Kev daws rau cov teeb meem uas tshwm sim hauv cov txheej txheem ntawmworm sib tsoo logsib tsoo iav processing:
Cov hniav zoo yuav tsum yog symmetrical. Kev ua cov hniav yog tus yuam sij rau kev ua cov iav, thiab kev xaiv ntawm nws cov kev daws teeb meem yog nyob ntawm ntau yam, xws li cov cuab yeej siv, qib qhov tseeb, qhov roughness, hardness, thiab lwm yam.
Ua ntej, xyuas kom meej lub installation ntawm lub hob. Lub hob yog ntsia rau ntawm lub mandrel ntawm lub iav hobbing tshuab. Nws yog ib qho tsim nyog yuav tau siv lub micrometer los xyuas seb qhov radial runout ntawm tus thawj coj ntawm ob qhov kawg ntawm lub hob tsis siab tshaj 0.005 mm. Nyob rau tib lub sijhawm, nws yog ib qho tsim nyog yuav tsum tau tsiv mus nyob rau lub sijhawm. Thaum lub hob yog hobbing lub iav, feem ntau tsuas yog cov hniav nruab nrab txiav lub workpiece, yog li cov hniav no yooj yim hnav. Txhawm rau ua kom cov hniav sib npaug thiab ua kom ntev ntev ntawm lub hob, tom qab lub hob txiav ib tug xov tooj ntawm lub zog, nws tuaj yeem txav tau raws li qhov hob axis los ntawm phau ntawv los yog txoj kev siv lub cev muaj zog los ua kom lub neej ntawm lub hob.
Thib ob, tswj qhov zoo ntawm hob sib tsoo. Actively txais yuav hob sib tsoo tshuab, uas muaj cov yam ntxwv ntawm high precision, tsis tshua muaj nqi, yooj yim thiab saj zawg zog khiav lag luam. High-precision linear guides thiab precision indexing daim hlau yog siv los xyuas kom meej qhov tseeb ntawm hob sib tsoo. Kev ywj pheej worm sib tsoo lub log hnav khaub ncaws thiab cov khoom siv kauv thiab cov cuab yeej teeb tsa ntawm lub hob zoo heev txhim kho kev ua haujlwm yooj yim thiab kev ua haujlwm ntawm cov hob sib tsoo.
Thib peb, xyuas qhov kev teeb tsa thiab kev ua haujlwm ntawm kev sib pauv iav. Cov iav pauv yog lub iav hloov tau siv los hloov qhov kev txiav ceev lossis pub tus nqi (saib cov nyiaj txiav) ntawm lub tshuab cuab yeej, thiab tuaj yeem siv rau hauv txoj haujlwm sib hloov hauv daim ntawv thov.
Los ntawm kev siv cov khoom sib pauv, tus thawj nce (down) ceev kis tau tus mob tuaj yeem hloov mus rau hauv qis (nce) kev sib kis ceev, thiab kev sib kis sib kis tau zoo dua. Yog li ntawd, txhawm rau txhawm rau ua kom lub tshuab ua haujlwm ib txwm muaj, kev teeb tsa thiab kev ua haujlwm ntawm kev sib pauv hloov pauv yuav tsum tau kuaj xyuas lub sijhawm. Iav sib tsoo tshuab yog cov cuab yeej ua haujlwm tseem ceeb rau cov cuab yeej ua haujlwm siab thiab siab ceev hnyav-load iav. Nyob rau hauv kaum xyoo dhau los, lub rear qag spiral bevel iav khub ntawm lub tsheb (tshwj xeeb tshaj yog lub arc shrinking iav kis tau tus mob ntawm Gleason system) kuj yuav tsum tau ib tug loj npaum li cas ntawm cov khoom tsim. Tom qab lub arc shrinking iav kauv bevel iav yog kho cua sov, cov txheej txheem tiav yuav tsum muaj lub iav sib tsoo (lossis sib tsoo) tshuab.
Tam sim no, qhov kev txiav txim siab zoo ntawm worm sib tsoo log iav yog txoj kev loj hlob ntawm iav shaping tshuab. Piv nrog rau cov txheej txheem shaping ib txwm, nws muaj qhov zoo ntawm kev sib kis tsis zoo, sib tshooj loj, thiab kev co me me. Kev ua tiav ntawm kev txiav txim siab shaping zog feem ntau yog siv txoj kev sib tsoo, suav nrog txoj kev tsim thiab txoj kev loj hlob. Txoj kev sib tsoo tshuab yog tsuas yog siv rau kev ua tiav ntawm lub zog loj modulus, tshwj xeeb tshaj yog rau kev sib tsoo thiab shaping ntawm hnyav-loaded thiab loj modulus zog.
