Abstract
In this work, knee prosthesis manufacturing process using CO2 cooling is described. It is necessary to use 5 continuous axis milling in order to manufacture this complex geometry. However, surfaces complexity and material (titanium) low machinability characteristics present a challenge for manufacturers. In this case, process operations and machining parameters for this component manufacturing are specified. Besides, virtual verification of machining process is also performed in order to avoid collisions. Moreover, cooling is a key factor in this case regarding medical components cleaning specifications. Traditional coolants are replaced by CO2 cooling.; Honako lan honetan belaun-protesiko osagarrien fabrikazioa azaltzen da CO2 hozgarri kriogenikoa erabiliz. Osagarrien konplexutasuna dela eta, beharrezkoa da 5-ardatzen interpolazioa gauzatzea fresaketa-eragiketetan. Gainazalen konplexutasun horrek eta materialaren (titanioaren) mekanizagarritasun baxuak mekanizazio-erronka berriak sortzen dituzte. Kasu honetan, osagarrien fabrikaziorako erabilitako mekanizazio-estrategiak eta mekanizazio-aldagaiak deskribatzen dira. Gainera, mekanizazioan ager daitezkeen talkak saihesteko, egiaztatze birtuala erabili da. Horrez gain, hozketa faktore garrantzitsu bat da osagai medikoen garbitasuneko beharrizanei dagokienez. Ohiko hozte-teknikak CO2 hozgarri kriogenikoarekin ordeztu dira.
