Design of a fixture for machining a car air conditioning component
Šetek, Tomáš ; Jeniš, Filip (referee) ; Svoboda, Petr (advisor)
The bachelor thesis deals with the design of the fixture. Clamping jigs enable fast and high quality production of components in the ever increasing demand of machined blanks on CNC machining centres. The aim of this thesis was to design a milling jig for an automotive compressor component with respect to minimum manufacturing cost, simplicity of design and reduction in machine time. The output of the work is the selected design prepared in the form of drawings. The work includes a review of design principles in jig design, commercially available fixtures, CNC milling machines and rotary or tilting tables that serve as additional axes of CNC milling machines.

Design of a group milling fixture for clamping components
Kalous, Jan ; Dvořák, Jaromír (referee) ; Zemčík, Oskar (advisor)
The thesis deals with the design of a group milling jig for four different shaped components. These parts are components of a baking line and are designed to clamp baking matrices for wafer production. The semi-product for all the parts is a casting made of EN-GJS-400-15, cast iron with spheroidal graphite. Machining on a horizontal milling centre MS NH5000 DCG from DMG Mori Czech s.r.o. was chosen to produce all four parts. A list of tools and gauges was made. Subsequently, a technological process was created for the selected part with the designation HAAC-62836-001. Then the cutting forces from the individual cutter inserts, clamping, and friction forces were calculated to verify that the machined piece could move in the jigs. This thesis includes calculations of both jigs and evaluation according to the technical aspect.

Design of clamping device for CNC milling machine
Kašpárek, Jan ; Dočkal, Kryštof (referee) ; Svoboda, Petr (advisor)
The bachelor thesis deals with clamping fixtures problematics for parts with difficult shapes. It aims to design an effective way of clamping of a part machined on CNC machining centre. The output is an adjustment of commercially available clamping system to suit requirements of assignment. The efficiency of the manufacturing process is determined by machining time calculations that showed that series will be finished in required time. Besides that, the thesis provides an overview in various fields, such as used materials in automotive industry, used machining centres in automotive industry and also the overview in principles of clamping.

Design for Production of Clamping System
Tuza, Marek ; Zemčík, Oskar (referee) ; Sedlák, Josef (advisor)
This bachelor thesis deals with the development of a universal clamping system, which should be part of every home workshop. However, it is primarily intended for drilling operations. The theoretical part presents research on various types of clamping devices. This knowledge is later used in the practical part. The aim of this thesis was to create a design of the clamping system, to perform its complete production and to evaluate its features both from a technical and economic point of view. The output of this bachelor thesis is an entire universal clamping system and its detailed drawing documentation. Moreover, there are also suggested further developments and improvements. Even though the production of the clamping system itself appears to be economically disadvantageous in comparison with a commonly available clamping device, it is necessary in order to meet specific requirements. In conclusion, the overall evaluation of the production of the clamping system is given.

Design of clamping device for machining of manifold part
Foltýn, Jan ; Mazal, Pavel (referee) ; Svoboda, Petr (advisor)
This thesis deals with clamping fixtures. It aims to design an effective clamping solution for machining parts on a milling machine. The clamping solution was designed and then verified by a series of calculations. The main goal and partial objectives were fulfilled. The output is the design of fixture, which can clamp given part. Subsequently, based on the calculations it was decided to use four of these fixtures on one machining table. When calculating the appropriate variation of the fixture layout, an estimate of the time required for the operations performed by the machine operator was made. The thesis offers an overview of the materials used in the automotive industry. Furthermore, the study of clamps and clamping systems. It also touches the problem of optimizing manufacturing process and demand for ways to speed up the manufacturing process.

Construction and Manufacture of a Clamping Device
Okáč, Petr ; Sedlák, Josef (referee) ; Kalivoda, Milan (advisor)
The thesis deals with various aspects of the structure - manufacturing solutions fixture in terms of small manufacturing firm. In the thesis are discussed problems which the author of the thesis with small-scale production meets. A substantial part of the thesis is also made by comparation of the production of small series production and large series. Emphasis is placed on efficiency and economy of the entire production process.

Production technology of a specified part
Tříletý, Vlastimil ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This diploma thesis deals with the design of the technology of production of machine parts in the company Walter s.r.o. The theoretical part deals with the technological possibilities of part production, the classification of cast irons and their machining, selected machining technologies at CNC milling centres and cutting tools suitable for this production. In the practical part, some technological analysis is done on the basis of which machining equipment is available in the company's machine park. The clamping fixture and clamping forces are designed for fastening of the parts. An advanced manufacturing routine is worked out according to given technical drawings, including the costs evaluation.
