Kuyini nesabelo nokuthi ukubala ke?

Ngaphambi uthola kokuqendwa Ngokwengxenye, preform ukwenza okuningi imisebenzi ehlukene. Enye yezindlela ezibaluleke kakhulu ukuzimisela angabonelela ukucubungula. Ubukhulu bayo - umehluko phakathi usayizi workpiece kanye nobukhulu imininingwane umdwebo. Kulesi sihloko, sifunda ukuthi imali ezifana nokuthi ukubala ke.

izinhlobo izibonelelo

Anezingane - ungqimba metal okuyinto esuswa ebusweni workpiece ukuthola kokuqendwa ingxenye. Lokhu kuyadingeka ukuze kuqinisekiswe ukunemba usayizi edingekayo kanye izinga edingekayo we ebusweni workpiece. Siye sathola ukuthi imali enjalo, kodwa manje wazi ukuthi kukhona okuhlukile yayo. Kuye indlela yokukhiqiza isakhi, le izibonelelo kungenzeka Lesisemkhatsini, futhi mezhduoperatsionnymi ezivamile. Njengomthetho, lona wamuva kubalwa ngokungeza mezhduoperatsionnyh. Isibonelelo ingabalwa njengoba usayizi othile, futhi ohlangothini.

Kusukela lapho ukubaluleka kuncike?

kakade Siye sathola ukuthi imali enjalo, kodwa manje sifunda ukuthi izici kungaya ngokuthi lingakanani. Kwasekuqaleni, yebo, imigomo lobuchwepheshe izinga surface futhi ukunemba izingxenye. Ngaphezu kwalokho, ubukhulu nesabelo incike ukucushwa futhi imininingwane lingakanani. Esinye isici esibalulekile ukuthonya lenani elikhethiwe - uhlobo ukukhiqizwa. Akufanele sibakhohlwe mayelana nemininingwane ukufakwa ngesiphambeko kudivayisi.

Ukubala of nesabelo ngezindlela ezimbili

Siye sathola ukuthi onjalo nesibonelelo Iziphi izici ezithinta ubukhulu bawo Manje usuyazi ukuthi ukubala ke. Kukhona izindlela ezimbili: kwezibalo (etafuleni) kanye kohlaziyo (settlement). Umsuka kunqunywa State Amazinga, futhi ngokufanele incike uhlobo workpiece nasekufuyeni umzila. Okokuqala, ukuze ukubala usayizi angabonelela kucutshungulwa indlela kwezibalo, kubalulekile ukuthuthukisa indlela workpiece machining. Ngaphezu kwalokho, imboni yemikhicito tolerances abelwa ukuhwebelana zobuchwepheshe. Manje, ngokuvumelana amatafula, oluxube okuhambisanayo babelwa GOSTs nesabelo R _z kanye h. Ngaphezu kwalokho, kubalulekile ukubala ukubaluleka amaphutha Imininingwane ngekwendzawo. nesabelo kwetheknoloji ibalwa indlela yethebula, kubalulekile ukuba uqale ukubala kusukela ushintsho lokugcina, okungukuthi, oda reverse yenqubo.

Ukuze abale nesabelo indlela kohlaziyo usebenzisa le ndlela elandelayo.

Ukuze evele cylindrical:

Ukuze esipara:

lapho:

• R _z - microroughness value;
• h - the ungqimba isici ukujula;
• ρ _i-1 - ukubaluleka ngeziphambeko Imininingwane ngekwendzawo;
• ε _i - workpiece ukubeka iphutha;
• i - nesabelo kulo msebenzi.

izibonelelo Lesisemkhatsini for machining (okungenani) kubalwa nge ngokunemba high kakhulu - a micrometer, kanye nesidingo ukukhiqiza ukuqoqa phezulu.

Nakuba ezinye uhlobo nesabelo ibalwa, futhi kuyadingeka ukuba acabangele ukuthi inani layo kumele singeqi esiphansi chip ukujiya, okuyinto ethatha ithuluzi ahlabayo ku ebalisisiwe inqubo isinyathelo. Yiqiniso, ezimweni ezihlukahlukene futhi izinhlobo ezahlukene kucutshungulwa amafomula a workpiece vyshenapisannogo ingase ihluke kancane. Ngokwesibonelo, kusukela formula ungqimba isici ukujula ekhishiwe ngesibonelelo yayo (h _i-1) ukugaya emva kokwelashwa ukushisa, kusukela kulokhu ungqimba ebusweni kufanele kugcinwe.
