Tolerances thiab precision nyob rau hauv manufacturing: dab tsi yog nws thiab yuav ua li cas ua tau nws?

Kev kam rau siab yog qhov tso cai sib txawv ntawm qhov ntev, cov duab, qhov chaw thiab lwm yam tsis muaj ib feem lossis kev sib dhos los ntawm cov nqi nominal tsim los ntawm cov duab kos lossis cov lus qhia tshwj xeeb. Qhov tseeb yog qhov degree uas qhov tseeb qhov tseem ceeb ntawm cov khoom tsis sib xws rau lawv cov nqi nominal. Nyob rau hauv tsab xov xwm no peb yuav saib seb qhov kam rau ua yog dab tsi thiab yuav ua li cas kom ua tiav qhov tseeb hauv kev tsim khoom.

Hom kam rau ua
Muaj ntau ntau hom kev kam rau siab uas siv nyob ntawm seb hom kev tsim khoom thiab cov khoom yuav tsum tau ua. Hom kev pom zoo tseem ceeb muaj xws li:

Dimensional tolerances: Cov no yog qhov tso cai sib txawv ntawm qhov ntev ntawm qhov chaw los ntawm cov nqi nominal.
Puab tolerances: cov no yog qhov tso cai sib txawv ntawm cov duab ntawm qhov chaw los ntawm cov duab nominal.
Qhov chaw kam rau ua: cov no yog qhov tso cai sib txawv ntawm qhov chaw ntawm qhov chaw ntawm qhov sib txheeb.
Roughness tolerances: Cov no yog qhov tso cai sib txawv ntawm qhov roughness ntawm qhov chaw los ntawm nominal roughness.
Yuav ua li cas mus cuag high precision nyob rau hauv ntau lawm?
Yuav kom ua tiav high precision hauv kev tsim khoom, cov hauv qab no yuav tsum tau ua raws:

Siv cov cuab yeej zoo: Siv cov cuab yeej siv niaj hnub nrog kev ua haujlwm siab thiab kev ntseeg siab yuav pab ua kom tiav siab precision hauv kev tsim khoom.
Kev Tswjhwm Zoo: Kev tswj xyuas qhov zoo ntawm txhua theem ntawm kev tsim khoom yuav pab txheeb xyuas qhov ua yuam kev thiab kho lawv ua ntej lawv ua rau cov khoom tsis raug.
Kev cob qhia cov neeg ua haujlwm: Kev cob qhia cov neeg ua haujlwm hauv kev siv cov cuab yeej kom raug thiab ua raws li cov txheej txheem thev naus laus zis yuav pab txhim kho cov khoom zoo.
Kev ua raws li kev tswj hwm zoo: kev ua raws li ISO 9001 kev tswj hwm zoo yuav pab tswj txhua qhov kev tsim khoom thiab ua tiav qhov siab ntawm txhua theem.

Hauv kev xaus, kev tsim kev kam rau siab thiab precision yog qhov tseem ceeb ntawm cov khoom zoo. Yuav kom ua tiav qhov raug siab, nws yog ib qho tsim nyog yuav tsum siv cov cuab yeej siv niaj hnub no, tswj xyuas kom zoo thiab cob qhia cov neeg ua haujlwm. Kev taw qhia txog kev tswj hwm zoo yuav pab tswj txhua qhov txheej txheem thiab ua tiav qhov tseeb ntawm txhua theem ntawm kev tsim khoom.
