Abstract

U sklopu rada analiziran je trenutni način izvođenja procesa obrezivanja karbonskih proizvoda poduzeća Bugatti Rimac. Na osnovu teorijske podloge tehničke logistike, konkretno logističkih aktivnosti skladištenja i komisioniranja te rukovanja materijalom, i provedene analize utvrđeni su nedostaci procesa skladištenja i manipulacije steznim napravama koje se koriste u procesu obrezivanja za stezanje karbonskih proizvoda prilikom strojne obrade. Posljedica utvrđenih nedostataka je slaba iskoristivost stroja te mali volumen proizvodnje. S ciljem sprečavanja pojavljivanja istih nedostataka na lokaciji nove proizvodne hale te povećanja iskoristivosti stroja i volumena proizvodnje formirani su prijedlozi unaprjeđenja procesa. Razmatrana je mogućnost poboljšanja procesa skladištenja primjenom vertikalnog podiznog modula kao skladišnog sredstva koje udovoljava postavljenim uvjetima. Definirano je transportno sredstvo koje će se koristiti za transport naprava od skladišnog sredstva do obradnog centra te je dan opis interno razvijenog sustava za brzu izmjenu naprava koje dodatno skraćuje proizvodni ciklus. U konačnici prijedlozi poboljšanja integrirani su u proces na temelju kojeg je rađena procjena povećanja iskoristivosti stroja i volumena proizvodnje, kao osnova za određivanje isplativosti ulaganja.

Abstract (english)

This master thesis contains analysis of a current carbon trimming process in Bugatti Rimac company. Based on the engineering logistics theory, more specifically warehousing and material handling theory, and conducted analysis issues in the warehousing and material handling processes of clamping devices were noticed. As a result of the issues lower machine effectiveness occurs which then leads to lower production output. With the goal of improving the existing process and increasing machine's effectiveness and production output suggestions are given. Warehousing of clamping devices using vertical lift module was considered. Multiple means of clamping devices transport are analyzed and one was proposed as a final solution. Furthermore, description of a internally designed solution for easier clamping devices handling with intent to increase machines effectiveness further is given. Finally, proposed solutions are integrated into final warehousing and clamping devices handling process which is then used to determine new values of machines effectiveness and production output. Machines effectiveness and production output can then be used to decide if it is worth to invest into process improvements.
