Development of a prototype optical measuring device for tool geometry control according to the concept of open source hardware and software

U ovom radu se izradio prototip kojim je moguće mjeriti neke bitne značajke oštrice kao što su kutovi, zatupljenje i sl. Prilikom izrade koristio se koncept hardvera i softvera otvorenog koda te se na kraju dobio zadovoljavajući proizvod, uzevši u obzir potrebe za koje će se koristiti. Konstrukcija prototipa može ostvarivati gibanje u sve tri prostorne dimenzije, a gibanje se ostvaruje pomoću koračnih motora. Upravljački program pisao se u programskom jeziku Pythonu, a mikroprocesor kojim su se upravljali motori bio je Raspberry Pi 3 model B. Većina dijelova prototipa printala se na 3D printeru, dok su ostali kupljeni ili preuzeti od starih nekorištenih proizvoda.In this paper, a prototype was made to measure some essential blades features such as angles, sharpness, etc. The concept of open source hardware and software was used when developing, and eventually a satisfactory product was obtained, taking into account the needs that will be used for . The construction of the prototype can achieve motion in all three spatial dimensions, and the motion is achieved by stepper motor. The control script was written in Python programming language, and the microprocessor for controling the motors was Raspberry Pi 3 model B. Most parts of the prototype were printed on a 3D printer, while the rest were purchased or took from the old unused products
