El projecte AVINT, en el qual ha participat el Centre d\\’Integritat Estructural, Fiabilitat i micromec\u00e0nica els Materials (CIEFMA) de la Universitat Polit\u00e8cnica de Catalunya, ha tingut com a objectiu desenvolupar i implementar una aplicaci\u00f3 per a predir la rugositat i l\\’acabat superficial de peces mecanitzades per a una integritat superficial \u00f2ptima.\r
Addicionalment, el projecte ha perm\u00e8s l\\’obtenci\u00f3 de nous productes i peces amb valor afegit com a eines de mecanitzat, recobriments per a eines i lubrificants\/refrigerants amb major efici\u00e8ncia gr\u00e0cies a les seves propietats funcionals, geom\u00e8triques i mec\u00e0niques.

Augmentar la productivitat reduint peces defectuoses, cost i temps<\/h4>

El mecanitzat constitueix una tecnologia essencial que permet augmentar la competitivitat de les empreses de l\\’\u00e0mbit industrial, ja que es tracta d\\’un sector clau i transversal per la producci\u00f3 de components que s\\’empren en m\u00faltiples aplicacions.\r
Un dels par\u00e0metres m\u00e9s importants utilitzat per a descriure la qualitat de les peces mecanitzades \u00e9s la rugositat, que es fa servir com a descriptor de l\\’acabat superficial, sent un dels aspectes que tamb\u00e9 s\\’utilitzen per a descriure la integritat superficial.\r
Actualment, el percentatge de peces mecanitzades que no compleixen els requeriments de qualitat per rugositat inadequada en s\u00e8ries llargues pot arribar fins a un 8%, depenent de la tipologia de pe\u00e7a i aplicaci\u00f3. Aix\u00f2 suposa elevades despeses en treballs de reparaci\u00f3 i\/o eliminaci\u00f3 de les peces defectuoses com a ferralla, a m\u00e9s de les parades de producci\u00f3 i substituci\u00f3 d\\’eines de mecanitzat per a obtenir peces amb la qualitat desitjada.\r
Per a peces d\\’alt valor afegit i s\u00e8ries m\u00e9s curtes, els temps d\\’operaci\u00f3 solen ser elevats per a evitar la generaci\u00f3 de peces defectuoses, per la qual cosa la productivitat es veu afectada negativament.

El consorci del projecte AVINT ha estat format per deu socis, distribu\u00efts en agents d\\’R+D+I, empreses d\\’activitat en el sector i companyies que aporten servei i tecnologia.\r
El projecte ha concentrat la seva activitat en l\\’optimitzaci\u00f3 de l\\’efici\u00e8ncia de processos de mecanitzat met\u00e0l\u00b7lic, aplicant eines de simulaci\u00f3 i optimitzaci\u00f3 i machine learning per a una major optimitzaci\u00f3 del control de la qualitat i la integritat superficial dels components. Per part seva, CIEFMA UPC ha aplicat el seu coneixement per a la caracteritzaci\u00f3 de les eines de mecanitzat utilitzades.

AVINT ha tingut una durada de tres anys (gener 2018 \u2013 mar\u00e7 2021) i s\\’emmarca en el Programa Operatiu FEDER de Catalunya 2014-2020, l\u00ednia d\\’actuaci\u00f3 de la Comunitat Ind\u00fastries del Futur (IdF) de RIS3CAT, per a l\\’optimitzaci\u00f3 dels processos de mecanitzat.\r
La Comunitat IdF cerca consolidar un pol d\\’innovaci\u00f3 l\u00edder en fabricaci\u00f3 eficient i sostenible a Catalunya que agiliti la cadena de valor de l\\’R+D+I industrial. El projecte, programat en l\\’eix prioritari \\\u00bbPotenciar la recerca, el desenvolupament tecnol\u00f2gic i la innovaci\u00f3\\\u00bb, ha tingut l\\’objectiu espec\u00edfic \\\u00bbTransfer\u00e8ncia i difusi\u00f3 de tecnologia i cooperaci\u00f3 entre empreses i universitats o altres centres de recerca\\\u00bb.\r
El pressupost total d\\’AVINT ha estat de 2.316.720 euros, dels quals 752.523 euros corresponen a l\\’ajuda concedida.
