Abstract

Razvoj suvremene proizvodnje i konstruiranje sve složenijih proizvoda definira smjer razvoja obradnih sustava. Primjenom suvremenih materijala znatno boljih mehaničkih i fizikalnih svojstava, nameće se pitanje efikasnosti konvencionalnih postupaka obrade. Uz kontinuirano unaprjeđenje suvremenih materijala i proizvoda, razvijaju se brojni nekonvencionalni i hibridni procesi obrade.
U ovom diplomskom radu opisani su svi značajniji nekonvencionalni postupci obrade odvajanjem. Podijeljeni su na nekoliko skupina, ovisno o vrsti energije koju koriste tijekom procesa obrade. Detaljno su opisani principi rada, njihova primjena te prednosti i nedostatci svakog procesa obrade. Poseban je naglasak stavljen na elektroerozijsku obradu, kao jedan od najbitnijih postupaka obrade u alatničarskoj industriji. Nadalje, detaljno je opisan postupak projektiranja grafitne elektrode za elektroeroziju. Opisan je postupak odabira materijala, analize površina, modeliranje površina i kreiranja EDM elektrode pomoću Tebis-ovog softverskog modula za izradu elektroda, izrada dokumentacije i NC programa za obradu te završna kontrola i mjerenje na CMM uređaju.

Abstract (english)

The development of modern production and the construction of increasingly complex products defines the direction of development of machining systems. By applying modern materials with significantly better mechanical and physical properties, the question of the efficiency of conventional processing procedures arises. With the continuous improvement of modern materials and products, numerous unconventional and hybrid machining processes are being developed.
This thesis describes all significant unconventional separation processes. They are divided into several groups, depending on the type of energy they use during the processing. The principles of operation, their application and the advantages and disadvantages of each processing are described in detail. Special emphasis is placed on EDM, as one of the most important machining processes in the tool industry. Furthermore, the process of designing a graphite electrode for electroerosion is described in detail. The procedure of material selection, surface analysis, surface modeling and EDM electrode creation using Tebis software module for electrode fabrication, documentation preparation and NC processing program, and final control and measurement on the CMM device is described.
