Optimizacija parametrov frezanja za izboljšanje kakovosti obdelane površine aluminijastih ulitkov : diplomsko delo Visokošolskega strokovnega študijskega programa I. stopnje StrojništvoŠter, SimonV obstoječem proizvodnem procesu se pojavi problem valovitosti na obdelani površini aluminijastih ulitkov, kar predstavlja neskladnost z zasnovo izdelka. Valovitost na obdelani površini je posledica ... vibracij med obdelovalnim postopkom, ki se z obrabo orodja stopnjuje, saj so uporabljena orodja neodporna na vibracije. Namen dela je bil z metodo SPC analizirati obstoječe stanje proizvodnega procesa in nato z uporabo metode DOE določiti najbolj optimalne obdelovalne parametre pri katerih so vibracije najmanjše. Zajem vzorcev za analizo SPC je bil neposreden z obstoječega proizvodnega procesa. Za analizo pa so se uporabili rezultati pridobljeni na podlagi rednega merilnega protokola. S to metodo je bil proces spoznan za stabilnega, kljub temu pa je bila prisotna valovitost na obdelani površini. S pomočjo metode DOE smo, z relativno majhnim številom preizkusov našli najbolj ustrezne parametre za odpravo vibracij. Obravnavni so bili trije parametri, in sicer, število vrtljajev obdelovalnega orodja, hitrost podajanja ter vpenjalni tlak, ki regulira silo vpenjanja obdelovanca na vpenjalno pripravo. Ugotovljeno je bilo, da je tlak najvplivnejši, hitrost podajanja pa nima nikakršnega vpliva na kakovost obdelane površine.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [S.
