Progress in technology of mold milling with coated profile tools
Doležel, Ondřej ; Bumbálek, Bohumil (referee) ; Píška, Miroslav (advisor)
This diploma thesis is involved in possible development of different types of milling molds coated with modern plows. The first part is devoted to an analysis of contemporary trends in forms production technology. The analysis includes the different types of machines and tools for making various kinds of molds and dies. Another part deals with design of dies for sheet metal shears. The thesis continues by design of the production procedure after heat treatment and finishing die by miling. For milling of die are designed miling tools, the NC program and the possible development of manufacturing the die using a new machining center and the possibility of production optimization. The penultimate point of the thesis is technical and economical evaluation of the direction of development and comparison of positives and negatoves of each method. At the final evaluation is all summed up.

Drop forging of pinion
Kameník, Tomáš ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
KAMENÍK Tomáš: Drop forging of pinion The project has been elaborated within the framework of studies of the subject B 2307 and it presents the lay-out of the technology of the forging – the pinion which is made as the drop forging from the material 14 220. The rougher and the finishing forging die were suggested on the bases of the literature study of the drop forging. In consideration of the big series /100 000 pieces/ and the calculated forging power /25MN/ the component will be made on the vertical forging press LZK 2500P/SH (the manufacturer ŠMERAL Brno a.s.). At the end of the thesis there are performed calculations of the technical and economic evaluation.

Drop forging of pinion
Cvrček, Jan ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
The final project has been elaborated in a frame of Bachelor’s studies branch Manufacturing technology assesses design of production pinion by method of die forging. The pinion is manufactured from alloyed structural steel 14 220 (1.7131). Size of production is set on 100 000 pieces per year. The pinion will be forged on the vertical forging press LMZ 1000 A with forming force 10 MN. The forging is formed in two operations. Forming tool is manufactured from alloyed instrumental steel 19 552 (1.2343). In the last chapter of the project is described the price comparison and costs for manufacture of die forging and machining.

Sinumerik tools for programming of CNC machine tool
Chytil, Tomáš ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
The bachelor thesis focuses on the usage of possible ways of the Sinumerik system for programming of the form of the drop forging. The first part of the thesis contains of the characteristics of the part and its function in the composition. In the second part there is all the proper visual documentation. The following parts of this piece of work is devoted to the history and specification of the Sinumerik control system and a suggestion on how to make a forging die.The next part is contributed to the possible ways of how to produce a form in the Sinumerik system. The final part deals with the very formation of the programme and its graphic simulation.

Assessment of suitability welding modes MIG PULSE and MIG DOUBLE PULSE for repairing of forging die
Sotolář, Vojtěch ; Kubíček, Jaroslav (referee) ; Izák, Josef (advisor)
The bachelor thesis is focused on the renovation of forging dies by pulse methods, specifically MIG pulse and MIG double pulse. The subject of this research was a part of forging die made of steel Wr.Nr 1.2343ESU (H11), however the problem was simplified to the welding of four prisms with the same type of material. The main goal was to evaluate whether these methods can be utilized to speed up the entire renovation process as the welding speed is its undeniable advantage. There were used two types of welding materials to assess the suitability of the renovation. For the tough weld was used the martensitic material CRONITEX RC 58 and for the interlayer was used austenitic-feritic material WELCO A1660. The assessment was conducted based on the non-destructive visual test and also based on destructive tests of macrostructure, microstructure and hardness measurement. The experiment results showed that configuration of tough material with interlayer is inappropriate. The most suitable process seems to be the welding of only tough layer without any interlayer.

Drop forging of pinion
Mikeš, Filip ; Žák, Ladislav ; Štroner, Marek
The project deals with the design of the requested part, with technology of volume thermoforming – drop forging. The literature study was written according to this technology and the design of pinions manufacture from steel 14 220 was made. On the basis of the calculated forging force, the molding machine LZK1000P/SH, from the company Šmeral Brno, a.s., and other necessary machines were chosen to manufacture the forged piece. According to chosen machines and calculated parameters, the manufacturing process, the drawing documentation and the technical – economic evaluation were compiled.
