Abstract

Konkurenca v avtomobilski industriji je močna, zato so potrebne nenehne izboljšave podjetij. S tem se lažje prilagaja svetovnemu trgu in zadostuje željam kupcev. Oddelek strojna obdelava v orodjarni se ukvarja z izdelavo orodij za hladno preoblikovanje pločevine. Problem je določiti učinkovitost delovnih strojev in delavcev, glede na to, da gre za specifično delo, kjer se izdelujejo različni izdelki tako po obliki kot tudi po gabaritih. Ne gre za serijsko proizvodnjo izdelave kosov na CNC-obdelovalnih strojih, ampak za individualna naročila upogibnih in rezilnih vložkov za orodja. Potrebno je določiti merila in kriterije, ki omogočajo vpogled v analizo trenutnega stanja in v optimizacijo novega sistema. Obstoječi informacijski sistem podjetja je potrebno nadgraditi do te mere, da se lahko spremlja skupna učinkovitost opreme v podjetju v realnem času. Uporabili bomo koeficient skupne učinkovitosti opreme. Implementiran sistem se izkaže za učinkovitega, saj se na podlagi tega iščejo rešitve in izboljšave. Podaja nam podrobne rezultate, kaj se z delovnim centrom dogaja med procesom obdelave. Vzporedno se je testirala izboljšava enega izmed faktorjev skupne učinkovitosti opreme in se izkazala za uspešno, skrajšali smo obdelovalne čase in izboljšali kakovost izdelave, doseženo na podlagi navodil oziroma strategij obdelave

Secondary title:	Optimization of machining efficiency in a tool shop
Secondary abstract:	Competition in automotive industry is quite strong thus continuous improvements are required within companies. This makes it easier for them to adapt to the global market and meet the customers’ demands. The machine processing department within the tool repair workshop is engaged in manufacturing tools for sheet metal cold forming. A problem that occurs is determining the efficiency of machines and workforce, given that this is a specific type of work where different variations of products are made as well as in various shapes and sizes. This also isn’t a serialized production of CNC machined parts but individual orders of bending and cutting inserts for tools. It is necessary to determine the standards and criteria that provide insight into the analysis of the current situation and optimization of a new system. The company’s existing information system needs to be upgraded to the extent that the overall efficiency of the company’s equipment can be monitored in real time. We will be using the coefficient of overall equipment effectiveness (OEE). The implemented system proves to be effective, as solutions and improvements are based on it. It also gives us detailed results of what happens within the work centre during the machining process. Parallel to it, the improvement of one of the overall equipment effectiveness factors was tested and proved to be successful. The quality of production and processing times were improved, which was achieved on the basis of a set of instructions or the processing strategy.
