Modern manufacturing trends in chip machining - turning, milling and driling
Moravčik, Jaroslav ; Trčka, Tomáš (referee) ; Polzer, Aleš (advisor)
Chip machining has strong historical foundation. First innovations in machining were created long ago and next Innovations appeared sporadically. The Industrial revolution and then the second half of 20th Century meant start of self–driven, programmable machines used in machining. This led interest of engineers to machining process itself. The aim of this Diploma thesis is to characterize most interesting modern trends from last few years and unite them in electronical database which will be included in this thesis. Main attention is aimed for innovations in chip machining in general and also in specific branches – turning, milling and drilling. Thesis also includes discussion about economical aspect of application of modern trends in chip machining.

Process Parameters Development for Producing of Lattice Structures Using 3D Metal Printing
Moravčik, Jaroslav ; Koutný, Daniel (referee) ; Vrána, Radek (advisor)
Selective laser melting (SLM) belongs to additive technologies. Progressive adding of layers of material powder and creating the structure with laser beam allows to create components with complex shapes, for example microstructures. This thesis explores potential of new printing strategies, which could lead to good melting of printed component and reaching to better structure without porosities. Based on analysis of actual state, software for calculation of laser trajectory was made with use of new printing strategy. Also, process parameters obtained from technical articles and from experiments made on Institute of Machine and Industrial Design on Faculty of Mechanical Engineering BUT in Brno were compared. This comparison led to suggestion of test set of components with new parameters and strategies. This set could lead to new researches in this issue.
