Abstract

CNC stroje se uporablja za različne namene, kot so graviranje, rezkanje, vrtanje in 3D tisk. CNC stroje za obdelovanje mehkih materialov je možno sestaviti v samogradnji za relativno nizko ceno. Poceni sestavni deli so namreč dostopni prek spleta, pri izdelavi pa se lahko zgleduje po obstoječih odprtokodnih projektih. V diplomski nalogi sta predstavljena razvoj in izdelava nizkocenovnega CNC gravirnega stroja za graviranje mehkih materialov. V sklopu razvoja je bil stroj skonstruiran, pri čemer ohišje stroja temelji na aluminijastih profilih in lasersko izrezanih aluminijastih elementih. Krmiljenje CNC stroja je bilo razvito na osnovi odprtokodnega programskega paketa grbl, ki za ustvarjanje krmilnih signalov uporablja Arduino mikrokrmilnik. Po izdelavi in umeritvi stroja je zasnovan avtomatiziran proces generiranja G-kode iz rastrskih binarnih slikovnih datotek. Prikazani so rezultati merjenja natančnosti CNC stroja, način optimizacije parametrov programa za generiranje G-kode ter analiza stroškov celotnega projekta.

Secondary title:	Development and production of a low-cost CNC engraving machine-tool
Secondary abstract:	CNC machines are used for applications such as engraving, milling, drilling and 3D printing. CNC machines for soft materials can be assembled in self-construction for a relatively low price. Cheap components are available online, and one can use various open source projects during production. The thesis presents the development and production of a low-cost CNC engraving machine-tool for engraving soft materials. In its development, the machine has been designed with the housing based on aluminium profiles and laser-cut aluminium elements. The control of the CNC machine was developed on the basis of an open source software package grbl, which uses an Arduino microcontroller to generate control signals. After fabrication and calibration of the machine, an automated process for generating G-code from raster binary image files is designed. The results of measuring the accuracy of the CNC machine, the method of optimizing the parameters of the program for generating the G-code and the cost analysis of the entire project are presented.
