Technology cutting on CNC machining centres
Martiňák, Marek ; Sedlák, Josef (referee) ; Prokop, Jaroslav (advisor)
The aim of this bachelor’s thesis is to prove the mastery of the fundamental principles of technological background processing for CNC machining center CW 800. After studying specialized literature and gaining practical experience while working on the machinery in question, a technological characteristics of machining centres has been compiled, including the technological parameters of the above mentioned CW 800. Based on the sample of a concrete product, a machining technological process of the given part has been designed, including the programme itself. This design can serve as a model sample for generally applicable processing of technological background with other parts as well, on the basis of the submitted drawing documentation.

Technological and economical aspects aplication CNC machining centers
Martiňák, Marek ; Osička, Karel (referee) ; Prokop, Jaroslav (advisor)
The Aim of this diploma thesis has been to analyse the application of the CNC machining centers for the production especially with concentration on accuracy and economical aspect of the machining process. After the study of the literature and making familiar with the production on the CNC machine tool of the type Deco Sigma 20 ( manufacturer, the firm Tornos ) it has been evaluated the technology of the design of the chosen part, its machining accuracy and found out the economical parameters of this machinery for this chosen part as a necessary supposition for securing the correct production in accordance with the requirements of the client. The described process of the technological and economical preparation for the production as well as its checking can be used in future for the proposals of the further similar parts.

Using measuring probes ( for tools and workpieces) for production machine of range of products firm TOS KUŘIM
Kohút, Josef ; Holub, Michal (referee) ; Opl, Miroslav (advisor)
The purpose of this dissertation is to familiarize the reader with basic recognition of machine measuring probes for tools and workpieces. Namely then in area of measurement on CNC machining centers. Both recognition from aspects of principle of function of sensing elements and type of transmition to control system, and recognition from constructional aspects are described here. Further it puts mind on equipment of machine probes (touches etc.) and rules for best selection of this equipment. Next part of this work describes selection of appropriate probes, for universal machines from production of firm TOS Kuřim. Last part deals with testing of designed measuring system for concrete machine from production of firm TOS Kuřim. His typical composition, evaluation of tests results and achieved accuracy is also described here.

Rationalisation of production technology
Konečný, Petr ; Kolář, Ladislav (referee) ; Osička, Karel (advisor)
This thesis deals with the rationalization of production technology of selected component. The first part contains a brief introduction of the company NTS Prometal Machining s.r.o. and brief description of the product. The following section is an analysis of existing manufacturing technology. The practical part is focusing on the proposal of rationalization versions of the production process. After evaluation of all possible options of rationalization there has been developed a new technological process with a respect to time and cost savings. Finally there was carried out economical evaluation and recommendation for further production of this component.

Production of Rotating Parts on a CNC Multifunctional Center
Turčín, Jiří ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with a design of technological solution for the production of a part named “Pulsation wheel” suited for a CNC machining center. Proposed technology consist of technological process and the choice of tools and measuring equipment. The production and necessary measurements are verified and carried out hands-on in a metalworking shop. This technology is compared with different options and variations used in this shop, whether machining on a different machine or different metal semi-finished work piece. This comparison is also described in technical-economic assessment.

Rationalization of production casing
Konečný, Jan ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
The thesis deals with the reorganization of production injection pump casing, when the existing production solution, using cutting lines, did not meet the requirements for flexible manufacturing. There are handled points leading to the replacement of the line of machining centres after a brief introduction of the company. Among the main points of thesis are the design of operations, choice of tools and cutting conditions, proposal clamping device and technology, techno-economic evaluation of the newly introduced production.

Optimalization of cutting process for machining of aluminium profile on CNC centre
Král, Ondřej ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
This master‘s thesis deals with the suggestion of suitable tools for milling aluminum alloys profiles for the construction of aperture fillings and their aplication to a CNC machining center for increasing the efficiency of the cutting process. The first part of the thesis is focused on the description of the company and the workplace of production of aluminum alloys constructions. The following pages contain description of standardized products, which are used to identify the test profile that is part of the experimental verification. Next part of this thesis is characteristic of aluminum alloys and tool materials suitable for their machining. Second part of this work contains an analysis of the current state, suggestion of new cutting tools and their application to the production proces. At the end of this thesis there is the technical-economic evaluation that deals with the time and economic savings of the applied design.
