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.

Solution cutting operation of cover part.
Loukota, David ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
Analysis of the typical flanged parts, constructional and functional appreciation of the single part, design of the semi-finished product and fastening of the semi-finished product, choice of machines, tools, gauges for individual operations and technological process design and time calculation of of individual operations. Economical appreciation deal with assesment of the number of machines and deal with their usage at the production, calculation of sizes process area and quantity of the workers. Final costs of tools are also solved.

Water jet cutting of material
Jáchym, Jan ; Fialová, Simona (referee) ; Habán, Vladimír (advisor)
This bachelor thesis describes principles developement and usage of high - speed water jets for cutting. In the first part, it features description water jet cutting technology and its application, basic parts of high pressure system and sorts of generators pressure. In the second part, it divides water jet according to discreteness in time and chemical constitution. In the third part, it deal with studies usage so - called pulse jets, especially at ultrasonically modulated ones. It is described mechanism rise and break up of modulated high - speed jet on individual pulses.

Industrial robot application in area machinning technology
Staněk, Michal ; Matějka, Petr (referee) ; Knoflíček, Radek (advisor)
This study analyzes the application of industrial robots and manipulators in the area of cutting. It portrays the evolution of this dynamic sector and its next possible advancement. It explains the basic categorization and division of industrial robots and manipulators (IRM). The author offers an overview of various applications of IRM, with typical examples of the correct use of different types in technological processes (turning, milling, grinding etc.) in order to effectively increase the production. The study also describes two robotized technological work sites that the author personally visited and documented in detail. This study is supposed to show the indisputable advantages of employing the automating elements into the mechanical engineering and to explain the basic concept of this industry.
