Naprava CNC za vrtanje tiskanih vezij

MLINAR, SANDI (author), Bulić, Patricio (mentor)

V diplomskem delu je predstavljen postopek za izdelavo računalniško krmiljene naprave CNC za vrtanje tiskanih vezij. Predstavljena je realizacija strojnega dela naprave, uporabljeni materiali in postopki izdelave. Za premike obdelovalnega orodja uporabljamo koračne motorje, ki nam omogočajo želeno preciznost premika. Zaradi mehanskih premikov stroja so na samem ogrodju naprave varovalna končna stikala, ki ustavijo delovanje naprave v primeru napak. Napravo krmili mikrokrmilnik STM32F407 z nameščenim operacijskim sistemom za delo v realnem času FreeRTOS. Napravo krmilimo s programom, ki smo ga napisali v C# programskem jeziku z uporabo .NET ogrodja. Program omogoča uporabniku popoln nadzor nad napravo, avtomatsko ali ročno krmiljenje posameznih osi ter uvoz koordinat vrtanja iz programa Sprint-Layout. Program s krmilnikom komunicira preko vmesnika USART (angl. Universal Synchronous Asynchronous Receiver Transmitter), za sporazumevanje pa uporabljata predefinirane ukaze.

Abstract

This thesis presents a method for producing a computer controlled CNC device for drilling printed circuit boards. The presented work is the realization of machine equipment, materials and manufacturing processes. Stepper motors are used for moving machining tool, which allow us to achieve the desired precision. Due to the mechanical movements of the machine, end switches are installed which in case of error stops the device. The device is controlled by STM32F407 microcontroller running FreeRTOS operating system. The device is controlled by a program that was written in the C# programming language using the. NET Framework. The program allows the user complete control over the device, automatic or manual control of individual axes and the ability to import drilling coordinates from Sprint-Layout program. The program communicates with the controller over USART (Universal Synchronous synchronous Receiver Transmitter) interface and the prede_ned commands are used for communication.
