Analiza možnosti nadgradnje obstoječega klasičnega frezanja s tehnologije trohoidne obdelave

Grbec, Tadej (author), Pušavec, Franci (mentor)

V orodjarstvu se stalno razvijajo nove tehnologije za povečanje produktivnosti in zmanjšanje stroškov obdelave. Ena od teh je tehnologija trohoidnega frezanja, pri kateri visoke podajalne hitrosti in uporaba celotne spirale orodja ugodno vplivajo na hitrost obdelave in obrabo orodja. V tem delu smo na realnem izdelku naredili primerjavo obdelave na klasičen način ter s trohoidno tehnologijo. Pri obeh tipih obdelave smo analizirali čase obdelave, obrabo orodja ter sile med obdelavo in jih nato primerjali med sabo. Ugotovili smo, da so sile med obdelavo pri trohoidni obdelavi veliko manjše kot pri klasični obdelavi. Prav tako je obraba orodja veliko manjša. Izkazalo se je, da je tudi čas obdelave krajši pri trohoidni obdelavi, vendar pa je tu, razlika manjša od pričakovane.

• Title: Analysis of the possibility of upgrading the existing conventional milling with the trochoidal technology

Abstract

In the tool technology processes new technologies are constantly being developed to increase productivity and reduce processing costs. One of these is the trochoidal milling technology where high speed feeds and the use of the entire tool spiral have a beneficial effect on machining speed and tool wear. In this work we made a comparison between conventional milling and trochoidal milling on a real life product. For both machining types we analysed the processing times, the tool wear and the processing forces. The results were then compared with each other. We found that the forces during the trochoidal milling are much lower than in conventional machining. Also the tool wear was much lower. It also turned out that the processing time of the trochoidal milling was shorter but the difference here was less than expected.
