Ib qho kev siv ntau hauv kev tsim machining ntawm cov khoom siv tshuab yog qhov kev sib piv, uas yooj yim, ceev thiab tsim nyog. Daim ntawv thov yuav tsum muaj cov ntaub ntawv tsim nyog thiab ntau yam ntawm cov ntaub ntawv thiab cov ntaub ntawv pov thawj tau muab rau hauv ntau yam kev qhia txog kev tsim kho tshuab tam sim no. Feem ntau, nto roughness yog sib xws nrog dimensional kam rau ua theem. Feem ntau hais lus, qhov me dua tus qauv tolerances teev rau machining thiab zus tau tej cov mechanical qhov chaw, qhov me me ntawm qhov chaw roughness tus nqi ntawm cov neeg kho tshuab qhov chaw, tab sis tsis muaj kev ruaj ntseg kev sib raug zoo ntawm lawv.
Mechanical qhov chaw machining lub zog yog lub peev xwm ntawm qhov tsis ua kom tawg los yog ua rau ntau tshaj qhov tso cai ntawm cov yas deformation thaum ua haujlwm, thiab yog qhov yooj yim tshaj plaws rau txhua qhov kev ua haujlwm ib txwm muaj thiab kev nyab xeeb ntawm cov khoom siv. Standard countermeasures los txhim kho lub zog ntawm qhov chaw yog: nyob rau hauv thiaj li yuav nthuav tau cov specifications ntawm qhov kev pheej hmoo ntawm cross-section, nthuav lub sij hawm ntawm inertia ntawm tus ntoo khaub lig-section, zoo tsim lub cross-section ntawm rooj plaub; kev xaiv ntawm cov ntaub ntawv muaj zog, cov ntaub ntawv raw los nthuav cov txheej txheem kev kho cua sov los txhim kho lub zog thiab txo cov thermal kev nyuaj siab, kev lag luam tsim cov txheej txheem los txo lossis tshem tawm cov teeb meem tsis zoo, thiab lwm yam; txhawm rau txo cov load ntawm qhov chaw kom txo tau qhov kev ntxhov siab, thiab lwm yam, yuav tsum tau muab kev koom tes zoo hauv cov qauv ntawm cov khoom.
1, positioning yuam kev: positioning yuam kev feem ntau muaj xws li lub benchmark tsis overlap yuam kev thiab positioning vice manufacturing inaccuracy yuam kev.
2, kev ntsuas qhov yuam kev: cov khoom hauv kev ua haujlwm lossis kev ntsuas tom qab ua tiav, vim yog txoj kev ntsuas, ntsuas qhov tseeb, nrog rau cov khoom ua haujlwm thiab cov ntsiab lus thiab lub hom phiaj cuam tshuam ncaj qha los ntawm kev ntsuas qhov tseeb.
3, cov cuab yeej yuam kev: txhua yam cuab yeej hauv cov txheej txheem txiav yog qhov tsim nyog los tsim kev hnav thiab tsim kua muag, thiab yog li ua rau qhov loj thiab cov duab ntawm lub workpiece hloov.
4, fixture yuam kev: lub luag hauj lwm ntawm lub fixture yog ua kom lub workpiece sib npaug zos rau cov cuab yeej thiab lub tshuab cuab yeej muaj qhov tseeb txoj hauj lwm, yog li lub geometric yuam kev ntawm fixture ntawm lub machining yuam kev (tshwj xeeb tshaj yog txoj hauj lwm yuam kev) muaj kev cuam tshuam zoo.
5, lub tshuab cuab yeej yuam kev: suav nrog spindle rotation yuam kev, kev qhia yuam kev thiab tsav saw yuam kev. Spindle rotation yuam kev yog hais txog qhov tseeb axis ntawm kev sib hloov ntawm spindle lub sij hawm txheeb ze rau nws qhov nruab nrab axis ntawm kev sib hloov ntawm tus nqi ntawm kev hloov, nws yuav ncaj qha cuam tshuam rau qhov tseeb ntawm lub workpiece raug machined.
