In the introductory part of the master thesis, the properties of aluminium and its alloys, the processes for machining holes, the definitions of surface quality and the design of experiments method are presented. With the design of experiments (DOE) method, the influence of back boring parameters on surface quality and process productivity was analyzed. The use of this method also determined the optimal values of back boring parameters for maximum productivity while still achieving the required surface quality. It was found that the angle of the PCD insert has the greatest impact. Here we are limited by the maximum angle that can be set on the tool with the current shape of the PCD insert. Spindle speed has the second largest impact. With the optimal values of back boring parameters, the material removal rate was increased by a factor of 3,63, significantly reducing the machining time of the observed surface.
