The influence of geometry and cutting tool parameters on residual stress during machining of the pressure containers
Berka, Martin ; Kouřil, Karel (referee) ; Strejček, Jan (advisor)
This thesis deals with the influence of changes in cutting parameters and tool geometry on residual stress inside the material. I examine the influence by deep drilling. Changing the cutting parameters concerns the alteration of the tool feed and the pressure of the coolant during the process. The influence of tool geometry is studied by using two different single edge cannon drills. The research was realized in cooperation with Bosch Diesel Ltd. The theoretical part includes a description of the injection system, in which a high-pressure container is contained. The high-pressure container was used to evaluate the influence of the cutting parameters and tool geometry on residual stress. Furthermore, the theoretical part deals with the deep drilling technology used and the theory of residual stresses. The practical part shows the measurement parameters and the corresponding results. In the conclusion of this thesis, a technical-economic evaluation of the measurement is conducted.
