The diploma thesis is based on a problem in which it was necessary to plan the geometry
of the forging and the technological process of hot bulk forging and trimming for a given
final product. The evaluation of the technological process was carried out with the help of
QForm UK Cloud 10.2.0 software, which enables simulations of various forming
processes. The problem was treated as 2D axisymmetric. The existing solution to the
problem presented the starting point of the diploma thesis, in which a detailed analysis of
the existing solution and further optimization of the geometry of the forging and the
forging process was carried out in accordance to the instructions of the thesis.
The result of the diploma thesis is an improved geometry of the forging with reasonable
consideration of the influence of thermal expansion. The material efficiency of the
presented technological process is 81.4%. The correction of the initial dimensions of the
blank, a more appropriate choice of lubricant, raising the initial temperature of the blank
and the use of compound tools significantly contributed to the improvement of the forging
process.
