COMPUTER-AIDED PROCESS PLANNING FOR MACHINING THE ASSEMBLY OF GEAR WITH HELICAL TEETH

Tema diplomskog rada je projektiranje tehnoloških procesa u CAD/CAM sustavu. Na početku je opisana razlika između troosnih i višeosnih obradnih sustava. Prikazane su njihove prednosti kao i nedostaci. U eksperimentalnom dijelu predstavljen je rad sa Siemensovim programskim paketom NX 12 na projektiranju tehnološkog procesa za izradu helikoidnog zupčastog sklopa. Koristeći troosno i višeosno okruženje softvera prikazana je izrada tehnološkog procesa na dva načina. Oba načina su detaljno objašnjena, te je za oba pristupa generirana putanja alata i prikazana simulacija obrade. Pomoću navedenog softvera, uspoređeno je vrijeme potrebno za izradu troosnim i višeosnim obradnim sustavima. Na kraju je opisan postupak izrade tehnološke dokumentacije koja je generirana za oba pristupa izrade zadanog sklopa.The theme of the Master's degree thesis is the design of technological processes in the CAD / CAM software. At the beginning, the difference between the three axis and multi axis processing systems is described. In the experimental part of the Master's degree thesis the work with the Siemens program package NX 12 on the design of the technological process for making the helical gear assembly is presented. Using the three axis and multi axis environment of the software, the creating of a technological process is presented in two ways. Both ways are explained in detail, and for each approach the tool paths are generated and the simulation of process is displayed. With the help of the above mentioned software, the time needed to create process using three axis and multi axis systems was compared, Finally, the process of producing the technological documentation that is generated for both approaches to the production of the given assembly is described
