Magistrska naloga obravnava določitev metodnega plana za proizvajanje izdelka s tehnologijo hladnega masivnega preoblikovanja in analizo vplivnosti glavnih vhodnih parametrov preoblikovalnega sistema na izbrane izhodne odzive. Izhodna odziva sta bila raztrosa končne višine izdelka in sile v četrti preoblikovalni fazi. Cilj je bilo ugotoviti, ali lahko po zasnovanem metodnem planu proizvajamo izdelek z opremo, ki je na razpolago. Z analizo pa je bila želja ugotoviti, kolikšen raztros obeh izhodnih odzivov lahko pričakujemo in razvrstiti vhodne parametre po vplivnosti na njiju. Metodni plan se je preverjalo z analitičnimi in numeričnimi orodji. Analizo se je izvedlo po Taguchi metodi, prav tako z uporabo numeričnih orodij. Rezultati so pokazali, da je bil zasnovan metodni plan z manjšimi popravki ustrezen. Raztros končne višine izdelka je znotraj tolerančnega območja dimenzije. Prav tako je moč pričakovati majhen raztros preoblikovalne sile. Vhodne parametre je bilo moč razvrstiti samo glede na raztros dimenzije, pri čemer po vplivnosti izstopa masa surovca. Zaradi majhnega raztrosa preoblikovalne sile pa glede na njo ni bilo mogoče razvrstiti vhodnih parametrov z ustrezno statistično značilnostjo.

Abstract

This master's thesis deals with the determination of the forming plan for the production of a product with cold massive forming technology and contains the analysis of the influence of the forming system's main input parameters on selected output responses. The output responses were scatters of the final product's height and the force in the fourth forming stage. The goal was to determine whether or not it is possible to manufacture such products with the available equipment based on the designed forming plan and to find out with the help of the analysis how much scatter of both output responses can be expected and to classify the input parameters by the influence on them. The forming plan was tested with analytical and numerical tools. The analysis was made with Taguchi method and also with the use of numerical tools. The results showed that the designed forming plan was suitable with minor corrections. The scatter of product's final height is within the dimension tolerance zone. Minor scatter of the forming force value is also to be expected. The input parameters could be classified only by the dimension scatter; the slug's mass specially stands out by its influence. It was not possible to classify the input parameters with the adequate statistically significant based on the value of the forming force due to the small scatter of it.
