Design of production technology for cone rotary mechanism
Knápek, Merlin ; Chladil, Josef (referee) ; Sliwková, Petra (advisor)
Bachelor's thesis is focused on design of production technology for protype of rotary bearing for children's excavator, which consists of conical pin and conical bushing. Specified production volume is 1 piece. Material was changed for both components to stainless steel AISI 303. From concidered technologies was chosen machining, specifically machining on conventional machines. Individual methods required for production were analyzed, including turning, milling, grinding, drilling and threading. Original design was modified so that only lathe and drilling machine have to be used for machining. Based on machines and chosen method were selected suitable tools, gauges and aids for production and was developed manufacturing process also acompanied by operational instructions.

Manufacturing processes of components with a minimum number of tools
Zábojník, Zdeněk ; Drbal, Martin (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis focuses on manufacturing components with a minimal number of tools on a CNC lathe. To demonstrate the production of components with a minimal number of tools, manufacturing procedures for two components, A and B, were designed. Component A is a typical component of simple shape that can be manufactured with a low number of tools. Component B is more complex in shape, and two production variants were proposed for it: one with a higher number of tools and one with a reduced number of tools. For both components were were selected tools, proposed manufacturing procedures and time calculations were carried out. In conclusion, a technical – economic evaluation and comparison of both variants for component B were conducted.

Rationalization of holder production
Šidlák, Jaromír ; Zemčík, Oskar (referee) ; Sliwková, Petra (advisor)
This thesis presents a proposal to replace the weldment of a mount with a workpiece. The mount is part of a designer light and 200 of them are manufactured every year. The mount material has been changed from stainless steel 1.4301 to aluminium alloy EN AW 6082. Design modifications have been made to the part to improve its functional properties and reduce machine time when it is made. A semi-finished product from a cold-pressed and drawn round bar according to ČSN EN 755 – 1 was determined and its size was calculated. The degree of material usage was then determined, as was consumption of the material for the year’s production, which amounts to 6 bars 3 metres long. Machinery from the company’s portfolio was proposed for the modified part. The majority of the part is produced on a KL 285 CNC turning centre. Appropriate machining tools were chosen for the selected machines. The work includes the complete technological production process as well as the CNC programs for machining the part. They were created directly at the machine using the Sinumerik 828D control system, specifically its Shopturn superstructure. After debugging the program, the necessary machining tools were placed as appropriate in the machine. Prototypes were then made to verify that the technology was designed correctly and that the parts were manufacturable.

Proposal for rationalization of production technology of a bronze part
Konůpka, Tomáš ; Kolomý, Štěpán (referee) ; Sliwková, Petra (advisor)
The subject of this diploma thesis is a proposal for rationalization of production technology of part made of bronze material CuSn12. Firstly, the manufactured component and the current state of production, including machine times, are described in detail. In the following part, the manufacturing technologies used are described, including turning, drilling and milling. In the next part, the proposal of the production rationalization and the analysis of the time consumption of each operation is described in detail. The last part of the thesis deals with a technical-economic evaluation, including a comparison of the current and rationalised situation. Finally, the achieved objectives and the contribution of the proposal to practical application are summarized.

Design of production technology of an aluminum alloy flange
Vrbka, Tomáš ; Chladil, Josef (referee) ; Sliwková, Petra (advisor)
This bachelor's thesis aims to create a technological procedure for producing a flange, including subsequent instructions and select suitable tools, gauges, and machine parameters necessary for its production. One piece of flange was produced. The material of the flange is aluminium alloy EN AW-2017A. The flange is part of the diesel pump and has the priority function of sealing and guiding the pump camshaft. The flange was produced on a one machine DMG Mori CLX 450 universal CNC lathe on one clamping. To verify the functionality of the design, a 3D model of the flange was first created and printed. A technological procedure for producing the component was made, and a CNC program was created for the machine. Subsequently, the actual production of the part was carried out. For production, a rod with a diameter of 80 mm was used and fed to a length of 40 mm. Turning technology was used for machine the face, grooves, outer and inner contours. Milling was used for the recesses for the bolts and drilling was used for the holes. Iscar tools were selected for turning, and Hoffmann Group tools were chosen for milling and drilling. After production, the important dimensions were measured by using Mitutoyo and Bowers gauges and a Mahr roughness gauge.

Design of technology for gear manufacturing
Urbánek, Michal ; Píška, Miroslav (referee) ; Sliwková, Petra (advisor)
The master’s thesis is focused on the design of production technology and the choice of machines and tools to achieve the required accuracy according to the drawing documentation. During the design of production options, the advantages and disadvantages of gear machining variants were described. In the theoretical part, the technologies of the proposed operations were described, such as turning, milling of gears in a rolling method, shaving and grinding. In the practical part, the production itself is described in all sixteen operations that were needed to produce the part. Instructions and tables of measured dimensions were created for each machine operation. The economic evaluation summarizes material costs, machine and preparation times depending on the size of the production batch.

A technological preparation of the wiping plate production
Balhar, David ; Dvořáková, Jana (referee) ; Píška, Miroslav (advisor)
The main aim of this master's thesis is to propose a technological preparation of the wiping plate production. Elaboration is divided into four chapters. The first chapter describes forming tool (function and construction). In the second chapter is technologies overview, which are used for the wiping plate production. The most important is the third chapter, because it deals with the main output, and the actual proposal of technological preparation of the production. In the fourth chapter, production is reviewed economically.

Turning machines and tools, production of a sample part
Šaroun, Martin ; Jaroš, Aleš (referee) ; Kupčák, Radim (advisor)
This bachelor's thesis provides an overview of turning technology in the research part. It describes the basic terms and terms, deals with the division of lathes and turning knives. The practical part of the work is focused on the technological processing of the specified part, which is the assembly mandrel used for precise gluing. The technological process was developed and in cooperation with the company, the production of its own component took place. In the last phase, the final inspection of products and evaluation took place.
