Isivinini sokusika ngokugaya, ukujika nezinye izinhlobo zokufakelwa kwezinxenye

Ukubalwa kwezinqubo zokusika kuyisigaba esibaluleke kakhulu ekukhiqizeni kwanoma iyiphi ingxenye. Kubaluleke kakhulu ukuthi kube nemicabango. Lokhu kungenxa yokuthi imisebenzi ehlukene yokusebenza imishini kuyadingeka ukuba ukhethe ngokuzenzakalelayo isivinini sokusika, umvuthwandaba wokujikeleza we-spindle, inani lesondlo, nobukhulu besendlalelo okufanele ususwe. Imodi ye-Rational - lokhu kunjalo, lapho izindleko zokukhiqiza zizobe zincane, futhi ikhwalithi yomkhiqizo - inembile kakhulu.

Izimiso eziyisisekelo zokubala

Ukuze ukhiqize ingxenye ngenani elidingekayo kanye neklasi lokunemba, okokuqala yenza umdwebo wayo bese upende ubuchwepheshe bomzila. Ngaphezu kwalokho, kubaluleke kakhulu ukukhetha umsebenzi osebenza kahle (ukufaka, ukusika, ukugoqa) kanye nezinto ezidingekayo okuvela kulo mkhiqizo. Ukukhetha ithuluzi lokusika nalo msebenzi obaluleke kakhulu. Ngomsebenzi ngamunye ngamunye, ithuluzi elidingekayo (umseshi, umshini wokugaya, u-drill bit, i-countersink) ukhethiwe.

Ngaphezu kwalokho, into ngayinye ebhaliswe ku-teknoloji yokuhambisa, inqubo ehlukile yenziwa, noma ngabe ifakwe endaweni efanayo yomsebenzi. Isibonelo, udinga ukwenza imbobo D = 80 mm bese usika intambo yangaphakathi yamatrikhi ngokunyuka kweP = 2 mm. Ngomsebenzi ngamunye, kuyadingeka ukhethe ngokuhlukile ukwaziswa okunjengokusika ukujula, isivinini sokusika, isivinini, nokukhetha ithuluzi lokusika.

Ikhwalithi yesimo esidingekayo

Kubalulekile ukucabangela futhi uhlobo lokucubungula (ukuqedela, ukukhwabanisa nokuqeda ukuphela), ngoba ukukhetha kwama-coefficients ekubaleni kuncike kulezi zimingcele. Njengomthetho, ngesikhathi sokuvuthwa, isivinini sokusika sinkulu kakhulu kunokuqedela. Lokhu kuchazwa ngale ndlela: ngcono ikhwalithi yokuphathwa kwendawo, okungenani kufanele kube yijubane layo. Kuyathakazelisa ukuthi uma uvula i-titanium alloys, inani le-roughness landa ngamandla, ngoba ukunyakaza okuqinile kuvela endaweni yokuphathwa, kodwa akuthinti imingcele uRa noRz nhlobo.

Izinto ezithinta isivinini sokusika ngesikhathi sokugaya nezinye izinto

Inqwaba yezici zithonya ukukhethwa kwezibalo. Zonke zihluke phakathi kwazo kuye ngokuthi uhlobo lokusebenza ngomsebenzi. Isibonelo, ukuze uthole izimbobo zokugaya, ungakhetha ukudla okuphindwe kabili njengokukhamba. Ngaphezu kwalokho, leli pharamitha, lapho lisetshenzwa ngaphandle kwezinto ezikhawulayo, likhethwa ukuba livumeleke kakhulu, ngokusho kwamandla amathuluzi asetshenzisiwe. _. Uma uphahla futhi usika emanzini, i-coefficient yengezwa kwifomula eyisisekelo yohlelo lokusika, olucabangela umthwalo wethonya - K _{v .}

Uma ukushaya, kubalulekile ukulalela ukukhethwa kwethuluzi lokusika, ngoba ukusebenzisa umcibisholo ekumeni kudinga ukuhoxiswa kwebhuku, ngakho-ke ijubane kufanele libe lincane.

Ijubane lokusika lokugaya lixhomeke ebukhulu besithuluzi (D) nobubanzi bendawo (B). Ngaphezu kwalokho, lapho kusetshenzwa izinsimbi zensimbi ngezinsimbi zokugcina, kudingekile ukuba ubeke umsebenzi owenziwe ngomsebenzi ngokuhambisana nethuluzi lokusika. Uma ungayinaki le mithetho, ukumelana kwayo kunganciphisa kakhulu.

Lesi isibonakaliso esibaluleke kakhulu esithinta ukubala kwejubane lokusika. Kubonisa isikhathi sokusebenza kwethuluzi lokusika ngaphambi kokuba lishaye. Inkathi yokuqina ikhuphuka ngokucubungulwa kwamathuluzi amaningi.

Amafomu Eyisisekelo

Isivinini sokusika kunoma yikuphi ukusebenza ngokuyinhloko kuncike kuthebhu ekhethiwe yokukhethwa, impahla yomsebenzi, ukujula nenani lokudla. I-formula yayo ithonywe indlela yokusebenzisa . Isivinini sokusika singanqunywa noma indlela ye-tabular noma ngokubala. Ngakho-ke, ngenxa yokubopha, kanye nokuphenduka kwangaphandle, okuguquguqukayo nokuhamba kwesikhathi eside, ifomula elandelayo isetshenziswa.

Lokhu kubalwa kuhluke kanjani kokunye? Uma ukusika, ukusika nokusika, ukujula kokusika akucatshangelwa. Kodwa kwezinye izimo, inani elinjalo njengobubanzi be-slot lingathathwa futhi. Isibonelo, lapho i-shaft iphathwa ngokubanzi, ububanzi bayo buzocatshangwa, futhi uma i-groove iphendukile, ukujula kwayo kuzocatshangelwa. Ngenxa yokuthi kunzima ukusika umsika wokusika, i-feedrate ayikhethwanga ngaphezu kuka-0.2 mm / rev, futhi isivinini sokusika singama-10-30 mm / min. Ungakwazi futhi ukubala ngesinye ifomula.

Uma ukugaya, ukuthutha, ukuthutha futhi ukuyibeka kubalulekile ukucacisa isivinini sokusika kanye nesilinganiso sokudla ngendlela efanele. Uma izindinganiso zikhulu kakhulu, ithuluzi lokusika lingase 'lishise' noma liphule. Ukubala ngesikhathi sokumba, ifomula elinikezwe ngezansi lisetshenzisiwe.

Isivinini sokusika sokugaya sincike ekugqineni kwesinqunyi, inani lamazinyo nobubanzi bomshini owenziwe ngaphakathi. Ukujula okumele kukhethwe kunqunywe ukuqina namandla omshini, kanye nezibonelelo ezihlangothini. Inani lokumelana nomgogodla lithinta ububanzi balo. Ngakho-ke, uma i-D = 40-50 mm, bese kuba ngu-T = 120 imizuzu. Futhi uma i-D isendaweni yobubanzi buka-55-125 mm, inani le-T liyi-180 imizuzu. Isivinini sokusika sokugaya sinefomula eboniswe esithombeni.

Inothi:

C _v - coefficient, okuyinto kuxhomeke izakhi mechanical of surface ukuphathwa.

Ukumelana no-T we-thuluzi lokusika.

S iyinani lemali yokudla.

T ukujula kokusika.

B - ububanzi bokukhokha

I-Z - inani lamazinyo we-cutter.

D ububanzi bomgodi osetshenzisiwe (kwezinye izimo, ithuluzi lokusika, isibonelo, i-drill)

M, x, y yizinto ezivezwayo (ezikhethiwe kusuka ematafuleni), ezithathwa ngezimo ezithile zokusika futhi, njengomthetho, zinamanani m = 0.2; X = 0.1; Y = 0.4.

K _v yisici sokulungisa. Kuyadingeka, ngoba izibalo zenziwa ngokusebenzisa ama-coefficients athathwa ematafuleni. Ukusetshenziswa kwalo kwenza kube lula ukuthola inani langempela lejubane lokusika ngokubheka amanani athile wezinto ezibalulwe ngenhla.

Indlela yethebula nehlelo

Njengoba izibalo ziyinkimbinkimbi, kunezintafula ezikhethekile ezincwadini ezikhethekile nasezinhlobonhlobo ezahlukene ze-inthanethi, lapho imingcele edingekayo ibonisiwe kakade. Ngaphezu kwalokho, kunezinhlelo ezizenza ngokwayo ukusika izindlela. Kule njongo, uhlobo oludingekayo lokumisa lukhethiwe kanye nemingcele efana nokusebenza kwesikhumba kanye nokusika izinto ezidingekayo, ubukhulu obudingekayo, ukujula, ukuchithwa kokulinganisa kufakiwe. Lolu hlelo ngokwalo lubala isivinini sokusika sokuphendulela, ukuphakela kanye nesivinini.
