Abstract

U radu je prikazana analiza vremena strojne obrade prirubnica u tvrtki Končar – MK sa svrhom izrade podloga za automatizaciju normiranja vremena proizvodnje koje bi se mogle implementirati u proizvodno-poslovni informacijski sustav tvrtke. Odabran je reprezentativni standardni proizvod iz grupe sličnih dijelova koji se učestalo ponavljaju u proizvodnji, te načinjen CAD/CAM program za 15 varijanti tog proizvoda prema režimima koji se upotrebljavaju u proizvodnji tvrtke. Varijante proizvoda razlikuju se u dimenzijama i značajkama kao što su utor, broj i veličina provrta i sl. Snimana je obrada prirubnica na CNC obradnim centrima i klasičnim tokarskim strojevima te je načinjena usporedba s proračunatim vremenima dobivenim iz simulacije obrade u programu CATIA. Definirani su korektivni faktori koji bi se upotrebljavali prilikom automatiziranog određivanja normi za ove proizvode.

Abstract (english)

The thesis analyses the flange machining time at the company Končar – MK, with the purpose of making a base for the automation of standardisation of manufacturing time that could be implemented in the company’s business process management software. A representative standard product was selected from a group of similar parts frequently recurring in production, and a CAD/CAM program was developed for 15 variations of this product, applying the machining regimes used in the company’s production. Product variants differ in dimensions and features such as groove, holes, etc. The flange manufacturing on CNC machining centres and classical lathe machines was monitored and a comparison was made with the calculated times obtained from the simulation of the manufacturing in the CATIA program. Corrective factors were defined that would be used in automated standardisation of these products.
