Granite Surface Phaj Raws li ASME

Cov phaj saum npoo yog ua los ntawm ntau hom granite - lawv loj, tawv, thiab tawv. Sab saum toj ua hauj lwm nto yog lapped tiaj tus thiab du los muab ib qho tseem ceeb siv nto rau ntau hom kev ntsuas qhov ntev. Qhov zoo ntawm daim hlau saum npoo tau raug qauv rau ntau xyoo dhau los ntawm Tsoom Fwv Teb Chaws Specification GGG-P-463c. Cov ntaub ntawv ntawd tau ua tsis muaj zog hauv 2013 thaum ASME B89.3.7 tus qauv tau tshaj tawm. Feem ntau ntawm cov ntsiab lus ntawm GGG-P-463c, suav nrog cov qhab-nees tus qauv thiab tus nqi kam rau ua, tau tso tseg tsis hloov pauv thiab hloov mus rau tus qauv tshiab.

Qhov tseeb Specifications

Lub hom phiaj ntawm cov ntawv tshaj tawm kev tshaj lij no yog cov phaj saum npoo av flatness, uas yog qhov tseem ceeb tshaj plaws ntawm cov qauv ntsuas ntawm cov phaj saum npoo thiab yuav raug calibration raws sij hawm. Raws li ASME B89.3.7 tus qauv, muaj ob qhov sib txawv flatness yam ntxwv tseem ceeb - tag nrho flatness, uas npog tag nrho cov chaw ua hauj lwm nto, thiab lub zos variation nyob rau hauv flatness, uas yog tseem hu ua rov qab nyeem ntawv. Qhov sib txawv hauv zos hauv flatness siv rau thaj tsam me me ntawm cov phaj saum npoo thiab yog li ntawd yuav ib txwm muaj qhov sib haum me me dua li qhov flatness tag nrho. Rau ob qho tib si cov yam ntxwv, tib lub ntsiab lus ntawm flatness siv - nws yog qhov kev ncua deb ntawm ob lub dav hlau sib luag uas muaj tag nrho cov ntsiab lus ntawm lub phaj. Hauv kev xyaum, flatness yog ntsuas los ntawm kev ntsuas cov ntsiab lus thoob plaws qhov chaw thiab txiav txim siab qhov kev ncua deb, lossis ntau yam, los ntawm qhov siab tshaj plaws mus rau qhov qis tshaj.

ASME B89.3.7 txhais cov qauv kev kam rau siab rau cov phaj saum npoo. Cov phaj siab tshaj plaws yog hu ua Qib AA, thiab lawv feem ntau pom muaj nyob rau hauv cov chaw soj ntsuam calibration. Qib B daim hlau yog cov phaj qis tshaj plaws, thiab lawv tuaj yeem pom nyob rau hauv cov khw hauv tsev. Cov phaj nruab nrab, Qib A, feem ntau siv rau hauv qhov chaw soj ntsuam. Cov phaj saum npoo feem ntau yog tsim nyob rau hauv ntau qhov ntau thiab tsawg thiab ua raws li cov qauv ntsuas. Cov neeg siv khoom tuaj yeem xaj qhov loj thiab qhov zoo ntawm cov phaj xav tau. Cov lus hauv qab no teev cov kev kam rau siab rau tag nrho cov flatness thiab lub zos variation hauv flatness rau peb qib sib txawv raws li tau teev tseg hauv ASME B89.3.7 tus qauv.

Calibration thiab Verification

Nyob rau hauv kev xyaum, tag nrho cov flatness thiab lub zos variation nyob rau hauv flatness yuav tsum tau calibrated rau ib tug nto phaj. Calibration ua los ntawm kev tshuaj xyuas kev sib haum xeeb ntawm cov phaj saum npoo rau ob qhov sib txawv ntawm qhov sib txawv. Yog tias tsim nyog, kev hloov kho rau saum npoo phaj flatness - feem ntau ntawm qhov chaw rov lapping - tuaj yeem ua tau los ntawm cov neeg uas xav tau kev txawj ntse thiab cov cuab yeej.

Tag nrho cov flatness feem ntau kuaj nrog lub laser interferometer, autocollimator, hluav taws xob theem, los yog tus tswv ncaj nraim thiab qhov taw qhia. Rau tag nrho cov txheej txheem no, cov kab ntsuas kab thoob plaws lub phaj saum npoo yog tsim thiab tom qab ntawd cov kab sib xyaw ua ke rau hauv peb qhov kev ntsuam xyuas ntawm tag nrho cov flatness.

Qhov kev hloov pauv hauv zos hauv kev tiaj tus, lossis rov nyeem dua, feem ntau yog kuaj xyuas siv qhov hu ua rov nyeem ntawv gage. Qhov ntsuas ntsuas no muaj peb lub hauv paus me me txuas nrog rau qhov pivoting nrog rau qhov chaw thib plaub. Qhov taw qhia yog siv los ntsuas qhov ntsug txav ntawm plaub taw tes txheeb ze rau lub hauv paus. Qhov rov nyeem ntawv gage yog manually swept nyob ib ncig ntawm lub phaj nto, thiab ntsuas lub zos variation nyob rau hauv flatness yog qhov ntau ntawm qhov taw qhia txav.
