wax patterns produced by the silicone mould are ounly about one or two accuracy steps worse then wax patterns produced by classical metal die.

The aim of my diploma thesis was to find the possibilities of reaching the dimensional tolerance in the individual phases of casting by the investment casting process. The accuracy of the selected wax patterns and castings were measured by a caliper. At first the selected dimensions of the wax models were measured right after taking them out of the mold and then they were measured during seven days. The castings were measured after pouring. The obtained figures were statistically evaluated. The results show that the large-scale and thick-wall wax model should be coated after seven days of stabilization because the dimensions of the wax model are not stable.

This diploma thesis deals with a production process cast body of the stator the in the company Papcel, a.s., Litovel. The first part is focused on the description of the current production process. The production is realized with several manufacturing machines and hand machining also. The second part analyzes available changes of the current technology and describes alternative procedures and production facilities. The CNC machine-tool ŠKODA FCW 150 seems to be the most effective way of production, which could increase the labor productivity, cut the share of manual works, reduce a risk of a human error and to increase the final product quality and accuracy. The final part of the thesis evaluates the machine and preparation times for a single production, including assembly operations and financial impacts of the investments on the company costs.

This master‘s thesis is concerned by accuracy cutting of the process. The aim of this graduation theses is to describe metodology quantification of the parameters accuracy of cutting process and to check it. Firstly, there are the parameters accuracy of cutting process identified. Secondary, there are particular technological influences over accuracy of shaping process characterized. In the conclusion, there are characteristics accuracy of shaping process quantified and tested in practice.

New materials used at construction gauge they are though expensive, but shall they meaningful influence over making and metrological characteristics. Work evaluation influence these material on increasing quality concrete gauge.

Diploma thesis offers a new approach to the measuring of geometry errors in the machine tool workspace with the aid of laser tracker. There is a method of data acquisition and also the Matlab programs for data processing suggested in the thesis. This method can determine the accuracy and repeatibility of positioning and angular displacement of the numerical controlled axes of the measured machine tool and it compiles its mathematical model. All the gathered knowledge is used to evaluation of geometric accuracy of the virtual machined workpiece.

This diploma thesis deals with a machining process of the forging of connecting rod in the company SANBORN a.s mainly for reason to propose a more effective method of machining. The first part is focused on the analyse of actual process of production which is realized on several manufacturing machines. On second part are proposed the increases in efficiency of single machining operation and is used the modern multi - fuction machining centre OKUMA MULTUS which will increase the productivity and quality of machined part. In final part is applied for evaluation of machining and secondary production times and is performed the total financial analyse.

This diploma thesis deals with a positioning accuracy of global positioning system GPS and satellite augmentation system EGNOS. My thesis describes the procedure for investigation of the errors in previously mentioned global navigation satellite systems according to L10 regulation and further on an elaboration is worked out in more detail far beyond the requirements of this regulation. In the practical part, an assessment of errors on a real data sample is done, the errors are measured with using a static observation, and later a discussion is carried out on the achieved results.

The presented diploma thesis deals with the control of the geometric accuracy of the parts produced by additive manufacturing technology selective laser melting. The paper first analyzed the work of the other authors dealing with this issue. Based on obtained informations from this analysis were developed benchmark test parts for quality control of production on a commercial machine SLM 280 HL supplied by SLM Solutions GmbH. The work was carried out several tests to determine the appropriate parameters of construction parts. These tests, their results and conclusions are fully described in this papper.
