Abstract

Tema ovog rada bila je razvoj prototipa CNC prijenosnog plazma rezača i njegovog upravljačkog sustava. Stroj je modeliran primjenom CAD sustava SolidWorks. Zbog niskog budžeta i dimenzijskih ograničenja osmišljeni stroj ima mogućnost gibanja u 2D prostoru te polarnu kinematsku strukturu, što znači da ima dva posmična prigona od kojih je jedan linearni, a drugi rotacijski. Upravljački sustav sastoji se od mikrokontrolera baziranom na ESP32 integriranom krugu s upravljačkim softverom FluidNc, te koračnih motora s odgovarajućim regulatorima koji se koriste za pogon posmičnih prigona stroja. Tijekom rada provedeno je parametriranje upravljačkog sustava kao i testiranje posmičnih i glavnih prigona stroja. Rezultat ovog rada je funkcionalni prototip stroja s upravljačkim sustavom u čijem je softveru implementirana polarna kinematika.

Abstract (english)

This thesis deals with the development of a CNC portable plasma cutter and its control system. The machine was designed using the CAD system SolidWorks. Due to budget constraints and size limitations, the designed machine is capable of movement in a 2D space and features a polar kinematic structure. This means it has two feed drives, one linear and one rotary. The control system consists of a microcontroller based on the ESP32 integrated circuit, running the FluidNC software, and stepper motors with appropriate drivers used to power the machine’s feed drives. During the project, the control system was parameterized, and feed and main cutting tool of the machine were tested. As a result, a functional prototype was developed, with a control system with polar kinematics implemented in its software.
