Methods of Machine Tool Thermal Error Compensation
Hanzal, Jiří ; Hermanský, Dominik (referee) ; Minář, Petr (advisor)
Thermal error caused by the thermal deformation is one of the most significant factors influencing the accuracy of the machine tool. This paper presents an overview of the methods of measurement, regulation and compensation of thermal errors. It also deals with the research of research centers and their projects. At the end of the thesis we are dealing with measuring of temperature deviations on machine tools MCV 754 Quick. For the tested machine tool, a methodical proposal of temperature compensation was designed using the grey neural network model with convolution Integral. This paper aims to give a basic introduction of the whole process of the spindle thermal error compensation.

Thermal effects in machine tools
Marek, Tomáš ; Štěpánek, Vojtěch (referee) ; Hermanský, Dominik (advisor)
This bachelor thesis deals with thermal effects on machine tools. The work is divided into several section. The first part is an introduction to basic thermomechanical concepts. The next part is focused on the deformation caused by heat during machining and the negative impact on the accuracy of the workpiece. Furthermore, there is a problem in the prediction and subsequent of thermal error compensation. The last part is devoted to the analysis of a specific part of machine tools. It examines various company solve the problem of thermal effects on the spindle.
