Preparing of manufacturing technology of rotational workpieces on example of splined shafts

V podjetju Oprema Ravne d.o.o. smo dobili naročilo za izdelavo serije gredi. Preden pa smo lahko začeli z izdelavo, je bilo treba s pomočjo načrta izdelati tehnologijo proizvodnje in se odločiti, na katerih strojih bomo to gred izdelovali. Zaradi časovnega termina, ki nam je na voljo, sem se odločil, da jo bomo izdelovali na stroju NT 4250 DCG, saj ta omogoča zelo natančno in hitro obdelavo. Ker je ta stroj CNC, je bilo treba izdelati tudi CNC program, ki sem ga naredil v CAM programu ESPRIT 2015. Odločil pa sem se, da naredim tudi stroškovno in časovno primerjavo med obdelavo na klasičnih strojih in obdelavo na NT 4250 DCG.The company Oprema Ravne ltd. got an order for manufacturing a series of axles. But before we could begin with manufacturing we had to with regards to the drawing create manufacturing technology and decide on which machines the axle would be made. Because of time restraint I decided that we would manufacture the axle on the NT 4250 DCG, as it allows fast and precise manufacture. Because this is a CNC machine I also had to make CNC program that I made in CAM software ESPRIT 2015. I also decided to make time and cost comparison of manufacturing of the axle on classical manufacturing machines and NT 4250 DCG
