Design of production technology of specified component for conditions of workshop at IME FME Brno university of technology
Novák, Lukáš ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
Diploma thesis deals with design and implementation of manufacturing technology of a part which was given by company Frentech Aerospace s.r.o. Manufacturing technology is prepared for conditions of workshop of Department of Machining FME Brno UT (laboratory C2). Acquired knowledges are used for design of innovative manufacturing technology with cutting tools from company Pramet Tools, s.r.o. Manufacturing technologies of gained part are designed for alloy blank EN AW 6082. Technical-economical assessment of all manufacturing technologies is part of this thesis. Both of manufacturing technologies designed for laboratory C2 are assessed together and manufacturing technology given by company Frentech Aerospace s.r.o. is assessed alone due to using different blank material.

A new production of the shaped shaft "Hohlwelle".
Kundrát, Vladimír ; Kouřil, Karel (referee) ; Píška, Miroslav (advisor)
Diplomová práca je zameraná na riešenie aktuálneho a akutného problému výroby tvarovej hriadele “Hohlwelle” vo firme Vekastool. Tri návrhy riešenia boli sústredené na dokončovaciu operáciu diery 30 H7, z ktorých dva boli priamo odtestované vo firme. Jedna z nich bola návrh a realizácia nového vyvrtávacieho nástroja firmou Ham-Final , ktorá priniesla zníženie nákladov o dve tretiny.

Technology cutting on CNC machining centres
Martiňák, Marek ; Sedlák, Josef (referee) ; Prokop, Jaroslav (advisor)
The aim of this bachelor’s thesis is to prove the mastery of the fundamental principles of technological background processing for CNC machining center CW 800. After studying specialized literature and gaining practical experience while working on the machinery in question, a technological characteristics of machining centres has been compiled, including the technological parameters of the above mentioned CW 800. Based on the sample of a concrete product, a machining technological process of the given part has been designed, including the programme itself. This design can serve as a model sample for generally applicable processing of technological background with other parts as well, on the basis of the submitted drawing documentation.
