20.500.12556/RUL-160304 Vpliv procesnih parametrov brezkoničnega brušenja na kakovost izdelka The Impact of Centerless Grinding Process Parameters on Product Quality Diplomska naloga se osredotoča na kompleksnost okroglega brezkoničnega brušenja. V prizadevanju za ustvarjanje baze podatkov, ki bi olajšala in pospešila sestavljanje ponudb, so bili določeni osnovni parametri, ki najbolj vplivajo na kakovost izdelka. V metodologiji raziskave so opisani različni procesni parametri, kot so odvzem materiala, obodna hitrost in vlečni kot brusilnega koluta, hitrost ter globina poravnavanja ter geometrija brusnega območja. V eksperimentalnem delu so prikazani vplivi navedenih parametrov na kakovost procesa, opisani z meritvami hrapavosti in okroglosti artikla. Hkrati je bil izveden tudi statistični nadzor procesa, metoda, ki jo zahteva vse več podjetij in omogoča vpogled v stabilnost procesa. Ugotovljeno je bilo, da z variacijo nastavitev procesnih parametrov in predvidevanjem njihove medsebojne interakcije lahko dosežemo rezultate, ki so ekonomično sprejemljivi z vidika podjetja, obenem pa zadovoljijo potrebe kupca njihove storitve. Raziskava je pokazala in bila potrjena z metodo SPC, da je proces zadovoljil potrebe po najzahtevnejših omejitvah kakovosti (hrapavost, okroglost) in hkrati dosledno deloval znotraj kontrolnih meja. The focus of the thesis is on the complexity of centerless grinding. In an effort to create a database that would facilitate and expedite the assembly of bids, basic parameters that have the most significant impact on product quality have been determined. The research methodology describes various process parameters, such as material removal, peripheral speed, and pulling angle of the grinding wheel, speed and depth of sharpening, and the geometry of the grinding area. The experimental part illustrates the effects of these parameters on process quality, described by measurements of surface roughness and roundness of the article. Additionally, statistical process control (SPC) was conducted, a method increasingly demanded by companies, providing insights into the stability of the process. It was found that by varying the settings of process parameters and predicting their mutual interaction, results that are economically acceptable from the company's perspective while satisfying the needs of their service customers can be achieved. The research showed, and was confirmed using the SPC method, that the process met the most stringent quality requirements (roughness, roundness) and consistently operated within control limits. brezkonično brušenje procesni parametri brezkoničnega brušenja statistični nadzor procesa hrapavost /kakovost površine okroglost centerless grinding centerless grinding parameters statistical process control roughness/surface quality roundness true false false [P.
