Kwiphulo elingapheliyo lokuvelisa izinto ezingenaziphene, ukuhlolwa kobukhulu kudla ngokuxhomekeke ekuthembekeni kobudlelwane be-angular kunye ne-perpendicular. Ngelixa ipleyiti yomphezulu ibonelela ngesiseko se-flatness, ukuqinisekisa ukuba iimpawu zomsebenzi zithe nkqo ngokupheleleyo kuloo plane kufuna isixhobo esikhethekileyo nesizinzileyo. Kulapho keisikwere segranite,kunye nomzala wayo ochanekileyo, i-granite tri square, ziqinisa indima yazo ebalulekileyo kwilebhu ye-metrology. Ezi zixhobo, kunye nezixhobo ezibalulekileyo ezifana nesiseko se-granite see-dial gauge stands, zimele isiqinisekiso esithuleyo sokuba imilinganiselo ye-angular iyahlangabezana nokunyamezelana okunzima kakhulu.
Kutheni iGranite Ilawula Izixhobo Zokubhekisela Kwimilinganiselo
Ukukhetha igranite—ingakumbi i-diabase emnyama enobunzima obuphezulu—kwezi zixhobo yinto efunekayo emzimbeni. Ngokungafaniyo nezikwere zentsimbi okanye iiparallels zesinyithi esityhidiweyo, igranite inika indibaniselwano eyahlukileyo yezinto ezizinzayo ezenza ukuba ibe yeyona nto ibalaseleyo yokuqinisekisa inyaniso yejometri:
-
Uzinzo Lwemilinganiselo: I-Granite ine-Coefficient of Thermal Expansion (CTE) ephantsi kakhulu, oko kuthetha ukuba ukushukuma okuncinci kobushushu kwindawo yelebhu akubonisi ukuphambuka kwejiyometri okulinganisekayo. Isikwere sesinyithi, ngokuchaseneyo, sinokugoba kancinci, sinciphise i-engile ebalulekileyo ye-90-degree.
-
Ukumelana Nokunxiba Okurhabaxa: Xa izixhobo zokulinganisa okanye izinto zokusebenza zityibilika kumphezulu wegranite, izinto ziyaguga ngokuqhekeka ngemicroscope endaweni yokuguquka okanye ukuqhekeka. Le ndlela iqinisekisa ukuba umphetho okanye ubuso obubalulekileyo bugcina ukuchaneka kwejometri ixesha elide.
-
Ukufunxwa kokungcangcazela: Ulwakhiwo lwendalo oluyikristale kunye noxinano lwegranite luthintela ngempumelelo ukungcangcazela kokusingqongileyo. Oku kubaluleke kakhulu xa kujongwa ii-angular ezinobuthathaka kakhulu, ukuqinisekisa ukuba umlinganiselo uzinzile kwaye uthembekile.
Ukuqinisekiswa kwesikwere segranite kuthetha ukuba siqinisekisiwe ukuba singaphakathi kwee-intshi ezimbalwa ze-perpendicularity (squareness) egqibeleleyo kuyo yonke ubude baso bokusebenza, okuqinisekisa indima yaso njengesalathiso esichanekileyo sokulungelelaniswa kwezixhobo zomatshini kunye nokuhlolwa kwemveliso.
Indima kunye nomsebenzi weGranite Tri Square
Nangona isikwere segranite esiqhelekileyo sidla ngokuba nobuso obubini obuphambili obuthe nkqo, isikwere segranite tri sithatha ireferensi ye-angle echanekileyo inyathelo eliya phambili. Esi sixhobo sikhethekileyo sinobuso bomhlaba obune, obuhlanu, okanye obuthandathu obuchanekileyo obenziwe ukuba bube bukhulu ngokulinganayo. Le geometry yenza ukuba ibe sisixhobo esigqibeleleyo sokujonga ulungelelwaniso loomatshini—njengeziko loomatshini ezithe nkqo okanye ii-CMM—apho kufuneka ukujonga ukufana kunye nokuthe nkqo kwii-axes ezininzi.
Ukusebenzisa isikwere se-granite tri kuvumela iinjineli ukuba zenze uvavanyo olupheleleyo lwejometri yomatshini olungenakukwazi ukusingathwa sisikwere esilula. Umzekelo, kwiseti ye-CMM, isikwere se-tri singabekwa kwipleyiti yomphezulu ukuqinisekisa ukuba i-Z-axis imile ngokwenene kwi-XY plane, kwaye ngaxeshanye ijonge ukufana kweendlela ezithe nkqo. Ukuchaneka okuphezulu kunye nokuzinza kwe-tri-square kuthintela naluphi na ukungabaza malunga nomgangatho wesalathiso, kwahlula nayiphi na impazamo elinganisiweyo kwisixhobo somatshini ngokwaso endaweni yesixhobo sokuhlola. Ifumaneka ngobukhulu obahlukeneyo, isikwere se-tri sibalulekile ekufezekiseni amanqanaba aphezulu okuchaneka kwe-angular afunekayo kumashishini afana ne-aerospace kunye nokuveliswa kwezixhobo zonyango.
Ukuzinzisa Ukufunda: Isiseko seGranite seDial Gauge Stands
Ukuchaneka kwi-dimensional metrology akupheleli nje kwireferensi; kukwamalunga nokuzinza kwesixhobo sokulinganisa ngokwaso. Isiseko segranite see-dial gauge stands kunye nee-height gauges sisebenza njengonxibelelwano olubalulekileyo phakathi kwesixhobo sokufunda kunye nepleyiti ephambili yomphezulu.
Kutheni kusetyenziswe isiseko segranite endaweni yesesinyithi? Impendulo ikubunzima kunye nokuzinza. Isiseko esikhulu segranite sinika ukuqina okuphezulu kunye nokunciphisa ukungcangcazela kwe-gauge stand, ukuqinisekisa ukuba iintshukumo ezincinci okanye ukungcangcazela kwangaphandle akuguquleli ekuguqukeni okungalunganga kwisalathisi se-dial. Ngaphezu koko, ukuthamba okungokwemvelo kwesiseko ngokwaso kuqinisekisa ukuba ikholamu ye-gauge ibanjwe ngokuthe nkqo kwipleyiti yomphezulu kuyo yonke ihambo yayo. Oku kubaluleke kakhulu kwiimilinganiselo ezithelekisayo, apho i-dial gauge kufuneka ilandelele uphawu kumgama, kwaye naluphi na ulwalwa oluncinci okanye ukungazinzi kwisiseko se-stand kuya kungenisa impazamo ye-cosine okanye ukuthambekela ekufundeni. Uzinzo olunikezelwa yisiseko segranite esakhelwe injongo yezixhobo ze-dial gauge luphucula ukuphindaphindwa kunye nokuzithemba kwayo yonke imilinganiselo ethathiweyo.
Utyalo-mali kwiNgqibelelo yeJiyometri
Ixabiso lezi zixhobo zokubhekisela kwigranite, nangona ziphezulu kunezinye zesinyithi, libonisa utyalo-mali olufanelekileyo kwi-geometric integrity. Ezi zixhobo zihlala ixesha elide kakhulu, ukuba nje ziphathwa kwaye zigcinwe ngokuchanekileyo. Azigqwali, kwaye iimpawu zazo zokuguguleka ezigqwesileyo zithetha ukuba isiqinisekiso sazo sokuqala sokuchaneka sihlala sithembekile kangangeminyaka, ngokufuthi amashumi eminyaka.
Eyona nto ibalulekileyo ekufuneka iqwalaselwe yindleko yempazamo. Ukuthembela kwisikwere sentsimbi esingaqinisekiswanga okanye kwi-stand ye-metal gauge engaguqukiyo kunokukhokelela kwiimpazamo ze-angular zenkqubo kwiindawo ezivelisiweyo. Oku kukhokelela ekusetyenzisweni ngokutsha okubiza kakhulu, ukwanda kwezinto ezilahliweyo, kwaye ekugqibeleni, ukulahlekelwa kukuzithemba kwabathengi. Ukutyala imali kwisikwere se-granite tri esiqinisekisiweyo sokulungelelanisa umatshini kunye nokusebenzisa isiseko se-granite esithembekileyo kwii-stand ze-dial gauge kunciphisa le mingcipheko ngokubonelela ngendawo yokubhekisa ecacileyo nezinzileyo.
Ngamafutshane, isikwere segranite kunye nezixhobo zaso zemetrology azizozinto nje ezincedisayo; zimigangatho engenakuphikiswana eqinisekisa ukuba inkqubo yokwenziwa kwayo imile nkqo. Zizii-alindi ezithuleyo zokuchaneka kwe-angular, eziqinisekisa ukuba izinto eziphuma kumgangatho wevenkile ziyahlangabezana neempawu zejometri ezifunekayo kushishino lwanamhlanje.
