Ukunciphisa imo xa kugqiba: izakhi kunye ingqikelelo ahlabayo

Enye yeendlela kunyango ngemiba yezemfundo zesinyithi liyajikeleza na. Kunye wazithwala maholo kunye ukulungele nendawo ophela ngexesha ukwenziwa okanye ukulungiswa ungamalungu. Inkqubo noun kunye umsebenzi osemgangathweni kakuhle kufikelelwa ngokusebenzisa Ukukhetha eyiyo ukunciphisa iimeko.

inkqubo Iimpawu

kaloku akugqiba Ivula yenzelwa koomatshini ezikhethekileyo nge siphume. Iintshukumo eziphambili yokuluka ziqaliswa, nto leyo evumela ukujikeleza into elifakiweyo kuso. Feed movement sizinikele isixhobo ifakelelwe bandixhasa.

Iindidi eziphambili imisebenzi ezithile ziquka mechanical nokuvunda ekujikeni, uyadika, emathambekeni machining kunye vee, lokucheba kunye ukusika, abulawe intambo. Ngamnye kubo kukhatshwa ohambelana iintshukumo lwezixhobo onemveliso: bushing kunye elinjubaqa, ezimilise, basike, amanqaku, ukulisika nakubaxholi intambo. Zahlukene uhlobo iimatshini ingaphatha amancinane kakhulu ezinkulu izinto, ngaphakathi langaphandle imiphezulu, Planar ne-ntathu preform.

izinto ezingundoqo iindlela

nangokukrola mode ekujikeni - iseti Ipharamitha kumatshini isixhobo, ejoliswe ekuphumeleleni ngokugqwesileyo iziphumo. Ezi zibandakanya ezi zinto zilandelayo: nobunzulu, kwelizwi, isantya nesantya yokuluka.

Ubunzulu - a metal ubukhulu mgawuli eshukumayo ukugwebileyo (t, mm). Kuxhomekeke iseti parameters yococeko efanelekileyo abahlukunyezwa. Xa ukubuyela rough t = 0,5-2 mm, agqibileyo - t = 0,1-0,5 mm.

Ukungeniswa - umgama isixhobo isusiwe kwicala longitudinal, osecaleni okanye ethe ngqo malunga omnye revolution ka workpiece (S, mm / uMfu). Kubalulekile iparameters ngokuzimisela yayo iimpawu zeijiyometri esemgangathweni sixhobo ekujikeni.

Isantya othini - inani amathuba ahlangene engundoqo, leyo uthwele workpiece, wenziwe kwisithuba kwexesha (n, v / c).

Isantya - ububanzi sesicatshulwa kwindawo yesibini ifaniswe ubunzulu kwangaphambili nomgangatho enikezelwe kwamaza (V, m / s).

Power inguquko - inani amandla osetyenzisiweyo (P, H).

Ubuninzi, speed kunye namandla - ezibalulekileyo izinto ezalanayo imo ukusika xa Wabaguqukela, ezimisa parameters kunye nokubekwa kwindawo ephezulu kokugqiba into ethile, kwaye nangokuhamba umatshini yonke.

data kokuqala

Ukusuka Ngokwembono iinkqubo inkqubo sakujika ingabonwa njenge inkqubo eluqilima izinto kwinkqubo. Ezi ziquka: lathe isixhobo, i workpiece, wesintu into. Ngenxa yoko, uluhlu izinto ezichaphazela ukusebenza kwale nkqubo. Ngamnye kubo kuthathelwa ingqalelo xa kukho imfuneko ukuze Bala nangokukrola iimeko zaguquka:

• I parametric iimpawu kwezixhobo, alo, amagunya, uhlobo yokusonta ujikelezo kolawulo (stepwise okanye stepless).
• Indlela nokubopha preform (ngokusebenzisa chuck, lo chuck kunye ukuphumla ngcembe, lunettes ezimbini).
• iipropati Physical ukubakhulula ye-metal ngayo. Ngokusekelwe conductivity thermal ayo, ngokuba lukhuni kunye namandla, uhlobo eveliswe yi-chip kunye nohlobo ihambo yayo ngokunxulumene-inventri.
• iimpawu zejometri mechanical zesixhobo: ubungakanani eliyi kumnini, embindini phezulu, ubukhulu, uhlobo kunye eziphathekayo elidlula kunye ehambelana conductivity thermal nesikhundla nobushushu, ubulukhuni, lukhuni, namandla.
• parameters umphezulu ecacisiwe, kuquka lirhabaxa kunye nomgangatho.

Ukuba zonke iinkalo kwenkqubo ingqalelo kwaye esisiso ibalwe, kuba kunokwenzeka ukuba nkulu ukusebenza umsebenzi wayo.

Iinqobo ucikizeko lwezi sakujika

Iinxalenye ukwenziwa ngokwala yokutrima ukujika kaninzi iindlela uxanduva. Kuyahlangatyezwana neemfuno, kuthathelwa ingqalelo inkqubo akhawunti ezintathu ezisisiseko. Eyona nto ibalulekileyo kukuba nkulu intsebenzo ngamnye kubo.

• Ukuthobela izinto mgawuli nibusile into.
• Noun phakathi feed, isantya kunye nobunzulu, nemveliso ubukhulu kunye kugudiswa umgangatho: Minimal ngumngundo ngqo uburhabaxa, ukhululekile iziphene.
• Iindleko Ubuncinane kwezibonelelo.

Inkqubo yokubala iimeko ukusika xa kugqiba lwenziwa ngendlela ophezulu. Kukho iindlela ezininzi ezahlukeneyo.

iindlela zokubala

Njengoko sele kukhankanyiwe, indlela ukusika ngu ekujikeni, kufuneka kuthathelwe ingqalelo inani elikhulu yeemeko ezahlukeneyo kunye parameters. Xa kuphuhliso netheknoloji iingqondo esayensi ziye iinkqubo eziliqela eyenzelwe ukubala iimeko ahlabayo elilelona beengxenye zonke iimeko ezahlukeneyo:

• Mathematics. Iindlela ngqo ekubaleni ekhoyo ngezinto zezibalo.
• Igrafikhi-analytical. Ukudityaniswa ubuchule zemathematika nolweegrafu.
• Table. Ukhetho lwamaxabiso ehambelana neemeko zokusebenza elikhankanyiweyo, iitafile ezintsonkothileyo ezizodwa.
• Machine. Ukusebenzisa le software.

Khetha i ezifaneleke kakhulu ikontraka, ngokuxhomekeke imisebenzi ubunzima inkqubo yokuvelisa.

indlela izibalo

Ngokucophelela kubalwa ukunciphisa iimeko xa sakujika. Iifomula zikhona ezintsonkothileyo ngaphezulu okanye ngaphantsi. Ukhetho sistim emiselwe iimpawu kunye nokuchaneka elifunekayo iziphumo kunye iintsilelo ubuchwepheshe ngokwayo.

Ubunzulu zibalwe umahluko phakathi Ebubanzini workpiece ngaphambi (D) kwaye emva (d) processing. Ngokuba imisebenzi longitudinal: t = (D - d): 2; ngenxa ezinqamlezayo: t = D - d.

feed ichazwe izigaba elikholekileyo:

• manani, nezinika umgangatho umphezulu kuyimfuneko, S _CHER;
• bondle isixhobo ngenxa ngeempawu, S _p;
• ixabiso oluthathela ingqalelo iimpawu ngenxa iinxalenye eqwalasele, S _ubekwa.

Ngamnye onombolo kukuthi ebalwa ngokomgaqo wokubala. Njengoko ifidi ngqo kukhethwa ifunyenwe lincinci i S. Kukho kwakhona generalizes ifomula kuthathelwa ingqalelo geometry we mgawuli, ukuba iimfuno kubunzulu kwangaphambili nomgangatho sakujika.

• _{^{S = (C s * R y}} * r u): (t x * φ z2), mm / uMfu;
• apho C _s - inkcazelo parametric umbandela;
• R ^y - kwangaphambili uburhabaxa, micrometers;
• r ^u - radius njengezona ekujikeni isixhobo, mm;
• t ^x - ubunzulu ukujika, mm;
• φ ^z - ubutsolo angle mgawuli.

-High speed parameters edibanise ujikelezo ziqwalaselwa kubudlelwane ezahlukeneyo. Enye yezinto ebaluleke kakhulu:

_{v = (C v * K v} ): (T m * t x * S y), m / min, apho

• C _v - esimbaxa ngumlingani ukushwankathela eziphathekayo izinto, umsiki, inkqubo meko;
• K _v - inkalo olongezelelweyo eziphawula iimpawu ze;
• T ^m - ubomi isixhobo, min;
• t ^x - ukusika ubunzulu, mm;
• S ^y - ukutya, mm / ISityhi.

Ngokwamanani lula, yaye ukuze izibalo zofikelelo losetyenziso, izinga ukuyijika workpiece icaciswa:

V = (π * D * n): 1000 m / min, apho

• n - speed yokuluka, Rev / min.

Used amandla nezixhobo:

N = (P * V): (60 * 100), Township apho

• apho P - ukusika amandla, H;
• v - speed, m / min.

Le ndlela ingentla ixesha elide kakhulu. Kukho iindidi ngeendidi ifomula zintsonkothe ezahlukeneyo. kakhulu nzima ukukhetha ilungelo ukubala iimeko ahlabayo ngenxa sakujika. Umzekelo eyona ubhetyebhetye kubo inikwe apha.

indlela tabular

Umongo olu khetho kukuba izalathi si zokunikwa izinto ezilawulayo zezi kwiitheyibhile ngokungqinelana idatha yoqobo. Kukho uluhlu abalawuli apho amazinga feed iboniswe njengomsebenzi iimpawu parametric zesixhobo kunye workpiece, isixhobo geometry defined izikhombisi umgangatho komhlaba. Kukho ezinye imilinganiselo inokuthatha imida ubuninzi kuvumelekile ukuba izinto ezahlukeneyo. Ukuqalisa izinto ezifunekayo ukuze ukubala isantya, nayo iitafile ezizodwa.

Le ndlela isetyenziswa ngokwahlukeneyo okanye ngaxeshanye uhlalutyo. Kuyinto elula kwaye ichanekile isicelo elula uthotho kwimveliso izahlulo individual koomasifundisane ekhaya. It ikuvumela ukuba ukusebenza amaxabiso lwedijithali kunye ubuncinane umgudu kunye lokwandlalela.

iindlela graphic-zohlalutyo kunye umatshini

indlela Ujongano i oluncedisayo kwaye isekelwe phezu izibalo. Iziphumo kubalwa abekwa innings apho umgca rascherchivayut kunye isixhobo umatshini kunye izinto ezongezelelweyo ugqibe kwelobubi. Le ndlela - inkqubo entsonkothileyo nzima kakhulu, nto leyo akafanelekanga ukuba imveliso mass.

indlela Machine - ukhetho oluchanekileyo nolufikelelekayo ukuba abanamava lo mfundi Turner, eyenzelwe ukuba ukubala iimeko ahlabayo ngenxa sakujika. Le program inika amaxabiso ichanekileyo ngokungqinelana ne idatha engumthombo ekhankanyiweyo. Baya kufuneka iquke:

• Le okuza eziphawula ebambekayo workpiece.
• Izalathisi elihambisana iimpawu metal isixhobo.
• Geometric Ipharamitha izixhobo sakujika.
• Inkcazelo ngamanani umatshini kwaye kuthetha ukulungisa workpiece kwawo.
• iimpawu parametric yento ngayo.

Ubunzima ezinokuvela sihambisane inkcazelo ngamanani idatha yoqobo. Ngokuchanekileyo zibenze, ungenza ngokukhawuleza ukufumana ukubala ebanzi nangokuchanekileyo imiqathango elidlula ukuba sakujika. Le program kusenokuquka yempazamo, kodwa ibalulekile ngaphantsi kwi ngobuwena manual zezibalo.

ukunciphisa imo xa kugqiba - luphawu uyilo ebalulekileyo egqiba iziphumo zawo. Ngaxeshanye izakhi kunye nezixhobo mazikhethwe Ukupholisa kunye izinto zokuthambisa. Full enengqondo Ukukhethwa complex - sisalathisi onamava iingcali okanye onzima.
