Software for efficient use of material in 2D machining
Švanda, Ondřej ; Šeda, Miloš (referee) ; Lang, Stanislav (advisor)
Tato práce si klade za cíl obeznámit čtenáře s 2D CNC obráběním a rozličnými metodami popisu a manipulace s dvojrozměrnými objekty. Poté je představen tzv. Nesting problém a jsou popsány různé metody přístupu k jeho vyřešení. Praktická část pokrývá implementaci vlastního nesting softwaru, jenž je schopný efektivně rozmístit nepravidelné tvary do nepravidelné ohraničené plochy. Na závěr je provedeno zhodnocení řečeného softwaru a také je zmíněno jeho možné využití v praxi.

Study and comparison of CNC control systems
Nytra, Tomáš ; Vetiška, Jan (referee) ; Bradáč, František (advisor)
The goal of this bachelor’s thesis is to create research of state-of-art of implemented CNC cycles of controll systém. At first the basic problematice of programming numerical control with possibility of own programming. Then the thesis is focused on properties of control systems of companies Beckhoff and Siemens. There are analyzed functions of individual cycles, their features and parametrs, finished with mutual comparison. Ending of thesis is devoted to the development of a macro for two missing cycles of Bekchoff system.

Universal Cloud-Based 3D Print Slicer
Vejčík, Jakub ; Zbořil, František (referee) ; Kočí, Radek (advisor)
This bachelor thesis deals with the proposal and implementation of a cloud tool for preparation 3D models for 3D printing. 3D printing become a part of our lives and it is getting into schools, where it combines the digital world with the physical world. Nowadays schools have not sufficient computational power to handle demanding 3D models for 3D printing. This ascertainment has led me to create a cloud tool, because cloud provides sufficient computational power and it can be shared beetween multiple users at the same time. The cloud tool solves the problem of insufficient power to translate 3D models to G-code, which understands 3D printer. Solution is done by letting the demanding computing logic on the cloud and user just edit model according to his ideas in the web interface of cloud tool.

CNC router for PCB
Gerják, Rastislav ; Vaculík, Sebastian (referee) ; Vyroubal, Petr (advisor)
In mechanical industry, both additive and subtractive manufacturing methods are controlled by instructions in G-code, making it possible to utilize both technologies in one modular device. Main objective is to design, construct, and calibrate multipurpose machine based on RepRap 3D printer, which will be able to use attached spindle to precisely mill light materials. Particular emphasis is given to ability to carve a pattern and drill holes in plated substrate in order to create functional PCB by incision.

Control of three-axis Cartesian manipulator
Drha, Štěpán ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
The bachelor thesis deals with the proposal and realisation of the control system of the universal Cartesian manipulator. The aim of the thesis is to create a functional control system of the manipulator with the usage of available hardware and software modules. The introduction of the work summarizes general issues of the Cartesian manipulators controlling. The following chapter occupies with the selection of the individual software and hardware modules of the control system. Based on these modules, the control system of the manipulator is designed and realised. The conclusion of the work evaluates the results and it proposes possible improvements for this application.

Control system design for robotic manipulator
Křivánek, Štěpán ; Andrš, Ondřej (referee) ; Houška, Pavel (advisor)
Main goal of this thesis is to design and realize software for controlling planar robotic manipulator “Mini-swing”. At the beginning, thesis describes general issues of this problem. Research part deals with dividing manipulators in groups by their kinematic configuration. Next part merely outlines usage of National Instruments module “Robotics”. “Mini-swing” manipulator and its kinematic are described in the following part. Design and realization of software for controlling Mini-swing’s ending effector are parsed in next part and at the very end of thesis you can find summarization of accomplished results.
