Secondary title:	Project of making computer-controlled lathe in teaching Design and technology
Secondary abstract:	The purpose of diploma thesis was to manufacture computer-controlled lathe, which could be compatible with hand wooden turning lathe. Procedure would be controlled by computer, coordinates for control of electro motor would be sent through microkontroller.. In the first part we present all the theory of the lathe and its interaction of lathe with the workpiece. The idea of computer-controlled lathe is a stand with leadscrew, caggiage and tailstock. Tailstock is moving in the axis (X,Y) and it is moved by stepper motor, computer-controlled through microcontroller. User manual has two forms, first is for the callibration of tailstock on the correct place, task of the second one is to load the data (coordinates) of shape of the finished project and making one as well. Computer-controlled lathe as an independant unite is too complex for appliance in the primary school, but when dismantled to individual segments, for example leadscrew, caggiage, stepper motor, user manual … it can be used as a pedagogical instrument on the primary school level.

Abstract (ePrints):	Namen diplomskega dela je bil izdelati računalniško krmiljena vodila za stružni nož, ki bi bila združljiva z ročno stružnico za les. Krmiljenja bi bila nadzorovano preko računalnika, koordinate za krmiljenje pa bi bile preko mikrokrmilnika poslane na elektromotorje, ki bi fizično premikali sani/stružni nož. V prvem delu so predstavljena vsa teoretična znanja, ki zavzemajo področje struženja in interakcijo stružnega noža z obdelovancem/obdelovano snovjo. Računalniško krmiljen stružni nož, ki sem si ga zamislil, je stojalo z vodili, sanmi in vpenjalom za stružni nož. Le-ta pa se giblje po dveh koordinatah (X,Y), ki jih premikamo z koračnimi motorji, računalniško krmiljenimi prek mikrokrmilnika. Uporabniški vmesnik (program) je sestavljen iz dveh zaslonskih mask; prva je namenjena namestitvi stružnega noža na želeno mesto, druga pa naložitvi podatkov (koordinat), oblike končnega izdelka in samemu struženju le-tega. Računalniško krmiljen stružni nož je kot celota prezahteven za osnovnošolce, vendar če ga razstavimo na posamezne segmente, kot na primer: vodila, sani, koračni motorji, uporabniški vmesnik za struženje … bi ga lahko uporabili kot pedagoški pripomoček na osnovnošolskem nivoju.
