Concurrent engineering based on virtual manufacturing

Abstract

U radu je razmatran koncept konkurentnog inženjeringa koji podrazumijeva simultane aktivnosti u integriranom razvoju proizvoda i procesa, kroz primjenu inovativnih tehnologija virtualnog inženjeringa, posebno u dijelu simulacije proizvodnje, tzv. virtualne proizvodnje. Cilj je da se minimiziraju projektne izmjene u kasnijim fazama projektiranja, a time i vrijeme i troškovi projektiranja proizvoda i pripadajućih procesa. Primjena FE/FV simulacija može eliminirati skupe fizičke prototipove i eksperimente. Vrijeme razvoja se drastično smanjuje, više projektnih alternativa se može provjeriti, što rezultira povećanjem kvalitete. Primjena koncepta ilustrirana je brojnim primjerima numeričkih simulacija proizvodnih procesa korišćenjem SIMUFACT.forming softvera: oblikovanje debljih limova, kovanje, "net-shape" obrada, toplo istiskivanje profila, itd.The paper deals with the concurrent engineering concept that implies simultaneous activities in integrated product and process development, through the application of Virtual Engineering Technologies, especially in the simulation of production, i.e. Virtual Manufacturing. The main goal is to minimize design modifications in final design stages, and therewith time and costs of design of product and related processes. Expensive physical prototypes and experiments can be avoided by applying numerical FE/FV simulations. Development time is drastically decreased; many design alternatives can be verified, leading to quality improvements. Application of CE concept is illustrated through numerous case studies of numerical simulations of processes using SIMUFACT.forming software: thick sheet forming, forging, net-shape forming, hot profile extrusion, etc
