Manual programming of CNC machines
Stránský, Michal ; Sedlák, Josef (referee) ; Píška, Miroslav (advisor)
Theme of my bachelor thesis is focused on the manual programming of CNC machines. The thesis is divided into 4 parts. First part is focused on the history and introduction of programming of CNC machines. Second part explains manual programming of CNC and its place in manufacture process. The third part is focused on a automatization of manual programming works. Last part of the bachelor thesis contains a program made with the SINUMERIK 840D control system.

Solution technology of two groove guide pulley production.
Šimonek, Ondřej ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
Technology deals with the production of the two - groove guide pulley for two types of semiproducts. Technological process of production solves the production of the guide pulley from the first gripping of semiproduct to handing over of the guide pulley to the warehouse. Semiproducts are two types of castings with different separating plane. The material of the guide pulley is always gray - cast iron ČSN 42 2420. Production method is cutting operation with CNC machines. The production uses tools with interchangeable cutting tips. The aim of this work is to find the most optimal method of production from both time and economic perspective and to compare the two variants.

Programming CNC machines with digital control system Fanuc.
Tkáčová, Alena ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
The theme of this bachelor thesis focuses on the CNC-programming, which is currently used in many branches of the machine industry. The theme is elaborated and divided into well-arranged chapters. The first part deals with the development of the control system of cutting machines, beginning with the hard automatization and ending with the computer-controlled cutting machines. In the second part there is described the general control system Fanuc including the machine description. The third part contains the application of the real cutting procedure - with the NC program for turning and milling of the sample component in a certain company.

Solution technology of two groove guide pulley production.
Pokladník, Robert ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
Technology compiling two groove pulley making for two types of billets. As a billets is used in both cases a cast iron EN-GJL-250. The technological process solves production of both variants from designing the billets to trans-mission to the storeroom. The production is realized through cutting operation by CNC machines. The tools are selected with cutting tip. Finaly both variants are compared from economical perspective.

Controlling CNC machine tools with focus on three-axis milling - triaxial milling machine EMCO and its control systems
TETOUR, Milan
The first section of this thesis describes the problem of programming computer numerical control (CNC) machines and the way how they are currently used in industry. The next section compares current control systems of the CNC machines, the general principles of programming with the possibility of using workroom oriented milling. Then the EMCO machine is described, its operation, setup, practical advices and also examples of the Sinumerik 840D control system by Siemens. The final section introduces a practical demonstration of machining by using the NC program for milling a representative component on the machine metioned above.
