Finishing tool manufacturing
Rušín, Filip ; Kouřil, Karel (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with the production of a finishing instrument for roughing three different diameters. The first chapter introduces the selection of the required material, the semi-finished product design and the heat treatment of the product. The following is determination of the production conditions and compilation of the technological process and drawing. At the end of this work there is an evaluation of the technical-economic aspect and a discussion about possible upcoming situations.

Cutting and non-cutting operations
Hordějčuk, Jakub ; Dvořáková, Jana (referee) ; Dvořák, Jaromír (advisor)
Creating of any part may be by many ways, the choice of a particular method depends on many factors. The point of my bachelor's thesis is to present the currently most commonly used method of metal cutting. Gradually I introduces the most popular method of the metal cutting, the principles and usability. The first part is a presentation of theories and methods of cutting operations and the second one of a method non-cutting operations. To the different methods there are examples from practice.

Optimisation of machining process for an industrial application and a CNC machining centre
Soukupová, Veronika ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
Tato diplomová práce byla vypracována v průmyslovém kontextu, během stáže ve firmě Metso. Zlepšení obráběcího procesu zajišťovacích šroubů bylo cílem této práce, aby byla umožněna budoucí automatizace zakládání obrobku do stroje. Zlepšení bylo zhodnoceno na základě úrovně autonomie během obrábění, eliminace neprogramovaných zastavení stroje operátorem a dostačujícího odvodu třísek. Implementace automatických systému do číslicově řízeného obráběcího centra umožňuje zvýšení produktivity. Před automatizováním obráběcího procesu však musí být proces optimalizován. Zejména dostatečná fragmentace třísek a jejich evakuace jsou klíčové. Dlouhé nedělené třísky můžou poškodit systémy jako například automatický měnič nástrojů, dopravník třísek nebo průmyslového robota. Dostatečná lámavost třísek může být zaručena správným výběrem technologie a strategie obrábění, výběrem řezného nástroje a řezných podmínek pro daný materiál obrobku.

Production of screw-thread in small engineering company.
Straka, Jiří ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
This work, wrought in branch of engineering technology in terms of baccalaureate studies, mentions the basic type partitioning of screw threads and their screw-threads labelling. There are presented some possibilities of screw threads manufacturing by chip-forming operation and by chipless machining operation, both with using of appropriate tools. Further the methods of production used in small machine-works are described. In this case the small machine-works is represented by secondary technical school.

The Study of Economics of Tooling Technology
Ondrášek, Dušan ; Humár, Anton (referee) ; Jurová, Marie (advisor)
The aim of this diploma thesis addresses issues related to obtaining methodology for the production manager´s decision-making process in the field of technology selection, suitable tooling and cutting tools selection for a specific order or particular production plan. Evaluation of the manufacturing process while taking into consideration complexion of process controlling and contexture to the economy of this process. Analysis and evaluation of technological and economical aspects of a manufacturing process of the CNC chip machining in a real environment is targeted on the field of tooling, its selection, purchase, economy and consumption. The process controlling of technology is based on this analysis as well as the formulation of measuring by economic indicators such as economy, productivity, profitability etc. The analysis of important factors and parameters of this process demonstrated an influence on economy of the company. Several model cases have been created from the company records and from the provided research, the output of which became a basic methodology. The output of the analysis indicates possible directions of a management decision making. Thanks to a complex technical-economic view this thesis can serve as a methodological instrument for decision makers in the field of technology and cutting tool selections as well as an economy of production process improvement.

Manufacture of a fork for automatic tool changing of CNC machines
Dvořák, David ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This bachelor's thesis deals with the manufacturing of tool change forks from the tool magazine of Mikron 1150U. By this method several pieces would be produced for Chotěbořské strojírny a.s. due to save money. At first fork would be introduced and economic point of view, then this thesis would be focus to production of a 3D model,compilation of a technological procedure and manufacturing trial piece. Manufactruing is made by 3-axis machining centre Mikron VCP800. In the end the trial part would be checked and evaluated.
