Heidenhain tools for programming of CNC machines
Farka, Jan ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
Modern machine tools are equipped with control systems, which are the imaginary brain of the whole machine. These control systems are developed, further managed, and constantly innovated by many companies, so it is clear that there is a kind of competition in the field of control systems. The aim of this work is mainly to describe the possibilities of one of the greats among developers of control systems from the company Heidenhain and also a thorough comparison of this system with systems from other manufacturers. Last but not least, other Heidenhain products and their possibility of use in practice will be presented in the work.
Sinumerik Operate tools for programming of CNC machines
Krejčík, Jan ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The diploma thesis is focused on possibilities of spline approximation and interpolation of CAD imported by CAD Reader to control system. First chapter describes mathematical meaning of curves, the second chapter shows possibilities of approximation and interpolation in control system Sinumerik 840D and the third chapter applies these possibilities on practical example.
Efficiency Improvement Proposal of Production of Engineering Component
Nonn, Vilém ; Sliwková, Petra (referee) ; Sedlák, Josef (advisor)
This thesis deals with the efficiency improvement proposal of production of engineering component for agricultural machine. Firstly, the current production proces is described including description of the component and determination of manufacture times. The next part contains efficiency improvement proposal of production including determination of manufacture times. The last chapter contains a comparison of both variants in terms of production costs. The final provision summarizes results which were achieved and overall benefits of the thesis.
A proposal of production technology of a specified rotary part
Urbánek, Michal ; Dvořák, Jaromír (referee) ; Sliwková, Petra (advisor)
This bachelor's thesis deals with the design of a rotating part, processing of production documentation, including the tools choice, the method of workpiece clamping in the machine-tool and CNC lathes programming, counting the programme for the solved part.
Technical preparation for the production of label carriers and RFID inlays
Blažek, David ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
This bachelor thesis deals with the development and production of end effectors for the transmission of labels and RFID inlays using robots. The first part of it describes the RFID technology, robots and their end effectors, then compares the materials for the design of the end effector and its subsequent production. Then follows the preparation of a practical implementation, where the analyses examining the channels inside the effector are described. Furthermore, this work describes the testing of suction cups, production control by graphical simulation, production of individual prototypes of end effectors and their testing.
Machining of hardened parts
Heiserová, Sofia ; Sliwková, Petra (referee) ; Polzer, Aleš (advisor)
The usage of quenched materials in industrial production leads to the application of hard machining. Higher requirements for machines and cutting tools are needed during hard machining than during conventional machining. Quenched materials carry problem of volume and geometric changes after quenching and after machining as well. It is necessary to think about volumetric compensation in advance, before quenching of the workpiece. An experiment is suggested for optimalisation of longitudinal turning of steels 42CrMo4 and 50CrMo4. Hard turning has notable benefits such as flexibility of cutting tools and elimination of coolants, which provides ecological benefits. However, the disadvantages are higher tool wear and high prices of tools.
Analysis of cutting insert performance when machining of a titanium alloy
Fasora, Jan ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
This bachelor thesis is divided into two parts. The theoretical part deals with machinability of titanium alloys, cutting performance and wear of indexable cutting inserts (ICO) when turning. The experimental and very basic part of the work is presented with experiments in several series, where the cutting ability and wear of the selected inserts are assessed. Apart of some other measurements the results are justified with 3D measuring device and a scanning electron microscope analyses.
Optimisation of machining process for an industrial application and a CNC machining centre
Soukupová, Veronika ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
Tato diplomová práce byla vypracována v průmyslovém kontextu, během stáže ve firmě Metso. Zlepšení obráběcího procesu zajišťovacích šroubů bylo cílem této práce, aby byla umožněna budoucí automatizace zakládání obrobku do stroje. Zlepšení bylo zhodnoceno na základě úrovně autonomie během obrábění, eliminace neprogramovaných zastavení stroje operátorem a dostačujícího odvodu třísek. Implementace automatických systému do číslicově řízeného obráběcího centra umožňuje zvýšení produktivity. Před automatizováním obráběcího procesu však musí být proces optimalizován. Zejména dostatečná fragmentace třísek a jejich evakuace jsou klíčové. Dlouhé nedělené třísky můžou poškodit systémy jako například automatický měnič nástrojů, dopravník třísek nebo průmyslového robota. Dostatečná lámavost třísek může být zaručena správným výběrem technologie a strategie obrábění, výběrem řezného nástroje a řezných podmínek pro daný materiál obrobku.
Technology for a selected part
Pavliš, Jan ; Dvořák, Jaromír (referee) ; Sliwková, Petra (advisor)
The thesis convey the information about creation of technology for the production of a part assigned by the company Frentech Aerospace s.r.o. The teoretical part is focused on analysis to problematic of machining. The practical part describes production of given part now and proposal new production plan also with tool management. The conclusion of thesis is devoted to economical evaluation of both production plans.
Advanced methods of surface topography evaluation for finishing technology
Adamus, Petr ; Sliwková, Petra (referee) ; Píška, Miroslav (advisor)
The main theme of this thesis is the surface topography evaluation. The theoretical part introduces the fundamental methods of evaluation, measuring instruments and describes profile and surface topographic parameters. In the practical part, the influence of different cutting conditions in high-feed face milling was researched on sample made of aluminium alloy 7475-T7351. For the surface topography evaluation of all samples the measuring device Alicona IF G5 was used. The last part of the diploma thesis is devoted to the economic influence of cutting conditions on the process of high-feed face milling.
