Kwicandelo lokwenziwa kweefowuni ezikrelekrele, ukuchaneka kokusikwa kweglasi kubaluleke kakhulu, kwaye isiseko segranite siba ngumdlali ophambili ekuqinisekiseni oku kuchaneka. Ngenxa yeempawu zayo ezikhethekileyo zezinto kunye nokusetyenziswa kwayo okuphambili kwezobuchwepheshe, ifikelela ekuchanekeni kokubekwa okuphindaphindiweyo kwe-±0.5μm, nto leyo ezisa ukuchaneka okugqwesileyo ekusikweni kweglasi kweefowuni ezikrelekrele.
Iingenelo zezinto eziphathekayo zibeka isiseko sokuchaneka
I-Granite inomlinganiselo ophantsi kakhulu wokwandiswa kobushushu. Olu phawu lwenza ubungakanani bayo butshintshe kancinci xa ubushushu butshintsha. Ngexesha lenkqubo yokusika iglasi kwiifowuni eziphathwayo, ukusebenza kwezixhobo kuvelisa ubushushu, kwaye ubushushu obujikeleze umhlaba bunokutshintshatshintsha. Isiseko sezinto eziqhelekileyo sinokutshintsha ngenxa yokwanda kobushushu kunye nokucutheka, okuchaphazela ukuchaneka kokusika. Isiseko se-granite sinokucinezela ngempumelelo olu tshintsho kwaye siqinisekise uzinzo lweendawo ezinxulumene necandelo ngalinye lesixhobo sokusika. Umzekelo, ngexesha leeyure ezininzi ezilandelelanayo zemisebenzi yokusika enamandla aphezulu, nokuba ubushushu bangaphakathi besixhobo bunyuka nge-10℃, utshintsho lobukhulu besiseko se-granite lunokulawulwa kwinqanaba le-nanometer, ngaphandle kokuphazamisa ukuchaneka kokusika.
Ukongeza, ulwakhiwo lwangaphakathi lwegranite luxinene kwaye lufana, lunobunzima obuphezulu, kwaye lunokumelana okuhle kokungcangcazela kunye nokumelana nokuguguleka. Ukungcangcazela okuveliswa ngexesha lenkqubo yokusika kunye nokungqubana kwezinto ezifana neereyile zesikhokelo ngexesha lokusetyenziswa ixesha elide zombini kunzima ukubangela umonakalo omkhulu kwisiseko segranite. Ingafunxa kwaye ithintele ukungcangcazela kwangaphandle, ithintele ukungcangcazela ukuba kungadluliselwa kwisixhobo sokusika, iqinisekise inkqubo yokusika egudileyo, kwaye idale indawo yokusebenza ezinzileyo yokufikelela kwindawo ephindaphindwayo ngokuchanekileyo.
Ixhaswa ziinkqubo zokuvelisa ezichanekileyo
Ngeendlela zokucubungula eziphambili, izalathisi eziphambili ezifana nokuthe tye kunye nokuthe tye kwesiseko segranite zilawulwa ngaphakathi koluhlu oluncinci kakhulu. Ngexesha lokucubungula, iindlela zokugaya nokupolisha ezichanekileyo ziyasetyenziswa ukuze kufezekiswe umgangatho ophezulu kakhulu wokuthe tyaba kumphezulu wesiseko, kunye nokunyamezela ukuthe tyaba okulawulekayo ngaphakathi kwe-±0.5μm. Ngale ndlela, iireyile zesikhokelo zezixhobo zokusika ezifakwe kwisiseko zinokugcina intshukumo echanekileyo yomgca, zibonelela ngesiseko esithembekileyo sokubeka ngokuchanekileyo intloko yokusika.
Okwangoku, ngexesha lenkqubo yokuhlanganisa isiseko kunye nezinye izinto zezixhobo zokusika, kusetyenziswe iindlela zokubeka ngokuchanekileyo kunye nokubopha. Indawo nganye yokudibanisa ilinganiswe ngokuchanekileyo ukuqinisekisa iindawo ezichanekileyo phakathi kwezinto. Ngokufaka iiphini zokuncamathisela kunye nokubeka iibholithi ngokuchanekileyo, intloko yokusika, indlela yokudlulisa, njl.njl. ziqhagamshelwe ngokusondeleyo kwisiseko segranite, zisusa naziphi na izikhewu kunye nokungakhululeki okunokwenzeka, ngaloo ndlela kuqinisekiswa ukuchaneka ngexesha lokubeka ngokuphindaphindiweyo.
Iinkqubo zokuqonda nokulawula eziphambili zisebenza ngokulungelelaniswa
Ukuze kufezekiswe ukuchaneka kokubekwa okuphindaphindwayo kwe-±0.5μm, isiseko segranite sikwadityaniswe nzulu neenkqubo zokuqonda kunye nokulawula eziphambili. Izinzwa zeendawo ezichanekileyo ezifana nee-grating rulers okanye ii-magnetic grating rulers zifakiwe kwizixhobo zokusika. Zijonga indawo yentloko yokusika ngexesha langempela kwaye zongeze idatha kwinkqubo yolawulo. Xa intloko yokusika igqiba isenzo esinye sokusika kwaye ilungele indawo elandelayo yokubekwa okuphindaphindwayo, inkqubo yolawulo iya kuthelekisa idatha ebuyiselwe yi-sensor nendawo ekujoliswe kuyo emiselweyo.
Nje ukuba kufunyenwe ukuphambuka kwindawo, inkqubo yolawulo iya kukhupha umyalelo wokuqhuba i-servo motor echanekileyo kakhulu ukuze ilungelelanise indawo yentloko yokusika. Yonke le nkqubo igqitywa ngexesha elifutshane kakhulu, ivumela intloko yokusika ukuba ilungiswe ngokukhawuleza nangokuchanekileyo kwindawo ekujoliswe kuyo, ifezekise ukuchaneka kokuphinda indawo ye-±0.5μm. Ngaphezu koko, le nkqubo yolawulo evaliweyo inokufunda rhoqo kwaye iphucule. Njengoko ixesha lokusetyenziswa lisanda, ukuchaneka kunye nokuzinza kokuphinda indawo kuphucuka ngakumbi.
Kwicandelo lokusika iglasi kwiifowuni ezikrelekrele, iziseko zegranite ziphumelele ekufumaneni ukuchaneka kokubekwa okuphindaphindwayo kwe-±0.5μm ngenxa yeenzuzo zazo zezinto ezibonakalayo, iinkqubo zokuvelisa ezichanekileyo, kunye nesiphumo sokusebenzisana kweenkqubo zokuqonda nokulawula eziphambili. Oku akupheleli nje ekuphuculeni umgangatho kunye nokusebenza kakuhle kokusika iglasi kwiifowuni ezikrelekrele, kodwa kukwabonelela ngenkxaso enamandla kuphuhliso oluchanekileyo lweshishini lonke lokuvelisa iifowuni ezikrelekrele.
