Dinamika I Tochnost' Tortsovogo Frezerovaniya

Sovershenstvovanie tyazhelogo, transportnogo i energeticheskogo mashinostroeniya svyazano s uvelicheniem kolichestva tochnykh krupnogabaritnykh detaley, tekhnologicheskie protsessy izgotovleniya kotorykh vklyuchayut tselyy ryad frezernykh i rastochnykh operatsiy. Effektivnost' obrabotki rezaniem krupnogabaritnykh detaley sushchestvenno zavisit ot dinamicheskogo povedeniya tekhnologicheskoy sistemy "stanok-prisposoblenie-instrument-detal'". Eta zavisimost' podtverzhdaetsya mnogochislennymi issledovaniyami i prakticheskim opytom tekhnologov predpriyatiy. Odnako otsutstvie kolichestvennykh zavisimostey mezhdu dinamicheskimi kharakteristikami tekhnologicheskoy sistemy i razlichnymi faktorami protsessa rezaniya ne pozvolyaet naznachat' naibolee effektivnye rezhimy rezaniya dlya konkretnykh tekhnologicheskikh protsessov. Dlya resheniya problem povysheniya effektivnosti rezaniya i snizhenie vibratsiy pri tortsovom frezerovanii, aktual'nymi stanovyatsya zadachi po razrabotke dinamicheskoy modeli avtokolebaniy tekhnologicheskoy sistemy s tsel'yu analiza usloviy ikh vozbuzhdeniya i intensivnosti, otsenki ikh vliyaniya na kachestvo obrabotannoy poverkhnosti, razrabotka sposobov i sistem tekhnicheskogo diagnostirovaniya sostoyaniya sistemy.
