Waisa mari muchina wekuyera wemazuva ano. Software yacho yakaongororwa. Maprobes ane certification. Asi, zviyero zvako zvinofamba-famba. Kwete zvakanyanya—micron chete pano, hafu micron ikoko. Asi munyika ye ultra-precision metrology, drift iyoyo ndiyo musiyano uripo pakati pekupasa nekukundikana, pakati pemhando yepamusoro ne rework, pakati pepurofiti ne scarc.
Chii Chinonzi Thermal Drift, Chaizvoizvo?
Kufamba kwekupisa kunoitika kana kusiyana kwekupisa kuchikonzera kuti zvikamu zvechimiro chesystem yekuyera zviwedzere kana kupfupika zvisina kuenzana.Zvikamu zveCMM—furemu, zvikero, nhungamiro, kana hwaro—zvichikura zvisina kuenzana, zvinounza kukanganiswa kwejometri kunotungamira kune zvikanganiso zvekuyera.
Dambudziko iri harionekwe nekuti harionekwe. Haugone kuona 9°C vertical temperature granite lintel, asi rinogona kuchinja urefu hwe granite linear pamwero weavhareji ye1 μm pa degree Celsius. Mu nanometer-level metrology, izvozvo zvinotyisa.
Kunyangwe tembiricha shoma inorayirwa murabhoritari yemetrology—kazhinji 20°C ± 0.5°C—inogona kukonzera kupisa kwakakwana muzvivakwa zvesimbi kuti zvikonzere kuyerera kwakanyanya. Simbi ine CTE kaviri kupfuura granite. Aluminium ine CTE yakapetwa katatu. Kana tembiricha yemukamuri ikatenderera—sezvainoita mune chero nzvimbo chaiyo—zvikamu zvesimbi zvinokura uye zvinokotama pamatanho akasiyana pane granite base, zvichigadzira kusava nechokwadi kwekuyera kunowanikwa mukuverenga kwega kwega.
Nei Granite Iri Chidziviriro Chekupisa
Mhinduro yacho haisi yekuwedzera simba rekugadzirisa tembiricha. Ihwaro risingafambi pakutanga.
CTE yakaderera zvikuru yeGranite inoderedza shanduko yehukuru, ichichengetedza hukama hwakakosha hwejometri pakati pemaaxes eCMM nechikamu chakayerwa. Granite yedu nhema yeZHHIMG®, ine density ye ≈3100 kg/m³, inopa kugadzikana kwekupisa kunopfuura magranite matema mazhinji ekuEurope neAmerica. Huremu hukuru hwekupisa hwegranite hunoshanda sechinodziya chekupisa chisina kusimba, ichideredza kushanduka kwekushisa uye ichichengetedza nzvimbo inodziya yehuwandu hwese hwekuyera.
Asi zvinhu chete hazvina kukwana. Nzvimbo yacho inokoshawo saizvozvo.
Kugadzira Nzvimbo Yakagadzikana Zvinopisa
KuZHHIMG®, tatora kugadzikana kwekupisa zvakanyanya kusvika padanho remaindasitiri. ...
Asi tinoenderera mberi. Tinochengetedza imba yekugezera ine tembiricha isingachinji uye ine hunyoro isingachinji iyo inotevedzera nzvimbo dzekugadzira michina ye semiconductor—yakagadzirirwa kusanganisa zvikamu zve granite. Izvi hazvisi zvekungochengetedza tembiricha iri pa20°C chete. Zvinoreva kubvisa kupisa kwakanyanya muzvikamu zvikuru panguva yakakosha yekugadzira: kuunganidza kwekupedzisira uye kuongorora.
Cheni Yekuyera
Ehe, haugone kudzora zvausingakwanise kuyera. Ndosaka lab yedu yemetrology yakashongedzerwa nezvishandiso zvekuyera zvepamusoro-soro pasi rose: maGerman Mahr dial gauges (0.5 μm resolution), maMitutoyo micrometers nema digital calipers, Swiss WYLER electronic levels, uye British Renishaw laser interferometers. Chishandiso chega chega chine zvitupa zve calibration kubva kuJinan Institute of Metrology neShandong Institute of Metrology—uye calibration yega yega yechigadzirwa inogona kuteverwa kudzokera kuNational Institute of Metrology of China.
Chinhu Chinoumba Munhu
Heino chimwe chinhu chisingakutaurirwi nemabhuku ekudzidza: kunyangwe michina yakanakisisa uye nzvimbo yakagadzikana zvakanyanya hazvigone kutsiva kutonga kwevanhu. Nyanzvi dzedu dzekugaya, imwe neimwe ine ruzivo rwemakore anopfuura makumi matatu ekubata nemaoko, dzinogona kuona kuti vari kubvisa mangani ma microns echinhu nekukasira kamwe chete. Vatengi vedu vanovati "vanofamba nemagetsi". Havangoteveri maitiro chete; vanonzwa chinhu chacho, vachinzwa shanduko dzekudzivirira dzinoratidza kusiyana kwe microscopic mu flatness.
Iyi nzira yekubata-bata—inobatanidza zvivakwa zvepasi rose nepfungwa dzevanhu dzisingatsiviwi—inoita kuti chikamu chega chega chegranite cheZHHIMG®, kubva pamapuratifomu epamusoro kusvika kumabheringi emhepo, chinosangana nezvinodiwa zvakanyanya pasi rose.
Mazano Anoshanda Kune Vatengi
Kana mutengesi akataura nezve "granite" asina kutaura kana iri dombo rakacherwa kana kuti mineral casting, bvunza zvakananga—musiyano wemutengo, geometry inogoneka, uye kugadzikana kwenguva refu kwakasiyana zvakakwana zvekuti musiyano wacho unofanira kuva chikamu chechero technical spec sheet. Kuti uwane metrology yakanyatsojeka, kumbira kuti density chaiyo, CTE, uye flatness tolerance yakawanikwa—kwete zita rechinhu chete.
Nekuti munyika yekuyera nanometer-level, thermal drift haisi dambudziko raunogadzirisa nesoftware compensation. Idambudziko raunodzivisa nezvinhu zvakakodzera, nharaunda yakakodzera, uye vanhu vakakodzera.
