Optimization of through-feed centerless grinding parameters

V diplomskem delu so zajete osnove brušenja, postopki brušenja in zgradba strojev. Obravnavana je problematika vodenja proizvodnje brez baze tehnoloških podatkov. Problem predstavlja načrtovanje procesa brušenja, saj je težko predvideti parametre procesa in kakovost obdelanega izdelka. Na ta način je tudi tvegana tudi izdelava ponudb. Da bi se začela ustvarjati baza podatkov, so opisani in določeni parametri prehodnega brezkoničnega brušenja. V eksperimentalnem delu so testirani vplivi različnih parametrov in dejavnikov na hrapavost in okroglost obdelovanca. Izvedeni so testi različnih brusnih kolutov, hitrosti poravnav, globin poravnav, specifičnih odvzemov in geometrije brusnega območja. Spremljan je tudi vpliv različnih dejavnikov na kakovost izdelka. Rezultati so grafično prikazani. Ugotovljen je vpliv obravnavanih parametrov. Obravnavani dejavniki nimajo vpliva. Bistveno je, da je bila izvedena prva tovrstna raziskava, ki daje osnovo za nadaljnje delo in omogoča nekatere poenostavitve za prihodnje raziskave.The diploma thesis covers the basics of grinding, grinding processes and the construction of machines. The issue of managing production without a technological data base is discussed. The problem is the grinding process defining, as it is difficult to predict the process parameters and the quality of the processed product. In this way, the creation of offers is also risky. In order to start creating the database, the parameters of through-feed centerless grinding are described and determined. In the experimental part, the effects of various parameters and factors on the workpiece roughness and roundness are tested. Tests of different grinding wheels, dressing speeds, dressing depths, specific removal rates and grinding area geometry were performed. The influence of various factors on product quality is also monitored. The results are shown graphically. The effects of the discussed parameters is established. The discussed factors have no effect. It is essential that the first research of this kind has been carried out, which provides a basis for further work and enables some simplifications for future research
