Abstract:
The diploma thesis deals with the influence of the volumetric accuracy of the machine tool on the size of the assessed work space. The impact assessment was carried out on the basis of tests of a three-axis vertical CNC machining center. The thesis is divided into two parts, theoretical and practical. The theoretical part is focused on geometric / volumetric accuracy of machine tools, measuring technique for measuring geometric errors and Design of Experiment. In the practical part, there is an analysis of the Design of Experiment according to Shainin, description of the work with the measuring instruments and the measurement of the geometric / volumetric accuracy of the machine including statistical evaluation. The output of the thesis is the description of the influence of volumetric deviation on the size of the measured work space by means of statistical methods.

Abstract:
The dissertation thesis is used as a methodology for prediction of selected parameters of rotational kinematic pairs of machine tools. The motivation for its writing has been continually increasing requirements for parameters (performance, accuracy, static and dynamic stiffness) of machine tools. The methodology takes into account the availability of suitable measuring devices and description of the design of rotary kinematic pairs. It will be useable for predicting the behavior of rotational kinematic pairs, even at the design stage by applying results to the machine design. The work is processed so that first is used a system approach to suggest methodology for prediction of the behavior of rotary kinematic pair in CNC machine tools, planning measurement strategy and verifying the results, including applications for specific kinematic chain of the selected machine. Based on this system approach and the resulting methodology, the measurement of the rotary kinematic pair was performed. The results of the system approach and measurement are generalized in the form of recommendations for designers of machining centers, allowing to increase the accuracy of the rotational kinematic pair.

Abstract:
This diploma thesis describes realization and testing on-the-fly measurement using tracking interferometer. This measurement enables to achieve higher amount of measured points and decrease time of machine tool calibration. Calibration and verification values of machine parameters, as well as time of measurement and other details of this method are compared with results of conventional method called trigger. To evaluate the quality of volumetric compensation created from calibration values, we use verification measurement of circular interpolation.

Abstract:
This work is focused on the software compensation of the geometric and volumetric errors. In the thesis there are descripted the measuring instruments suitable for measuring geometric and volumetric errors of the machine tool. In addition, there are described control systems and selected software compensations currently used in the machine tools. In the experimental part of the thesis there is briefly described the machining machine where the experiment was performed. Detailed procedures for using the used measuring instruments are also described. The aim of this thesis is to determine the influence of the size of the compensated volume on the geometric and volumetric precision of the machine tool.

Abstract:
The goal of the thesis was applying multiparametric diagnostics to determine the state and wear of a high-speed milling machine. In the theoretical section, selected areas of multiparametric diagnostics have been described as well as a significant focus on vibrodiagnostics. The chosen methods for the practical section were incorporated into the group “metrological diagnostics”. Several different types of measurements have been performed on the designed test piece. The measurements were analyzed and lead to these specific results: a drawing of the test piece, a structured methodology for evaluating the test piece, recommendations for diagnostics of the specific machine, and proposals for the future development of the field of metrological diagnostics.

Abstract:
This thesis solves the impact of conventional compensation to the volumetric accuracy of the CNC machine. It is therefore a practical research work, where are in the theoretical introduction mentioned requirements for machine tools, the types of errors that can occur on three-axis kinematics, compensation for the control system Siemens Sinumerik 840D sl and devices by means of which are these compensation under the work formed and subsequently verified. In this work can be seen the measured values and graphs from each measurements, a detailed analysis of the results and drawing conclusions from these results.
