Problematic of Fast Automatic Tool Change by Working Machinery
Pavlík, Jan ; Marek, Jiří (referee) ; Velíšek,, Karol (referee) ; Demeč, Peter (referee) ; Kolíbal, Zdeněk (advisor)
This dissertation thesis is focused on the problem of the Automatic Tool Change for milling centers, which is recently shown as a very current topic. The content of this work is to conduct a comprehensive research of various types of ATC depending on the type of machine, as well as research of the current tool interface relating closely with these problems. There was made a comprehensive analysis on the basis of data obtained by comprehensive research, from which both the main factors affecting this topic and the area dealed and developed by this work resulted. The most problematic area of machinery used nowdays for the Atomatic Tool Change was detected as manipulator provided the exchange between spindle and tool storage. Kinematic structure and design of individual elements affects very significantly the dynamics of the whole process of exchange of tools. Therefore, the work is focused on problematic of the manipulator. The main results of this thesis are constructional design of several types of manipulators, which were partly realized within the project 1.2.4 of Brno department of RCMT in the form of the testing stands. There was developed simulation models for selected types of manipulators which were verificated by measuring on the real stand. On the basis of abovementioned problem there was identified another key issue related not only to the exchange process but also with complex problem of service life of spindle. It is a grab force in the process of picking tools. The work outlines the possibilities for further research of these forces on the service file of spindle (especially on service life of bering groups of spindle).

The design of software modules to control automatic tool change
Habán, Tomáš ; Holub, Michal (referee) ; Bradáč, František (advisor)
The presented work is concerned in system of automatic tools change for machining centers. The theoretical part of this diploma work is about basic distribution. The following practical part includes mathematical description of testing stand of systems of automatic tools change STD – 25. In next step the dynamic model of this mechanism and model of servomotor is realized using simulating environment as Matlab/Simulink. The simulation of designed model of complete system is optimized in aspect of rate of change. The obtained values of servomotors performance are compared for various loads of exchange arm at the appropriate times of change. The last section briefly describes other possible alternative solution of similar dynamic systems using connection of software SolidWorks and NI LabView.
