Optimization of production steering shaft
Hlavinka, Martin ; Kalivoda, Milan (referee) ; Jaroš, Aleš (advisor)
Bachelor thesis deals with the creation of the optimal divided chip in the turning technology. The material for production of the steering shaft is steel C35RC suitable for forming and turning from which semi-finished products are produced at horizontally forming presses. They are machined at the production robotized line where the problem with the undivided chip arises. For the specified set of cutting conditions the uses the cutting tools which aren’t very suitable for the given types of technological operations. The recommended values of cutting conditions are different from the specified set of cutting conditions. The result will be choice of new-cutting tools for turning technological operations to shape short divided chip.

The production of the console deburring machines
Hlavinka, Martin ; Daněk, Ladislav (referee) ; Kubíček, Jaroslav (advisor)
This thesis submitted deals with the project of the change of the production of the semi-finished product of the console which is produced by casting from the cast iron ČSN 42 2420. The component forms the frame of the deburring machine with two electric motors with the gearbox. For the suggested production the method MAG of technology welding was chosen. Because of the given technology the new construction of the component was chosen. The welded product consists of eight parts burnt from heavy-walled sheet metals. The suggested material of the construction is steel S235JR and for welding the filler rod Weld G3Si1, diameter 1 mm is chosen. For the determination of the optimal parameters of welding the testing through the slap next to the skin weld (size a5) was made. Simultaneously with the testing the fracture areas and the weld root were examined. The suggested parameters of welding were used during the preparation of WPS. For the assembling of the component the operating schedule of welding is planned.
