Prototyping thiab ntau lawm qhov chaw sai thiab raug nqi feem ntau yog qhov sib npaug ntawm kev tig nrawm rau CNC machining peev thiab optimized qhov chaw tsim rau cov peev txheej.Yog li ntawm no yog 6 qhov kev xav tseem ceeb thaum tsim qhov chaw rau milling thiab tig cov txheej txheem uas tuaj yeem ua kom lub sijhawm ntau lawm thaum txo cov nqi.
1. Qhov tob thiab txoj kab uas hla
Qhov feem ntau yog interpolated nrog kawg mills, tsis drilled.Txoj kev machining no muaj qhov ua tau zoo ntawm qhov loj me rau cov cuab yeej muab thiab muab qhov zoo dua qhov tiav dua li kev xyaum.Nws kuj tseem tso cai rau peb kom tshuab grooves thiab kab noj hniav nrog tib lub cuab yeej, txo lub sijhawm voj voog thiab ib feem nqi.Qhov tsuas yog downside yog vim qhov txwv ntev ntawm qhov kawg zeb, qhov tob tshaj li rau txoj kab uas hla dhau los ua ib qho kev sib tw thiab yuav tsum tau muab tshuab los ntawm ob sab ntawm ib feem.
2. Qhov loj thiab hom xov
Drilling thiab xov ua sib koom tes.Ntau lub tuam txhab siv "kais" los txiav cov xov sab hauv.Cov kais dej zoo li cov ntsia hlau toothed thiab "screws" rau hauv lub qhov uas tau drilled yav tas los.Peb siv txoj hauv kev niaj hnub no los ua cov xov, ib lub cuab yeej hu ua xov zeb ntxig cov xov profile.Qhov no tsim cov xov meej, thiab cov xov loj (xov ib nti) uas sib koom cov suab tuaj yeem txiav nrog ib qho cuab yeej milling, txuag ntau lawm thiab lub sijhawm teeb tsa.Yog li ntawd, UNC thiab UNF threads ntawm # 2 mus rau 1/2 nti thiab metric threads los ntawm M2 mus rau M12 tuaj yeem siv rau hauv ib lub cuab yeej.
3. Cov ntawv nyeem ntawm ib feem
Koj puas xav kos tus lej, piav qhia lossis lub logo ntawm ib feem?Acceleration txhawb nqa feem ntau ntawm cov ntawv xav tau rau kev ua, muab qhov sib nrug ntawm tus kheej cov cim thiab cov cwj nrag siv los "sau" lawv tsawg kawg yog 0.020 ntiv tes (0.5 hli).Tsis tas li ntawd, cov ntawv yuav tsum concave es tsis tau tsa, thiab 20 taw tes lossis loj font xws li Arial, Verdana lossis zoo sib xws sans serif raug pom zoo.
4. Phab ntsa Qhov siab thiab Feature dav
Tag nrho peb cov riam muaj carbide riam.Cov khoom siv ultra-rigid no muab cov cuab yeej siab tshaj plaws lub neej thiab kev tsim khoom nrog tsawg kawg deflection.Txawm li cas los xij, txawm tias cov cuab yeej muaj zog tshaj plaws tuaj yeem deform, raws li cov hlau tuaj yeem, thiab tshwj xeeb tshaj yog cov yas raug machined.Yog li ntawd, phab ntsa qhov siab thiab qhov loj me yog nyob ntawm qhov geometry ntawm tus kheej thiab cov cuab yeej siv.Piv txwv li, qhov tsawg kawg nkaus feature thickness ntawm 0.020 "(0.5mm) thiab qhov siab tshaj plaws feature qhov tob ntawm 2" (51mm) tau txais kev txhawb nqa rau machining, tab sis qhov ntawd tsis tau txhais hais tias koj tuaj yeem tsim lub dab dej kub finned nrog cov qhov ntev no.
5. Fais fab cuab yeej tshuab dhos
Ntxiv rau peb lub peev xwm milling uas nws kim heev, peb kuj muab cov cuab yeej nyob CNC tig.Cov cuab yeej siv rau ntawm cov tshuab no zoo ib yam li cov ntawm peb lub chaw machining, tshwj tsis yog peb tsis tig cov khoom yas tam sim no.Qhov no txhais tau hais tias eccentric qhov, grooves, flats, thiab lwm yam nta yuav machined parallel los yog perpendicular (axial los yog radial) mus rau "ntev axis" ntawm lub tig workpiece (nws Z-axis), thiab feem ntau ua raws li orthogonal qhov chaw fabricated ntawm machining. center Tib txoj cai tsim.Qhov txawv ntawm no yog cov duab ntawm cov khoom siv raw, tsis yog cov cuab yeej teeb tsa nws tus kheej.Tig qhov chaw xws li shafts thiab pistons pib tawm puag ncig, thaum milled qhov chaw xws li manifolds, gauge thawv thiab valve npog feem ntau tsis siv, siv cov square lossis rectangular blocks xwb.
6. Multi-axis milling
Siv 3-axis machining, lub workpiece yog clamped los ntawm lub hauv qab ntawm raw khoom thaum tag nrho cov nta yog txiav los ntawm mus txog rau 6 orthogonal sab.Qhov loj me yog loj dua 10 "* 7" (254mm * 178mm), tsuas yog sab saum toj thiab hauv qab tuaj yeem ua tshuab, tsis muaj qhov chaw!Txawm li cas los xij, nrog tsib-axis indexed milling, nws tuaj yeem siv tshuab los ntawm ib qho ntawm cov npoo uas tsis yog orthogonal.
