Bulk forming technology of piston of disk brake
Kiza, Jakub ; Jopek, Miroslav (referee) ; Forejt, Milan (advisor)
The master’s thesis presents a proposal for the manufacturing technology of a disk brake piston made of material ČSN 41 2010 for a car brake caliper. Method of cold volume forming was chosen due to the production requirement of 200 000 parts per year, convenient axisymmetric shape of the part and required size tolerance. Based on study of chosen technology, production technique, which contains calibration and backward extrusion, was designed. Technological computations and optimalization of tool dimensions were done for the chosen production technique. The manufacturability of the part was verified by numerical simulation in Simufact Forming software. Because of unavailability of automatic cold forming machine designed for bigger sized parts on the market, the forming process is done by two forming tools with use of INWORK 700 hydraulic press. For the selected profit of 20 % the price for the part was set at 26,8 Kč. The turning point was determined as 52 745 pieces.

Metal formíng production of spring bush by cold extrusion.
Třeštík, Jakub ; Samek, Radko (referee) ; Forejt, Milan (advisor)
TŘEŠTÍK Jakub: Metal forming production of spring bush by cold extrusion. The Master’s degrese project, 2nd form, summer semester, academic year 2009/2010, educational group 5O/60, Mechanical Engineering – Manufacturing Technology, Brno University of Technology, Fakulty of Mechanical Engineering, Institute of Manufacturing Technology, Dept. Of Metal Forming and Plastic, May 2010. This project sloves the manufacturing proces sof “Spring bush” part by technology of cold extrusion. Part is made of 12 122.3 steel. Semifinished product has a cylinder shape with dimensions O29-24 mm. This part is made during four bulk forming operations on the TPZK 25 Šmeral Brno, a.s.

Contactless measurement of surface temperatures in mechanical engineering
Gorčica, Jakub ; Forejt, Miloslav (referee) ; Polzer, Aleš (advisor)
This diploma thesis is focused on the theory of contactless measurement of surface temperatures with thermovision camera Flir SC2000 and on the principles of imaging the camera is based on. The tablets and the applications making work with camera easier are processed in the Visual Basic in practical part. The stand for fine taking emissivity is compiled and described, and emissivity of different materials and different milling cutters is taken in this diploma thesis.
