Ukulungiselela Kwesitsha Kusidla Ukulinganisa Kwezilingo Nezidingo Zesimo

Kanjani ukulinganisa okungenani kumicroni eyishumi abili kukhupha ukugcina, ukudluliswa okuncane, nokuhluka kwesimo kumazitebhisi azima nezilanga

Ukugcina izipande ezilandelana ngendawo ebalaseleyo ngaphaya kwemifudukasi engu-2 ibonakala ngokugcwele uma kususwa izicathulo ngokucophelela. Uma zipande ziyekwa le mahlalela, zithwalela ingxenye engahlukileyo yesayiphi, okwakha umnyango kuzo zizindawo ezithile. Lezi zindawo zomnyango eziphakeme zibanza ukuthutha kanye nesithotho esincane, ikakhulu uma kubonakala kumadini amakhanda njenge porcelain kanye nezicathulo ze ceramic. Izipande ezithintela ngaphansi kwe-2 micrometers zibonakala ngokulandelana ngokugcwele kuyo yonke indawo yokususa, ngakho-ke akukho lutho olwakha umnyango ngaphandle kwalokho. Ngaleso sikhathi, izinhlangothi azizukwazi ukuthabatha ngaphezulu kwe-0.1 mm noma kususwa ngamandla angam 300 mm, into efana naleyo eyethulelwe yi-ANSI A137.1 ngokuthi yini efakwa njalo ngokwesilinganiso esivumelekile kumadini.

Ubuciko bokwenzayo: 2 µm ukuthabatha kwesilinganiso - 0.03 mm ukwahluka kwekerf ngokususwa ngamandla angu-600 mm (CTC Lab, 2023)

I-CTC Lab walwenza izivikelo ngo-2023 ebonisa ukuthi lapho kukhona inkinga yomgwebo othile obanzi ngama-2 micrometer, kuyakha ngempela ubude obuhluke ngama-0.03 mm kwi-kerf kule ncike enkulu eziningi kakhulu kuma-600 mm. Walibheka konke ngokulungiswa kwe-laser futhi wafundwa ukuthi lezinye izinkinga ezincane ziyajijimaza kakhulu ubunzima bokujika kwamagrating, ikakhulukazi emathikwini amahle aphathelene ngenhla lapho ubucophele buqondiswayo kakhulu. Lapho uhlinzelela izinombolo, ukulawula umgwebo kuze kube ngu-micron kususa okuphindwe kabusha kwemisebenzi ngabangu-20% ngexesha lokwenza izithuthi. Lokhu kuyakha uhlelo olubalulekile ngokusho kwalokho isikhathi esifunekayo sokwenza izinto ne-bukhona kwegunya eliphelile.

Ukulawula Kwemigwebo Ebanzi Ngemizuzwana Yomgwebo Kususa Ukuvibrata Kanti Kuyakhula Isimo Sezixhobo

Ukuqala Kwesono kanye Nokukhula Kwesono Kwesipindlana Ngaphezu Kwesono Ngama-5 µm Ngemvuzu Engu-8,000 (idatha ebechazwe yi-FFT)

Ukuphazamiseka kwegolide kungaphezulu kwe-5 microns ngenkathi kuyashisa kuma-8,000 RPM kuthinta into ethile ekhangelayo uma sibuka ngokusebenzisa ubonakaliso be-FFT. Okuthiwa kusenzeka kukuthi izivibrhesi ze-harmonic zakhelapha kakhudlwana, zenza amandla afihlakeleyo angase aphinde asebenze kakhulu kune-12.5 mm/s squared. Lo hlelo lomkhondo lubamba izinto kangakanani. Izigolide zizofika ekulodwa kwimvuselelo engalingani, okwenzela ukuthi izintamo ze-carbide ziphule ngaphambi kokuba kube yisikhathi. Amabharingi nawo ayohlwaya, ubude bokuphila kubo buhlatshelwa ngaproximately kuma-33%. Uyimfihlele futhi umba wokugcina - ofuna ukuphinda kuphinde kuqediswe kumathuba we-0.1 Ra. Ukugcina igolide isimama ngezansi kwe-5 microns kunceda kakhulu lapha. Kuyehlisa le mandla futhi kumemeza izinhlelo zomkhondo ukuthi azize njalo. Izigolide zilindela ngaproximately ama-40% ukuya kuma-50% angaphandle kwalokho. Izicutshiwa zilinda ezihlukile kanye neziphambene. Lokhu kubaluleke kakhulu kumsebenzi wama-porcelain angcono. Noma yiziphephetho eziphansi kakhulu zenza ububi obuchibiyo obuhlanzekayo obunika isimo esingcolile kanye nokuthi amanzi awusi phansi lapho asikufanele.

Ukugcina kweyofaca kuyaphilisa ekuthinteleni kweqhinga ne-tile esebenzisa ukugcina kweyophakade

Ubunzima bekuthinta kubuchwephesheleka >12% phambi kweqhinga uma iphakade iphumeze ±1.5 µm (ISO 1101 CMM ikhondla)

Ukufumana isandla esihle sokugcina sikhomba kakhulu ekugcineni ubude bokubamba kwiblade ngetile, okungadingeki ngaphandle kokulawula kahle ukulinganisa. Bheka okwenzekayo xa ukulinganisa kusuka ngaphezulu kwe-±1.5 microns ngokwalezi zinhlobo ze-ISO 1101 ezivikelwa yiimpendulo eziphazamisa izinto. Isathisho sobunzima siphindaphindwa kakhulu, ngamanye amaxesha sasiphinda ngaphezulu kwe-12% phakathi kwezinye iindlela zentonga yebhlade. Lokhu kuthetha ntoni? Kuya kusuka kusondele kwezi ziphumo apho iitile ziyakhala kwiinxalenye zonyango, ngelishwa ezinye iindawo zinobunzima obuncinci kakhulu okuba ibhlade ishamayi. Ezimbini izimo ziya kubangela ukuba iintambo zikhiwe nezigaba ezingaphantsi kakhulu ezinye iindawo kodwa ziphantsi kakhulu ezinye. Kubo bonke abasebenza kumisebenzi yokucinezela, ukulondoloza kule ntla ye-1.5 micron ayisiyona nto engcono kuphela kodwa ifuna kakhulu ukuba kwenzeke ukuze kube nenqanaba eliqinisekileyo yonke into.

Ukukhuluka kweglazi enzululwini: Kudingeka ukuthi kube nendimana engaphansi kuka-0.8 µm - kodwa 68% yamabhiladi esifundazini ishiyelela ±2.3 µm (Ukubuyekeza Kwesifundo sikaTCNA 2024)

Kumaqashi agcwele, amabhiladi kumele abe nenhlaka engaphansi kuka-0.8 microns ukuze akuvikele izikhaza ezincane eziphazanyiswa kusindlela xa kugcinwa. Kodwa ngokwesibonelo esisha sikaTCNA esihlinzekile ku-1,200 imithombo yesakhiwo ngo-2024, umbili ngamashumi ayisishiyagalombili wamabhiladi wayesezindaweni eziphazanyekile kakhulu ngaphezu kuka-2.3 microns yenhlaka. Lokhu kungaphezulu kweziphazanyo ezivunyelwe khona. Ukuphazanyeka phakathi koko okuchazwe yisimo nokho kusabalalwa emaphandleni kukhona ngokudala kwemfanelo engaphathelweni emthwebeni wokuletha. Uma abasebenzi bethembela iziphumo eziqinile ngaphandle kwezici zingavuseleki, kufanele bakhokhele emabhiladi abalwe ngolaser futhi babophele ukuthi kube nezibopho zobulandelayo kuzo zonke izinsiza zabo.

Ukulawula Kakhulu Kwenzima Yebhiladi Kudinga Izindlela Zokulinganisa Ezivunyelwe Ngokwesayensi Yokulinganisa

Ukulinganisa kwe-laser vs. i-CMM engaphakathi: ukucindezelana, ukubuyela emva, nokufaneleka kwempilo yamandla kumahluko angaphansi kwemikro

Ukuthola izilinganiso ezinembile kubaluleke kakhulu lapho uzama ukugcina indawo iphansi ezingeni elingaphansi kwe-micron. I-laser interferometry iyaphawuleka ngoba ayithinti indawo elinganiswayo, inikeza ukucaca okufinyelela kuma-nanometer ngokuphindaphindwa okungama-0.1 micrometers. Lobu buchwepheshe buthatha imininingwane ephelele yendawo ngaphandle kokulimaza lokho okuhlolwayo. Ngakolunye uhlangothi, imishini yokulinganisa ama-coordinate yendabuko (CMMs) incike ekuxhumeni ngokomzimba ngokusebenzisa izinhloli ezinamaphuzu ngokuvamile amakhulu kune-0.5 micrometers. Lezi zeluleko ezinkulu zingase zingakuboni ukushiyeka okuncane noma zishintshe ukufundwa ngokufaka umngcele endaweni. Nakuba ama-CMM engakwazi ukufinyelela ekuqondeni okungama-micrometer angu-1,5 noma ngaphansi ezindaweni ezilawulwayo zaselabhorethri, alwa kanzima ezimweni zangempela zasemabhizinisini lapho izinguquko zokushisa nokudlidliza kuphazamisa imiphumela. Lapho kuziwa ekufakeni ama-blade adinga ukucacisa okukhulu, izinhlelo ze-laser njalo zinikeza imiphumela engcono ephindaphindwayo, idatha ehlanzekile engenakho ukuhlanekezelwa, nokuhlola okungaphazamisi ingxenye elinganiswayo. Yingakho izitolo eziningi ziqala zisebenzise ama-laser ukuze zigcine ukunemba kokusika nokuqeda kahle.

Imibuzo Evame Ukubuzwa

Kungani ukulingana kwezansi-2 µm kubaluleke kakhulu ekugcwaliseni izinkulungwane?

Ukugcina ukulingana kwesiklakala kuzinzile-2 µm kumelapha ukwahlukanwa kwegunyana ezingavuthi izikhumba, izinkinga ezincane, nezinye iindlela zezinkulungwane, ukuqinisekisa ubumnandi nokufaneleka kweekhriteria ze-ANSI.

Ukulingana kwesiklakala kuthinta kanjani ubude bebusuku balesiklakala?

Ukulingana ozinzile 5 µm kumelapha izivivinyo eziphathelene, ukulawula igunya eliqinisekisa ubude bebusuku ngaphezu kuka-40-50%, ukuqinisekisa ukuba izigciso zilahle klare futhi zenze ngokuphelele.

Kungani ukulingana nge-laser kusiywa ngaphezu kwe-CMM yokulinganisa isiklakala?

Ukulingana nge-laser kunezidingo ezinezimali ezingaphansi kwe-nanometer engaqedi eliphelele, ukuqinisekisa ukulinganisa okuchanekile ngaphandle kokuthintana, ngasemva kwezilingo ze-CMM ezingathintana ezingashintsha izivakalelo.
