This thesis researches the usefulness of laser cutting when threading holes with tapping
drills. The alternative approach with the use of laser cutting the holes instead of drilling
them, would represent a possibility for a faster and more efficient production processes and
lesser expenses for both material and labour.
In the first part, both laser cutting and hole threading processes are explained. In the next
part, the influence of cutting parameters on quality of cut holes is reserached, and finally, in
the last part of the thesis, results of the experiments are displayed and analyzed. That includes
the dimensional tolerances of cut holes, wear of threading taps, and economical analysis of
both methods of threading holes.
