Technology of the frame base production
Havliš, Lukáš ; Špaček, Jindřich (referee) ; Rumíšek, Pavel (advisor)
The bachelor's thesis deals with technological project of frame base production. Since a component designated as a wing base is produced together with this base, the thesis is also concerned with production of this part. Methods of sheet metal forming are analyzed in the theoretical part. Methods used during production pressings - such as cutting, bending, punching and calibrating – are concerned. Practical part of the thesis comprises description of produced segments and their location and function within the assembly, choice of material, shearing layout and choice of forming machine. Economic evaluation of segments production has been performed in conclusion. As soon as material has been chosen (11 343 material has been chosen with regard to low requirements for assemblies), calculation of cutting and bending force has followed. Forming machine (LE 250 has been found the most suitable one) has been chosen based on results of the necessary forming forces, after evaluation of cutting layout and demand on the sheet metal coil. Two options of components production have been compared in the economic evaluation. Method of production in a common tool has been found more cost-effective.

Simulated Verification of Complex Technology Project
Varjan, Matúš ; Hrubý, Jiří (referee) ; Lenort,, Radim (referee) ; Rumíšek, Pavel (advisor)
In the introduction, doctoral thesis as a complex technological project uses the summary title Stability of production. Stability of production is defined as a maintaining the required properties of the system over a given time period. Stability of production, based on the literature study included: – generally known systems and concepts, for example Process Stability, System Stability, Toyota Production System, Lean Manufacturing, etc. – less-known systems and concepts, for example Maintaining the fidelity of the production program, Stable order-sequence concept. The practical part of the doctoral thesis is focused on the less-known concept: Stable order-sequence. The task of the Stable order-sequence is to follow the sequence of orders given by the planned production program in the course of the production and at the end of production. Maintaining the sequence of the orders has a positive experience in the logistics activities between the final producer and its suppliers. As it was found by the planned experiment for a full factory plan, the sequence of orders in the material flow of original equipment manufacturer is influenced mainly by: – the cause of the removing orders from material flow, – the effect of the causes LIFO stack vs. branched material flow, – the effect of the causes LIFO stack vs. branched material flow vs. the removing from the material flow. By the analysis of Stable order-sequence, it was found that the methodology of the concept contains deficiencies. It does not state how to choose for example the size of the time period, time interval, data editing etc. By this lack, the subject can skew the results in the evaluation of the indicator PFT0 up to 4 %. Or by using of suitable adjustment, the value of the indicator PFT0 can be improved more than 50 %. To test the concept of a Stable order-sequence in practice has been designed technological project with the support of discrete-event simulation. It was about the implementation of new management logic to the stack behind the welding of original equipment manufacturer. The new logic of management was designed with an emphasis on Stable order-sequence concept, to arrange the orders in process according to the planned sequence. On the base of the functionality verification of the new stack logic, it was found that the logic affects the sequence of the orders, but not fundamentally. In tracking the hourly intervals for 25th calendar week 2013, the value of PFT0 was not improved in 37 cases, the value remains in 30 cases and the value was improved by the value of the median 18,68 % in 30 cases orders.
