Analysis of the surface after laser cutting
Narovec, David ; Sedlák, Josef (referee) ; Osička, Karel (advisor)
This diploma thesis discusses laser cutting and the consecutive surface treatment of cut parts. The theory of laser cutting is described in the first part of this thesis, including laser history and the laser emergence principle. Cut parameters and the influence of the laser cutting on the material are described later on. The next part describes the laser cutting technological possibilities and other laser technology utilization options are outlined. In the last theory part, metal surface treatment used in the experiment is covered. Coating thickness is evaluated in the practical part of this thesis, as well as roughness, microhardness, chemical microanalysis and metalography. The evaluation of the results achieved, and optimal surface treatment execution suggestions are addressed in the last part of this thesis.

Production forming drills and theier use in practice
Narovec, David ; Osička, Karel (referee) ; Dvořák, Milan (advisor)
The bachelor thesis deals with forming drills, their production and practical use. The forming technology with focus on the heating of the material for forming is described in the first part of the paper. The second part is focused on general drilling. The drilling technology, drilling process and various drill production techniques are covered. The twist drill is described as well and its basic parameters are mentioned. Twist forming drills are examined in the last part of the paper. Material choosing, technological drill forming process, final drill shape testing for its fading and practical utilization. In conclusion a practical study of cleft drill was performed.
