Abstract
Diplomski je rad posvećen praktičnoj izradi prototipa troosnog obradnog stroja. Osnovna mu je namjena trodimenzionalni ispis, a uz određene bi se modifikacije mogao koristiti i kao CNC obradni stroj ili rezač lima plazmom. Početna faza izrade započinje prenošenjem osmišljene ideje u CAD program SolidWorks, slijede odabir materijala i testiranja. Dijelovi su obradnog stroja izrađeni na glodalici GHK-2n tvrtke Prvomajska. Nakon slaganja mehaničke konstrukcije slijedi postavljanje aktuatora i mjernih osjetila potrebnih za rad troosnog obradnog stroja. Strojem upravlja mikroprocesorska platforma Arduino mega2560 temeljena na Atmelovoj ATmega256 seriji čipova. Postavljanjem izvornog koda u mikrokontrolersku platformu osigurana je veza između programske podrške i sklopovlja. Upravljačka elektronika DRV8825 tvrtke Texas Instruments zadužena je za upravljanje koračnim motorima u mikrokoračnom načinu rada. Objašnjene su prednosti i nedostaci toga rješenja jer izravno utječu na rad i upravljanje obradnim strojem. Regulacija temperature istiskivača plastike i grijane podloge ostvarena je PID regulatorom u zatvorenoj regulacijskoj petlji. Uređaj je umjeren i testiran, a ključne su komponente obradnog stroja pobliže objašnjene.
Abstract (english)
This thesis is dedicated to the practical development of a 3D machine tool prototype. The primary function is 3D printing and with certain modifications the machine could be used as a CNC milling machine or plasma cutter. The first phase of development is transferring the ideas into the CAD program SolidWorks, followed by the selection of materials and testing. The parts are then made on the milling machine GHK-2n manufactured by the company Prvomajska. After the assembly of the mechanical construction, follows the installation of sensors and actuators. The machine tool is controlled by Arduino's Mega 2560 microprocessor platform, based on the Atmel ATmega2560 chip. The relation between the sofware and the hardware is established by modifying the source code of the microprocessor. The microstepping motor control is provided by Texas Instruments' drivers DRV8825. The advantages and disadvantages of microstepping are explained,as is its impact on the way the machine tool works. A closed loop PID regulator is used for extruder and bed temperature regulation. The machine tool is calibrated and tested and all significant parts are explained in detail.
