A Proposal and Optimization of Cutting Conditions for Turning of a Cemented Workpiece
Heiserová, Sofia ; Sedlák, Josef (referee) ; Kouřil, Karel (advisor)
This final thesis is aimed at optimalisation of hard turning process of cemented workpiece. First part is focused on the study of factors of hard turning. In the second part the work deals with the proposal and conduction of experiments of new cutting parameters in chosen factory. The durability of cutting edges is monitored. This monitoring is based on the evolution of roughness of machined workpieces. Based on the data evaluation, the best cutting edge is selected and used for final optimalisation experiments. Production cost of operational section is calculated for each alternative of cutting parameters in the third part of the thesis. Possible savings were calculated based on the number of machined pieces per year for the cutting edge that was found to have the best results.

Finishing tool manufacturing
Rušín, Filip ; Kouřil, Karel (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with the production of a finishing instrument for roughing three different diameters. The first chapter introduces the selection of the required material, the semi-finished product design and the heat treatment of the product. The following is determination of the production conditions and compilation of the technological process and drawing. At the end of this work there is an evaluation of the technical-economic aspect and a discussion about possible upcoming situations.

The Study of Productions Operation Management
Petřek, Martin ; Kouřil, Karel (referee) ; Jurová, Marie (advisor)
The thesis dwells about methodics of processing an order in the company: Hardening shop Frydrych s.r.o. while respecting all the demands on the technological process of thermal and thermo-chemical manipulation as annealing, tempering and cementing. On the bases of the analyse and documental procedures the thesis is unraveling a concept for elimination of absences in the sphere of processing the order also as booking, invoicing and evaluating.

Production of Preparation Prototype Using Additive Method of Fused Deposition Modelling
Sedláček, Milan ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
This thesis focuses on the production of a product using the increasingly popular additive technologies Rapid Prototyping. The theoretical section explained the very rapid prototyping technology and its application in various sectors. There were also mentioned different materials to use for 3D printing and actual printing method. The practical part was focused on the prototype modeling in SolidWorks CAD software and the subsequent production of elements of the 3D printer uPrint, using additive method Fused Deposition Modeling. In the conclusion, there is the evaluation of prototype production and also cost comparison using alternative materials.
