The diploma thesis is divided into two parts - theoretical and experimental. The theoret-ical part deals with machining of foundry as a production technology, where emphasis is placed on gravity casting. Further the theoretical part deals with the problems of the thermal regime of mold, dimensional stability and defects of castings, where this issue is important for experimental measurement in the foundry and its evaluation. The experimental part transmits the findings from the theoretical part to reality by measuring castings. Here is a description of the measured castings and the main parts of the temperature and casting temperature measurements, casting dimensions measure-ments. It follows the evaluation of casting defects. At the end of the work is discussed the measured results with their possible causes and suggestions for further solution. |
