dc.description.abstractPrimena profilnih strugarskih noževa u industriji prisutna je unazad nekoliko decenija. Upotreba profilnih noževa u industriji je u ekspanziji, a ovu sve veću popularnost mogu pripisati smanjenju troškova proizvodnje i uštede vremena obrade. Sa druge strane, jedan od glavnih nedostataka predstavlja sam metod njihovog projektovanja. Ovaj nedostatak se ogleda kroz ograničenost obrade pravolinijskih i lučnih segmenata izratka. Grudni ugao za svaki segment ima različitu vrednost, što predstavlja dodatno ograničenje. U slučaju da je neophodna primena profilnih noževa za izradu delova složene geometrije, vrednost grudnog ugla zahtevala bi da bude nula. U ovom radu predstavljen je savremen način projektovanja kružnih profilnih noževa primenom CAD sistema. Na ovaj način, ne samo da se obezbeđuje konstantna vrednost grudnog ugla duž celog sečiva koja može biti i različita od nule, već se obezbeđuje i optimalna geometrija alata za obradu željenog materijala. Dodatno je izvršena i eksperimentalna provera geometrije profilnog noža projektovanog uz pomoć nove metode.sr
dc.description.abstractForm tools have been used in industry for a number of decades. Their use is booming and such growing popularity can be attributed to minimized manufacturing costs and shorter manufacturing time. On the other side, one of the major drawbacks is the method of their design. It reflects in the constraints present in the machining of straight-line and circular arc segments of a workpiece. For each segment the rake angle has a different value, which imposes an additional constraint. In case it is necessary to use form tools to manufacture complex-geometry parts, the value of the rake angle would require to be zero. The paper presents contemporary design method of circular form tools by implementing CAD system. This way, it is not only provided a constant value of the rake angle across the entire cutting edge, which can be different from zero too, but also optimum tool geometry for machining a desired material. Additionally, the geometry of a form tool designed using a new method was experimentally tested.en
