Cov lus qhia rau kev txhim kho kev siv hauv chaw sawv tshuam CNC

Txhim kho cov ntaub ntawv sawv tshuam rau kev siv hauv chaw sawv tshuam CNC zoo tshaj plaws

Paub txog kev siv zog, kev sib cuag, thiab kev sawv tshuam hauv kev siv hauv chaw sawv tshuam CNC

Yog xav tau kev pab los ntawm CNC machining, ces yuav tsum tau txhawj xeeb nrog rau ob peb qhov kev xaiv: lub spindle yuav tsum rov meej li cas, tus lej uas chaw pib siv khoom mus rau hauv chaw, thiab lub siab ntawm txhua qhov kho. Ib qho kev surov los ntawm kev tsim kho tshuab pom tias yog tias tsis muaj kev xaiv zoo, ces lub spindle yuav tsis rov meej raws li xws li, thiab yuav tshwm sim cov cuag dab tsi uas yuav ploj tsoom lub khoom uas yuav kho. Tab sis thaum cov feed rate nyob rau hauv qhov chaw zoo tshaj plaws ntawm 0.08 rau 0.2 mm per tooth, lub ru piv yuav smooth dua—txhais tau hais tias zoo dua 34% nyob rau hauv qhov kev tshwm sim. Thiab ceeb to taub tias kev kho siab. Yog tias kho siab dua 40% ntawm lub tool’s diameter, ces yuav ua rau precision thim los, tshwj tsis yog thaum siv khoom nyiag uas zoo li aluminum. Qhov no yog ib qho uas cov neeg kho tshuab nyob rau hauv chaw paug paub zoo heev tom qab kawg tseem pom tseem tsis zoo los ntawm kev xaiv tsis raug.

Thaiv kev sib npaug ntawm tus lej khoom yuav tsum removed thiab lub ru piv zoo

Qhov kev pib txawv ntawm kev ua haujlwm thiab qhov nyob ib puag ncig ntawm chaw nruj xwm yeem tsum tau sau ua ke. Txhawm rau siv dua ob zaus lub sijhawm tshuam tsov, tsis tas li muaj feem ntau tshaj 30%, tab sis tib neeg tseem tuaj yeem tshwm sim rau qhov chaw nqus ntau dua 1.6 µm hauv cov khoom siv hluv. Cov kev tswj hwm kho mob tshaj tsev xws li trochoidal milling tuaj yeem pab tshuam tsov ntau dua 18% thaum twg kuj tseem sau npe Ra < 0.8 µm.

Daim duab piv txwv: Ua kom ciav dej tawm hauv cov khoom siv hluv los ntawm kev sau npe qhov siab

Ib tus neeg tsim khoom tau txais 0.02 mm chaw ntsuas sib npaug hauv cov khoom siv rau cheeb tsam los ntawm kev sau npe qhov siab los ntawm 5 mm mus rau 3 mm. Qhov kev tswj hwm no, thiab muab nrog kev hloov pauv npe roj tso caij, tau tshem tawm 89% ntawm qhov tsis yog los ntawm kev pib txawv tsis tas li muaj feem ntau tshaj sijhawm tshuam tsov. Lub chaw tswj hwm kev xaiv npe ntawm lawv uas muaj AI pab tau tso caij ntau hauv lub sijhawm tshuam tsov.

Kev hloov npe tswj hwm nyob ze sijhawm siv cov cuab yeej tshuaj xyuas thiab kev tswj hwm uas muaj AI pab

Nyob rau hnub no, cov kev kho kom tsim nyog rau qhov kuj thiab qhov tawg ntawm qhov chaw sau nrog siv cov cuab yeej so koob thiab lus txwv kev coj ua thaj pib. Ib qho kws tsim khoom loj tshaj plaws tau txo qhov tsis zoo los ntawm 40% tom qab siv cov neural networks uas pab hloov pauv lub zog tso los ntawm qhov kub ntawm spindle uas raug detection los ntawm cov IoT-enabled monitoring systems.

Cov Ntaub Hlau Avanced thiab Cov Txheej Txheem Kev Tswj Hais Kom Thauv Kev Sib Txawv Nyob Rau CNC Machining Centers

Xaiv cov ntaub hlau sau zoo tshaj plaws nyob rau hauv qhov khoom thiab daim duab

Kev xaiv cov cuab yeej muab ntau txiaj ntsig rau kev ntuag tseeb ntawm qhov loj ntawm CNC machining operations.

Qhov xav tau kom rov pab nplua npluag txhua xyoo tuaj yeem pab cov neeg ua haujlwm tau hloov tshiab raws standards AS9100 uas tau hloov, vim yog qhov tseem ceeb heev thaum tsim khoob siv rau cov khoom uas xav tau kev nthuav dav zoo heev, xws li cov ntawv nplhaib siv hauv cov avtog kub lossis cov khoom siv hauv kev kho mob uas tsum tshwm sim raws leej cai tshaj tshwv.

Sau kev saib xyuas ntxiv mus rau kev saib xyuas kwalitee hauv kuv lub sijhawm

Siv kev saib xyuas ntxiv mus rau kev tshem kuv kev nthuav dav hauv kev tsim khoob

Nyob zoo noj CNC kev pab cuam tshuam tuaj yeem khiav tau qhov tsawg dua 10 microns thaum lawv muab kev sau npe ntawm kev sib txig sib tos thiab kev daws teeb meem rau cov algorithm tshwj xeej. Cov kev xyaum nug pom tias qhov kev tu no nyob rau hauv qhov chaw tuag tseem ceeb tuaj yeem txo qhov tsis paub tu siab los ntawm li 35%, uas yog ib feem ntau zoo dua li just mus nraim qhov kho tshiab. Lub tsev lag luam loj tuaj yeem link nrog cov ntaub ntawv txog lub spindle nyob rau hauv cov kev lag luam enterprise resource planning systems tam sim no. Qhov no pab them rau lawv thay lub tool nyiag lawm dhau ua ntej thaum cov khoom tuaj yeem tsis raug specification los ntawm kev siv ntau.

Siv cov sensor IoT rau kev sau npe nyob rau hauv lub spindle thiab axis nyob rau hauv yam sijhawm

Thaum cov accelerometer tsim nyob ib leeg nrog rau cov sensor kuaj qhov tawm hliav, lawv pab rau lub system feedback kaw kom txo qhov tsis muaj zog ntawm qhov chaw los ntawm 18% mus rau 22% thaum ua ke nrog cov kev caij rau 5-axis. Piv txwv li ib qho CNC machining center tseem nyob rau hauv IoT tam sim no nws tuaj yeem siv dua 2000 qhov chaw hauv ib feeb. Qhov no txhais tau li cas? Txawm yog algorithms AI tuaj yeem pom cov zeeg uas cuam tshuam rau qhov bearing wear phem tshaj li 12 mus rau 15 teev ua ntej yuav puag. Thiab tsi txhob hnov qab rau cov system compensation thermal. Cov system leej little clever no yuav siv tag nrho cov ntaub ntawv sensor thiab tso qhov accuracy ntawm qhov chaw nyob ib haum zoo ib neeg ntawm +/- 3 micrometers hauv txhua qhov sib thooj titanium milling uas nyob ib feem ntau 20 teev uas tej kub yuav cuam tshuam tag nrho.

Kuaj cov ntaub ntawv thawj zaug thiab kuaj tus kheej nyob hauv qhov kev lag luam

Nyob rau hnyav tshaj los ntawm 2023 qhia tau tias thaum cov khaub ncaws los ntawm kev siv kev saib xyuas tsim nyog nrog laser scanners, lawv tau txo cov ntaub cu yeej uas tsis muaj neeg xav tau los ntawm 27%. Cov chaw no ua haujlwm los kom saib xyuas lub dav hlau ntawm qhov chaw rough machining. Yog tias tus nqi hlo li cas tshaj qhov tseem ceeb hauv qhov tolerance range, cov chaw no yuav kho kom meej dua qhov teeb meem ntawm qhov tom ntej. Tom qab cov khoom tau tsim, cov nqi ntawm coordinate measuring machine yog xa mus rau computer-aided manufacturing programs kom cov tool paths tuaj yeem raug kho kom raug. Qhov no tsim ib qho zoo li ib qho kev kho tswj tsis tas cuag mus los ntawm ib qho kho tsev mus rau ib qho kho tsev ntxiv.
