Abstract
Mikroproizvodnja je ena od najhitreje rastočih vej industrije z vedno večjim trgom novih izdelkov. V tem prispevku je predstavljena alternativna strategija izdelave mikroorodij, ki je bila preizkušena na primeru izdelka s področja mikrofluidnih uporab. Orodje za masovno proizvodnjo izdelkov s postopkom tlačnega brizganja ali vtiskovanja je izdelano s postopkom potopne mikro-elektroerozijske obdelave (MEDM). Posebnost predstavljene strategije je v izdelavi elektrod MEDM z vodnim curkom (VC). Orodje je bilo uporabljeno za vtiskovanje v polimerni material. Globalno gledano, poteka strategija izdelaveod izdelave elektrode za postopek MEDM, s katero bo izdelano orodje zamasovno proizvodnjo, pa do izdelave mikroizdelka. Posebno pozornost smo posvetili lastnostim vsakega od postopkov in izbiri obdelovalnih parametrov ter tako izbiro najboljše kombinacije obdelovalnih postopkov za izdelavo končnega izdelka. Med raziskavo je prišlo do številnih odkritij. To znanje bo pripomoglo razvoju zanesljive in stroskovno najboljše strategije izdelave mikroorodij, kar je podrobneje opisano v prispevku. Poleg tega je podan pregled drugih podobnih raziskovalnih dejavnosti na Univerzi v Ljubljani.

Title:An alternative strategy for microtooling for replication processes
Abstract:
Microproduction is one of the fastest-growing fields in industry, with new demands from the market increasing every day. This work presents an alternative microtooling strategy, which was applied to a microfluidic device case study. This original strategy for a replication process, like hot embossing or injection molding, is based on the combination of the micro-electro-discharge machining (MEDM) process and an electrode machined with water-jet technology (WJ). The final tool was tested with a hot-embossing process by making some test parts in polymers. The process is considered in its global perspective, starting with the fabrication of the tool electrode that will be used to produce the mold involved in the final cast of the microproduct. The addressed issue consists of identifying the capability of each process and then choosing the machining process parameters that will allow the best process combination to obtain the final microproduct.During this investigation several ideas emerge. They should help to identify the most advantageous characteristics of the involved processes inorder to develop a reliable and cost-effective tooling strategy, which are discussed in this contribution. Additionally, an insight is given into similar research activities at the University of Ljubljana.
