Abstract

V diplomski nalogi je predstavljena primerjava med uporabo trohoidnega CNC frezanja in klasičnega CNC frezanja. Cilj primerjave je doseči čim krajše obdelovalne čase. Primerjava je izvedena na obdelovancu iz nerjavečega jekla 1.4404. V nalogi so predstavljene teoretične osnove obdelave, predstavitev obdelovalnega stroja, opis frezal ter material obdelovanca. Naloga temelji na eksperimentu, ki je ključen del naše raziskave. V tem eksperimentu smo na izdelku iz redne proizvodnje primerjali klasično in trohoidno vrsto obdelave, tako da smo izdelek izdelali na oba načina. Pri tem smo natančno spremljali čase obdelave ter obrabo orodja. Na koncu smo primerjali dejanske čase obdelave obeh načinov frezanja na izdelku ter naredili stroškovno analizo. Dokazali smo, da je v našem primeru trohoidno frezanje hitrejše in cenejše od klasičnega ter da je bila obraba frezala vidno manjša pri uporabi trohoidnega frezanja.

Secondary title: Optimizing machining times with trochoidal milling
Secondary abstract: The thesis presents a comparison between the use of trochoid CNC milling and conventional CNC milling. In the thesis we aim to achieve shortest possible machining times. The comparison is made on a workpiece made of stainless steel 1.4404. The thesis presents the theoretical foundations of machining, equipment used in the experiment, presentation of cutting tools and description of workpiece material. The thesis is based on an experiment, that was the main part of our research. In the experiment, we compared both machining methods by manufacturing a product from our production using both approaches. During the process, we carefully monitored machining times and tool wear. In the end of the experiment, we compared actual machining times of both methods and conducted cost analysis. We demonstrated that, in our case, trochoidal milling was faster and more cost-effective than the conventional method, and that the tool wear was visibly lower when we used trochoidal milling.
