Nzvimbo yekugadzira yemazuva ano inotsanangurwa nekuomarara kwesimba: otomatiki inomhanya zvakanyanya, mhinduro ye sensor yenguva chaiyo, uye maoko erobhoti anotungamira hungwaru hwekugadzira. Asi, pakati penzvimbo iyi yetekinoroji pane chokwadi chimwe chete, chisingachinji, uye chisingachinji: Granite Metrology Table. Nzvimbo iyi huru yekutarisa, inowanzova plate yegranite ine hunhu hwakasviba, inoramba iri chiyero chepamusoro chinotongwa nekururama kwese kwese.
Kuvimba kwakasimba kuri kuenderera mberiZvishandiso zvekuyera GraniteMumaindasitiri epamusoro-soro—kubva pakugadzira semiconductor kusvika kundege—hachisi chiratidzo chetsika, asi kubvuma kwakadzama kwefizikisi yezvinhu. Kana masisitimu achida kururama kusvika pa nanometer, nheyo pachayo inofanira kunge isina chainopomerwa, iine kugadzikana uko hakuna sisitimu yemagetsi inoshanda inogona kutevedzera zvakakwana.
Fizikisi Isingachinji yeGranite
Dambudziko guru mu metrology yakanyatsojeka nderekuparadzanisa kuyerwa kubva kuruzha rwezvakatipoteredza. Ruzha urwu rwunoonekwa mumhando mbiri dzinoparadza: kupisa kuyerera uye kudedera kwemagetsi.
1. Kukunda Kupisa Kwemhepo
Chikonzero chikuru chekukanganisa kwehukuru hwechinhu munzvimbo yekugadzira ikushanduka kwetembiricha. Kana zvinhu zvapisa, zvinokura; kana zvatonhora, zvinodzikira. Mwero wekuchinja uku unodzorwa neCoefficient of Thermal Expansion (CTE). Simbi, dzakadai sesimbi nesimbi yakakandwa, dzinoratidza maCTE akakwira. Kunyangwe kuchinja kudiki kwetembiricha kunogona kukonzera kuti simbi irambe ichichinja nema micrometer akati wandei - kutadza kushanda kamwe kamwe munyika ye sub-micron.
Granite nhema chaiyo ine CTE yakaderera zvakanyanya, zvichiita kuti igare yakasimba. Hunhu uhwu hunovimbisa kuti Granite Metrology Table inoramba yakatsetseka uye ine saizi yakatenderwa pasinei nekusiyana kwekupisa kwekunze. Uyezve, huwandu hwakawanda hwechinhu ichi hunoibvumira kupinza nekudzora kupisa zvishoma nezvishoma, ichishanda sechinodzivirira kupisa uye ichideredza kugadzikana kwekupisa nekukurumidza pamusoro payo.
2. Kuderedza Kusagadzikana Kwemakanika
Uriri hwese hwefekitori hunogona kudedera—kubva kumacompressor, maHVAC units, tsoka, uye traffic dziri kure. Kudedera uku, kunyangwe kazhinji kusingaonekwe nevanhu, kunogona kukanganisa nyore nyore kuyerwa kwelaser kana kukanganisa kurongeka kwechikamu chakarurama.
Granite inobudirira pano nekuda kwekugona kwayo kudzikamisa mukati. Kusiyana nesimbi, iyo inowanzo kurira kana kurira kana yarohwa, granite inokurumidza kudzima simba remuchina mukati. Kana mudziyo une resolution yepamusoro, senge CMM kana mudziyo wekutevera laser, ukaiswa paplate yegranite ine precision nhema, granite inoita kuti data rakayerwa riratidze geometry yechikamu, kwete ruzha rwekinetic rwenharaunda. Kusanganiswa uku kweCTE yakaderera uye kugona kukuru kwekudzimisa kunoita kuti granite ive yega passive material yakakodzera kushanda sehwaro hwezviyero zvinonyanya kudiwa pasi rose.
Tafura yeGranite Metrology: Kutsanangura Zero Plane
Chinangwa chikuru chekuongorora mativi ndichoTafura yeGranite Metrology, iyo inowanzo fananidzwa neplate yegranite yepamusoro-soro ine dema repamusoro. Iri harisi bhenji rinorema rekushandira chete; ipurani ye zero—nzvimbo yakatarwa, ine chitupa chekutarisa uko kuyerwa kwese kwemutsetse nekona kunobva.
Matafura aya akagadzirwa zvichienderana nezvinodiwa zvakanyanya, kazhinji achitevedzera mitemo yepasi rose yakaita seDIN 876, ASME B89, kana JIS B 7510. Kuyera kweplate yepamusoro (semuenzaniso, Giredhi 00, Giredhi 000) kunoratidza kutsauka kunobvumidzwa munzvimbo yese yekushanda. Magiredhi epamusoro anosvika pakureba kwakayerwa muma nanometers chete, basa guru rinongowanikwa chete kuburikidza nemaitiro ekupedzisira ekukotamisa.
Basa replate yepamusoro haringogumiri pakutsigira chikamu chete:
-
Kugadzira Datum: Inopa mutsetse we datum wakakodzera wekuongorora kwese kwejometri, ichiva nechokwadi chekuti zviyero zve parallelism, squareness, uye straightness zvese zvine chekuita nenzvimbo imwe chete, yakasimbiswa.
-
Kubatanidza Midziyo: Tafura iyi inoshanda sehwaro hwakagadzikana hwezvishandiso zvekuyera zveGranite (zvakaita semasikweya, maparallels, uye maV-blocks) pamwe nezvishandiso zvemhando yepamusoro zvakaita semagetsi uye laser interferometers.
Nzvimbo yeZvishandiso zvekuyera Granite
Purati yepamusoro ndiyo inosimbisa, asi kushanda kwayo kunovhurwa nehurongwa hweGranite Measuring Tools hwakaiswa pairi. Izvi zvinotsigira zvinobvumira kutamiswa kwakarurama uye kusimbiswa kwechokwadi chejometri.
-
MaGranite Parallels: Anoshandiswa kusimudza nekutsigira maworkpieces uku achichengetedza parallelism kana tichienzanisa neplate yepamusoro. Kugadzikana kwawo kunoita kuti divi rechikamu risakanganiswe panguva yekuyerwa.
-
Mabhuroko eGranite V: Anokosha pakugadzika zvinhu zve cylindrical (shafts, pins) uye kuona kuti axis ye cylindrical yakanyatsoenderana ne reference plane, danho rakakosha pakuyera zvinhu zvisingawanzoitiki uye kumhanya kwemvura.
-
MaGranite Tri Squares neMipendero Yakatwasuka: Sezvakakurukurwa mune dzimwe nzvimbo, zvishandiso izvi zvinotamisa kutwasuka kweplate kuita mativi akaenzana uye kutwasuka kwakakwana, zvichibvumira mainjiniya kuti vaone kuti mafambiro emuchina kana zvinhu zvakaunganidzwa zvakaenzana.
Kushandiswa nguva dzose kwegranite ine density yakakura pazvishandiso izvi zvese zvekuyera kunoderedza kusawirirana kwezvinhu uye kunoita kuti zviyero zvese zvienzane pakupisa uye kinetically.
Simba Risingazununguki reUnyanzvi hweUnyanzvi uye Kutevedza
Kukwanisa kugadzira mapuratifomu makuru egranite ane hunyanzi hwepamusoro-soro nguva dzose kunoda mari kwete chete mumichina yepamusoro-soro—yakadai senzvimbo dzekugadzira CNC dzine simba guru uye magrinder emhando yepamusoro e6000 mm—asi zvakare muzvinhu zvevanhu. Danho rekupedzisira, rakakosha rekugadzira mapuratifomu epamusoro-soro rinoramba riri hunyanzvi hwehunyanzvi.
Vagadziri vanotungamira vanochengetedza vashandi venyanzvi vane maoko anogona kunzwa uye kugadzirisa kutsauka padanho re sub-micron, hunyanzvi hwakavandudzwa kwemakumi emakore. Unyanzvi uhwu hunozosimbiswa nekuzvipira kusingazununguki kuvimbiso yemhando. Zvese Zvishandiso zvekuyera Granite zvinofanirwa kusimbiswa uchishandisa michina (senge laser trackers uye mazinga emagetsi) iyo kururama kwayo kunoenderana nemazinga epasi rose emetrology (semuenzaniso, NIST, NPL, PTB). Iyi cheni inoenderera mberi yekuenzanisa inopa chivimbo chakazara chinodiwa nemaindasitiri uko kururama kwakaenzana nekuchengetedzeka, kushanda zvakanaka, uye tekinoroji yekubudirira.
Pfungwa inotungamira indasitiri iyi ndeyekuvimbika kusingachinji: "Bhizinesi rekuita nemazvo harigone kuve rinoda zvakawanda." Kuvapo kwenguva refu kweTafura yeGranite Metrology iri nyore, isingachinji muzvivakwa zvepamusoro-soro kunoratidza kuti kunyangwe michina ichiita basa rinoshanduka, chokwadi chejometri chinofanira kugara chichitsanangurwa nekugadzikana kwakanyarara, kusingachinji kwematombo.
