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.

Machining on a CNC machine including automatic measurement
Kubín, David ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
The topic of the bachelor thesis is the analysis and integration of the measuring cycle into the machining process on a CNC machine. The topic is dealt with in two parts, theoretical and practical. The theoretical part briefly discusses the history of NC/CNC machines, including the basic control modes of NC/CNC machines and the structure of the NC programme. Furthermore, the control systems produced by renowned companies available on the Czech market are presented. Besides other facts, measuring cycles in control systems and their examples are also mentioned in this part. The practical part of the bachelor’s thesis is focused on the creation of a suitable illustrative component, the subsequent compilation of operational data and documents into the technological preparation of the production. The production of the component and its subsequent measurements are based on these data. The production process ends with the evalution of the information obtained.

Design of operator workplace of machining center
Kříž, Jan ; Pavlík, Jan (referee) ; Novotný, Tomáš (advisor)
The presented work contains the parameters and rules relevant for the design of the inter- face between the machining center and it's operator. All of information were obtained by search in scientific literature and technical standards and subsequently were sorted according to the elements to which they relate. The work contains the actual anthropometric dimensions, description of the interface elements with references to standards which relate to them. The study also shows an example of an optimized keyboard layout for machine tools and methods applicable to design the spatial layout of the workplace. In conclusion there is evaluate the state of currently available literature and technical standards.

Production technology for mechanical seal flanges
Stoklasa, Patrik ; Gregor, Lukáš (referee) ; Zemčík, Oskar (advisor)
The bachelor thesis deals with the current technological process of the mechanical seal flange production. It contains an analysis of all tool and material equipment, the process itself and it describes selected cutting conditions and measuring aids. Variant production of technology is also characterized here, where the applied changes are described and explained in order to achieve lower costs from an economic point of view. Both variants are finally compared and evaluated.

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.
