The influence of process liquids on the machining process
Lišková, Tereza ; Strejček, Jan (referee) ; Kalivoda, Milan (advisor)
The content of my study is related to the coolant comparison in machining manufacturing process. Subject of analysis is a company which produce vacuum pumps and machine parts from aluminium castings and billets. My records and final analysis are a recommendation of the suitable coolant for the manufacturing process in terms of their Lean production system´s KPI´s (Safety, Quality, Delivery and Costs).

Theoretical design of the steel production hall
Ratica, Filip ; Strejček, Jan (referee) ; Kalivoda, Milan (advisor)
The bachelor´s thesis contains a summary of the steel structural types of the halls and the principles of designing the steel supporting structure of the hall building. The thesis deals with the design of the layout of the hall, the individual elements of the structure, such as columns, purlins, trusses, crane runway and also roof and perimeter cladding. Furthermore, the thesis contains machining and other processes in the production of steel structural elements of the hall. And finally, the technical and economic requirements and costs of the construction of the steel hall are evaluated.

Development stages in CNC machining
Dlouhý, Vít ; Strejček, Jan (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with machining with the use of CNC machines. In the introductory part is outlined a brief historical development of these machines. The following are characteristics associated with machining processes. In the next chapter it is described for machining on the classic conventional machine tools. Followed by the entry of computer technology into the field of machining and its impact. The last theoretical chapter summarizes the capabilities of the current machines CNC machine tools. In the final part is a description of the production of the selected rotational components produced by using CNC lathe.

Lean project management
Vrba, Vojtěch ; Štroner, Marek (referee) ; Strejček, Jan (advisor)
The bachelor thesis deals with the topic of lean project management. It is divided into four main parts. The opening one deals with general principles of project management. The second part includes a list of and a brief description of individual losses within the field. The remaining parts join managers’ practical knowledge with information from reference books. The conclusion contains a custom form which is a basis for an analysis of project work in a company that carries it out. An improvement suggestion follows.

Proposal or the new layout of the "toolshop"
Varhaník, Matúš ; Zahradníček, Radim (referee) ; Strejček, Jan (advisor)
The aim of this work was creating the draft of stamping tool workshop layout. Our first task was to define the product range. Afterwards we were able to identify the technological and machinery equipment necessary for the execution of orders. The paper further discusses the need of human resources as well as the needs of the production, administrative and social areas. We propose possible technological solutions considering the range of production, the amount of machinery and personnel capacities. The next step is to optimize the layout, using tools such as material flow and continuity of operations. Not only safety at work but also the ergonomics of the proposed workplace is important for the final draft. The result of our project is to develop the final layout of stamping tool workshop containing the economic evaluation of the investment plan.
