Kurzbeschreibung (Abstract)
In drilling processes, selfexcited vibrations have a negative influence on the achievable drilling qualities and tool life. Lowfrequency radial vibrations are characterised by oscillating movements of the tool tip and the generation of lobed holes in drilling. This study focuses on the participation and influence of the land widths of twisted drilling tools on these vibrations. Therefore, drilling tools with different land widths and a lengthtodiameter ratio of 12 are used, and different parameters, such as feed rate, cutting speed, coolant pressure, prehole diameter, and chuck selection, are varied in a drillout process. The results show that the land widths have a statistically significant influence on the formation of lateral vibrations and the generation of lobed holes.
