Tom qab ntau tshaj 20 xyoo ntawm kev paub thiab kev kawm nyob rau hauv kev lag luam molding, kuv tau sau thiab hais txog "Yim Yam Tseem Ceeb" rau kev txhaj tshuaj molding: "Tus txiv neej, tshuab, khoom siv, txoj kev (txheej txheem), Ib puag ncig, pwm, ntsuas (Kev soj ntsuam), thiab tsim (Tsev tsim khoom). Qhov no zoo ib yam li tsib lub ntsiab lus tau hais los ntawm Mr. Suhas Kulkarni, tshwj tsis yog tias Suhas tau saib peb lub ntsiab lus ntawm tib neeg, ib puag ncig, thiab kev ntsuas.
Txawm li cas los xij, nws tseem ceeb heev uas Suhas suav nrog "cov qauv tsim" ua ib qho tseem ceeb, thiab muab tso ua ntej.
Cov yim yam no txiav txim siab qhov ua tiav lossis tsis ua tiav ntawm cov khoom tshiab thiab kev tsim pwm tshiab, txiav txim siab tus nqi ntawm kev txhaj tshuaj molding ntau lawm, thiab thaum kawg txiav txim siab tus thawj coj cov txiaj ntsig. Lawv yog cov xov tseem ceeb thiab cov txheej txheem tseem ceeb hauv kev lag luam molding. Lub yim yam ntxiv thiab sib cuam tshuam nrog ib leeg; lawv tsis tuaj yeem suav hais tias nyob hauv kev sib cais.
Ntawm yim yam tseem ceeb, cov pwm yog qhov tseem ceeb tshaj plaws; 70% ntawm kev txhaj tshuaj molding tsis raug yog tshwm sim los ntawm cov teeb meem pwm.
Tsis pub dhau pwm pwm, lub rooj vag yog qhov tseem ceeb tshaj plaws; 70% ntawm cov teeb meem pwm muaj feem xyuam nrog lub rooj vag. Qhov no, ntawm chav kawm, tsis txhais hais tias lwm yam tsis tseem ceeb; nws tsuas yog ib qho kev faib ua feem ntau tau los ntawm kev siv tswv yim dav dav.
Ua raws li cov txheej txheem ntawm kev tsim khoom, cia peb pib nrog cov khoom tsim. Hais txog cov khoom tsim, ib lo lus uas yuav tsum tau hais yog DFM: Tsim rau Kev Tsim Khoom / Tsim rau Kev Tsim Khoom.
Kev tsim qauv zoo yuav tsum xav txog cov yam ntxwv xws li kev yooj yim ntawm kev tsim khoom, tus nqi tsim khoom tsawg, kev ua haujlwm siab, thiab tus nqi qis. Cov khoom tsim yog qhov chaw. Tsis yog txhua tus tsim qauv tsim muaj kev paub zoo hauv pwm thiab txhaj tshuaj molding. Cov neeg uas raug cais tawm ntawm qhov chaw tsim khoom thiab ua haujlwm tom qab kaw qhov rooj yuav tsim cov khoom uas tsis tsim nyog rau pwm thiab txhaj tshuaj molding ntau lawm. Thaum peb pom cov xwm txheej zoo li no, peb yuav tsum muab cov lus teb raws sijhawm rau tus neeg siv khoom. Nrog rau tus cwj pwm ntawm kev xav txog tus neeg siv khoom zoo tshaj plaws, peb yuav tsum yaum tus neeg siv khoom kom ua tiav qhov yeej - yeej qhov xwm txheej.
Ib yam li ntawd, cov tsim pwm kuj tseem yuav tsis nkag siab txog kev txhaj tshuaj molding, uas ua rau muaj teeb meem ntau hauv cov pwm tsim, uas thaum kawg tsis tuaj yeem ua tiav ntau lawm. Qhov no coj teeb meem tsis kawg rau kev txhaj tshuaj molding tom ntej. Yog li ntawd, txhaj tshuaj molding engineers yuav tsum koom nrog hauv kev ntsuam xyuas pwm tsim thaum lub sij hawm tsim pwm pwm. Cov teeb meem muaj peev xwm los ntawm kev tsim pwm uas tuaj yeem teeb meem kev txhaj tshuaj molding tom ntej yuav tsum tau tshuaj xyuas thiab sib tham ua ntej nrog tus tsim pwm.
Siv zog los daws cov teeb meem tsim pwm thaum lub sij hawm tsim qauv, tshem tawm cov teeb meem ntawm lub sprout theem. Cov tswv tiag tiag siv cov kev ntsuas ua ntej cov teeb meem ncav cuag kev txhaj tshuaj molding ntau lawm kom tsis txhob lawv tag nrho. Es tsis txhob tos kom txog thaum cov pwm hloov mus rau kev tsim khoom rau li ntawd -hu ua "kev txhim kho thaum tsim khoom," uas tsis tsuas yog ua rau cov pwm qis qis thiab cov nqi tsim khoom siab tab sis kuj tseem tuaj yeem ua rau xa tsis raws sijhawm. Qhov no cuam tshuam rau tus thawj coj cov txiaj ntsig thiab tseem tuaj yeem ua rau poob cov neeg tseem ceeb vim kev xa khoom qeeb, ua rau lub tuam txhab lub koob npe nrov.
Tib txoj cai siv rau cov teeb meem pwm:
Ua ntej, cov pwm tsim theem yog lub sijhawm zoo tshaj plaws los tiv thaiv cov teeb meem nyuaj thiab nyuaj tom qab txhaj tshuaj molding ntau lawm . 70% ntawm cov khoom teeb meem yog tshwm sim los ntawm kev tsim pwm tsis tsim nyog. Optimizing pwm tsim los tiv thaiv cov khoom teeb meem yav tom ntej yog "kev kho mob ua ntej nws tshwm sim." Lub sijhawm no, kev mob tshwm sim hauv daim tawv nqaij, tus nqi kho mob qis tshaj plaws (tsuas yog hloov kho cov duab kos rau hauv lub computer), thiab kev puas tsuaj rau tus neeg mob yog tsawg.
Qhov thib ob, qhov kev sim thiab kev kuaj sim yog qhov thib ob - qhov rai zoo tshaj plaws los kho cov teeb meem nyuaj. Lub sijhawm no, cov pwm twb tau ua lawm. Kev hloov kho pwm yog qhov nyuaj thiab raug nqi ntau dua li kev hloov kho tus qauv. Qee qhov teeb meem tsim qauv kuj tseem tsis tuaj yeem hloov pauv, ua rau qhov kawg rau kev cog lus lossis kev tsim khoom nrog cov teeb meem. Nyob rau theem no, qhov mob yog nyob rau hauv cov leeg. Hmoov zoo, tus neeg siv khoom tau muab sijhawm rau peb rau kev sim pwm thiab kev hloov kho, yog li peb tseem muaj sijhawm los kho cov pwm.
Thaum kawg, yog tias cov teeb meem pwm tsis raug daws nyob rau hauv cov qauv tsim, tsis yog nyob rau hauv qhov kev sim thiab kuaj cov theem, thiab hloov pauv thiab rub mus rau theem tsim khoom, qhov ntawd ua teeb meem. Thaum lub sijhawm no, cov pwm tau tsim, kev sim thiab kev hloov kho cov theem tsis tuaj, thiab cov sijhawm xa khoom xa tuaj yog nruj. Nws tuaj yeem hais tias tsuas yog ob lub qhov rais kho mob tau ploj lawm. Qhov no thaum kawg ua rau ncua cov khoom xa tuaj vim muaj teeb meem pwm, txo lub tuam txhab kev ntseeg siab thiab ua rau poob kev txiav txim yav tom ntej. Nyob rau lub sijhawm no, tus tsim thiab R & D departments, ntshai tsam raug lawv qhov txhaum, tuaj yeem hloov kev liam rau kev tsim khoom. Tsis tsuas yog ua cov teeb meem tsis tau daws, tab sis kev tsis sib haum xeeb hauv tuam txhab kuj tseem muaj zog. Nyob rau theem no, tus mob yog nyob rau hauv cov pob txha pob txha.
Niaj hnub no, kuv tau tshaj tawm lub tswv yim DFM rau cov khoom tsim thiab pwm tsim. Txhua tus neeg yuav tsum xub muaj lub tswv yim no hauv siab. Raws li rau cov teeb meem tshwj xeeb hauv cov khoom lag luam thiab pwm tsim uas ua rau qhov kev txhaj tshuaj molding tsis xws luag, kuv yuav muab cov ncauj lus kom ntxaws ntxaws hauv cov tshooj tom ntej ntawm kev txhaj tshuaj molding tsis xws luag thiab kev tiv thaiv, raws li qhov tsis xws luag.
