Stanovení optimálních řezných podmínek na základě vizulizace řezných odporů
Čupa, Jan
The thesis named Determination of optimum cutting conditions based on the visualization of cutting resistances is focused on the determination of optimum cutting conditions by the method of non-destructive testing - acoustic emission. Thesis specifically deals with the detection of cutting tool wear during continuous observation of machining process. The theoretical part of thesis starts with the theory of machining and wear mechanisms of cutting tools. Considerable attention has been paid to compilation from cutting force measurement. Final chapter of this part describes method of acoustic emission. Practical part of the thesis describes preparation and methodics of the experimental measurement. Next there is described measurement process with sharp and worn cutting tool. End of the thesis evaluates measurement results and also suggests practical application of the obtained knowledge.

Čupa, Jan
Bachelor thesis deals with the heat treatment of steel and its influence on the mechanical properties of steel. In the introduction is the procedure to production of raw iron and steel. Thesis shows the distribution of steel, depending on their chemical composition, method of production and labeling according to Czech National Standards. Thesis also describes structural phases and some transformations of iron alloys. The next chapter provides an overview of the heat treatment methods and part of the description of each species is usually their influence on the properties of steel. The final part of thesis deals with the lattice defects, that may arise during the process.
