Kunzwisisa zvinhu zvikuru zvinokonzeresa mari kunobatsira pakuita sarudzo yekudyara neruzivo.
Mutengo wacho unonyanya kukonzerwa nezvinhu zvitatu zvehunyanzvi. Chekutanga, hukuru hwacho nehuremu hwacho—maplate makuru anoda kubatwa kwakaoma panguva yekurongedza uye kuwana zvinhu zvakawanda. Chechipiri, giredhi rekururama rinodiwa—maplate akasimbiswa kuti ave neGrade yepamusoro (AA, kana giredhi remurabhoritari) anoda maawa akawanda ebasa kubva kune vane hunyanzvi hwemetrology. Basa iri rakanyanya hunyanzvi, rinotora nguva yakawanda ndiro chikamu chakakosha chemusiyano wemitengo pakati pekamuri rezvishandiso (Giredhi B) neplate huru yemurabhoritari (Giredhi AA). Chekupedzisira, kuiswa kwezvinhu zvakagadzirwa, zvakaita sesimbi dzakasanganiswa dzakagadzirwa kuti dzibatanidzwe, T-slots dzakakuyiwa dzakanyatsogadzirwa kuti dzigadziriswe, kana kuti relief yemukati memukati kuti ideredze huremu uku ichiramba yakasimba, zvese zvinobatsira mukudyara kwekupedzisira.
Zvinonyanya kukosha ndezvokuti, puratifomu isina kururama kana kuti isina kugadzikana—kazhinji kacho nekuda kwekutenga modhi yakachipa, isina chitupa—inotungamira zvakananga mukugadzirwa kwezvikamu zvisingaenderane nezvinodiwa. Mutengo unotevera wezvakaraswa, kugadziriswa patsva, kudzoserwa kwevatengi, uye kurasikirwa nezvitupa zveindasitiri kunopfuura musiyano wemutengo wepuratifomu yegranite ine chitupa, yepamusoro-soro. Nokudaro, kuona mari yekutanga seinishuwarenzi inogara kwenguva refu inopesana nehunhu husina kunaka uye kusava nechokwadi kwehukuru kunopa maonero akakodzera ehupfumi.
Tafura yeGranite Surface yekuongorora seAsset Strategic
Tafura yepamusoro pegranite yekuongorora, pasina mubvunzo, ndiyo moyo wechero rakavimbika rekutonga mhando (QC) kana rabhoritari yemetrology. Basa rayo guru nderekupa puratifomu yakakwana, isina kutsauka yemidziyo chaiyo senge mageji ekukwirira, zviratidzo zvekudhirowa, zvinoenzanisa zvemagetsi, uye, chinonyanya kukosha, hwaro hweCoordinate Measuring Machines (CMMs).
Semuenzaniso, kururama kwekuverenga kuri nyore kwegeji yehurefu kunoenderana zvakanyanya nekutsetseka uye sikweya kweplate yepamusoro pachayo. Kana plane yekutarisa ine bow diki, isina kurongwa kana twist, kukanganisa ikoko kwejometri kunotamiswa zvakananga uye kunoiswa mukuverenga kwega kwega kunotevera, zvichitungamira kune systemic measurement bias. Maitiro ekuongorora akajairika anovimba neplate kuti ipe essential zero reference plane, zvichibvumira kuyerwa kwakavimbika ne master gauge blocks kana standards. Inoshandawo se primary datum establishment point, planar reference iyo zvese zviri pa critical workpiece zvinoyerwa. Uyezve, mumashandisirwo epamusoro-soro, huremu hukuru hwe granite flat surface table hunoshanda se stable, anti-vibration mount yeCMMs kana laser trackers, zvichiita kuti kunyangwe zvikanganiso zvidiki zvekunze kana zvemakanika hazvikanganisi kuyerwa kwe sub-micron level kuri kuitwa.
Kuti ndiro irambe yakasimba sechishandiso chekuongorora, inofanira kutsigirwa nemazvo. Chigadziko chehunyanzvi, chakagadzirwa nechinangwa chinhu chakakosha, chakagadzirirwa kubata ndiro panzvimbo dzinoderedza kushushikana dzakaverengerwa nemasvomhu (dzinozivikanwa senzvimbo dzemhepo). Kuisa ndiro yakanyatsogadzirwa pabhenji rebasa risina kurongwa, rinogadziriswa rinokurumidza kukanganisa kutsamira kweplate uye kunoita kuti metrology yese isavimbike. Sisitimu yekutsigira inowedzera kururama kweplate.
Kuramba Wakavimbika Kuburikidza neCalibration
Kunyange zvazvo kugara kwenguva refu kwetafura yegranite yakatsetseka kwakasimbiswa zvakanaka, haisi kukanganiswa nemamiriro ezvinhu akaoma ekushandiswa nguva dzose. Kunyangwe zvinhu zvakasimba zvakanyanya zvinogona kusakara zvishoma, munzvimbo imwe chete. Kuchengetedza kwakakodzera kwakakosha uye kwakatwasuka: nzvimbo yacho inofanira kucheneswa zvakanaka, isina guruva rinokuvadza, marara anopwanya, kana zvisaririra zvinonamira zvinogona kukanganisa zvishandiso zvekuyera. Zvinochenesa mapuratifomu epamusoro chete, zvisingakuvadzi, ndizvo zvinofanirwa kushandiswa. Njodzi huru pakusatsetseka kwepuratifomu inobva mukusakara kwakasimba, ndosaka mainjiniya vachikurudzirwa kushandisa huwandu hwese hwenzvimbo pane kungotarisa zviyero munzvimbo imwe chete diki.
Zvisinei, nzira chete yekuchengetedza mari iyi ndeyekuongorora nguva nenguva. Maitiro aya anoramba achidzokororwa, ayo anofanira kuverengerwa mumutengo wegranite surface plate kwenguva refu, haagone kutaurwa nezvawo kuti arambe achitevedzera mitemo yepasi rose yemhando yepamusoro. Munguva yekuongorora, nyanzvi yemetrology inotenderwa inoshandisa zvishandiso zvepamusoro, zvakaita semagetsi akakodzera kana michina yelaser, kuti iongorore nzvimbo yese. Vanoona kuti kutsamira kweplate, kudzokororwa kwayo munzvimbo dzakasiyana, uye kutsamira kwayo munzvimbo dzakasiyana kunoramba kwakavimbika mukati mechiyero chayo. Maitiro aya ekudzokororazve ekusimbisa anoona kuti plate inochengetedza simba rayo sechiyero chekuyera chakavimbika chenzvimbo, ichichengetedza mhando yechigadzirwa chega chega chinopasa kuongororwa.
Mumusika wepasi rose une makwikwi, vagadziri vanogara vachigadzira zvikamu mukati memvumo vane mitengo yakaderera yezvimedu, vimbiso shoma dzewaranti, uye kugutsikana kwakanyanya kwevatengi.
