Control of packaging machine using Safety PLC
Žiak, Martin ; Novotný, Radek (referee) ; Štohl, Radek (advisor)
This thesis deals with a technology of continuous packaging machine in the beginning from the point of risk assessment and design of necessary measures to reduce the risk as much as it is possible. Here the HRN method was used to quantify every risk factor. Next part documents the implementation of the safety measures and the realization of the safety circuits by using Simatic S7–1500F safety PLC and Shared device functionality. Safety function which is realized in the Sinamics S120 drive is Safe Stop 1. Next, it describes the drive dimensioning and the principle of the drive control. Simotion PLC is discussed in more details and then is used as a motion control master. An approach to the configuration of camming synchronous operation is dealt with in details. Cam design and their realization is documented, too. The thesis also demonstrates the state manager that was implemented in the user program and which is used according to the concept of OMAC state manager. In the end a simple HMI for packaging machine control is described.
The device for measuring of camshafts timings
Jozíf, Lukáš ; Mazal, Pavel (referee) ; Mazůrek, Ivan (advisor)
Bachelor’s thesis is focused on constructional concept of device for measuring of camshafts timing and its wear-out. After short introduction and definitions of basic concepts there are problems of cams design analyzed and overview of the commercially offered devices is mentioned. Next part focuses on construction of the proper device including design documentation. Procedure of measuring with the device and example of some data evaluation is described. In the conclusion I evaluated constructional and economic aspect the whole concept.
Link layer LAN network security
Sedláček, Jiří ; Grenar, David (referee) ; Slavíček, Karel (advisor)
The bachelor‘s thesis is about security concerning local area networks of the data link layer. The goal of the thesis is to characterize basic functioning of the ISO/OSI reference model as well as describing how the data link layer works to understand the topic, specify the possibilities of attacking the data link layer (for example rogue DHCP server, ARP spoofing, CAM table overflow, attacking the spanning tree protocol and others) and possible security measures to protect against the attacks. The purpose of the thesis is also a suggestion for assembling an experimental network relating to the topic of the thesis. Theoretical part determines the most important protocols of the data link layer, methods of abusing them and protection of those protocols. The practical part contains a brief description of the attacks, used utilities for accomplishing the attacks, a network topology, execution of the attacks, detection and protection against the attacks as well as briefly summarizing the results. The thesis also sums up some of the possible recommended configuration to repel the attacks and suggesting how to behave in a cyber environment. For the purpose of simulating the attacks, Kali Linux and Windows 10 are the operating systems that were used the most in this thesis.
Application of CAD/CAM technology for design and manufacture of a prototype of pitman front wheel
Bardoň, Václav ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
This master's thesis deals with design and manufacture of a prototype of pitman front right wheel of student's formula Dragon 4 of a team TU Brno Racing with use of advanced CAD/CAM technology. Opening part of the thesis deals with the theoretical analysis of milling technology. Furthermore, there is an analysis of aluminum alloys, which aims to integrate the material being machined CERTAL. In the practical part of the work the construction of pitman is done using CAD software SolidWorks 2012 and proposal of milling strategies is done using software PowerMILL CAM 10. The following is the realization of manufacture in CNC machining center MCV 754 QUICK at Bosch Diesel Ltd, in Jihlava. Techno-economic evaluation of the manufacture is done in conclusion.
CNC Mill Control System
Hájek, Luděk ; Jirgl, Miroslav (referee) ; Arm, Jakub (advisor)
This Bachelor thesis deals with designing construction and control system of 3-axis hobby CNC router using LinuxCNC. All axes are driven by Microcon SX 24-2341 stepper motors, which are provided with power from Leadshine M542 stepper drivers. LinuxCNC is installed on real-time PC with Ubuntu 12.04.5 LTS and it is connected with drivers via breakout board. CAD/CAM software Autodest Fusion 360 is used for graphical designing of final product, creating toolpaths and generating G-code. The Bachalors thesis contains research of construction elements, possibilities of CNC controlling, calculation and selection of suitable motors, design and documentation of CNC control system including documentation of all settings of LinuxCNC and CAM part of Fusion 360 as well as example of final product, created using this CNC router.

Automated machining in CAM systems
Jelínek, Tomáš ; Sliwková, Petra (referee) ; Zouhar, Jan (advisor)
This thesis focuses on the possibilities of machining using CAM systems automation. For modeling components such as holders, clamps and sample parts was used software CATIA V5R20 by Dassault Systmes. These samples were subsequently used to demonstrate the automation capabilities in PowerMill Ultimate 2022 by Autodesk. The automation program is consists of created tool database, templates with machining strategy and developed macros. A technical and economic evaluation was performed by comparing programming times of the program with and without using of the created elements of automation.
Design of a dynamometer holder for a turning center
Vystrčil, Ondřej ; Zemčík, Oskar (referee) ; Kolomý, Štěpán (advisor)
This thesis summarizes the possibilities of measuring the load on cutting during turning, the operational principle, and the requirements for operating the Kistler 9257B dynamometer. Within this study, several conceptual designs of the dynamometer holder for the SP 280 SY CNC turning centre were proposed. The best design was selected based on spatial considerations and collisions with the machine. The construction of individual components of the selected holder design was resolved. Necessary calculations and simulations for the safe operation of the holder were also performed. Based on the 3D model, CNC machine programs were created for machining the individual parts. Subsequently, the designed holder was manufactured and tested in the device. No deviations were found during the tests compared to the normal operation of the machine without the dynamometer holder.
