The 3D model was first made in ArtCAM, from where the STL file was later uploaded to SolidWorks. The parameters for the HSR (high speed roughing), and HSM (high speed machining) operations were determined in SolidCAM. The findings show that a combination of operations from HSR and HSM group are the best choice, considering the shape of the model and the capabilities of the machine, as the best ratio between the quality of the surface and the time needed for the operation is provided by these. Operations differ with regard to the tool path and parameters that can be adjusted. The operations were compared and the best results are achieved when the HSR operations "Contour Roughing" and then "Rest Roughing" are used and when the HSM operation "3D Constant Step Over" is used, where the machining time amounted 4 hours and 1 minute. Finally the G code was made for our productV delu smo izvedli analizo optimizacije procesa obdelave umetniškega lesenega izdelka (okvir ogledala) na 3-osnem CNC stroju. Iz grafične slike smo najprej v programu ArtCAM izdelali 3D model, triangulirali njegovo površino in ustvarili STL datoteko. To smo naložili v program SolidWorks, kjer smo z njegovim dodatkom SolidCAM določili parametre obdelave. Grobo obdelavo smo določili z operacijami HSR (high speed roughing), fino pa s HSM (high speed machining). Posamezne operacije smo primerjali in ugotovili, da bi najkrajši čas obdelave pri najboljši kvaliteti dobili pri izbiri HSR operacij "Contour Roughing" nato "Rest Roughing" ter HSM operacije "3D Constant Step Over", znašal pa bi 4 ure in 1 minuto. Izdelano kodo smo preverili s simulacijo izdelave ter na koncu izdelali G kodo za naš izdelekTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza lesarjev Slovenije
