Iisistim zentshukumo zomgca - ezibandakanya isiseko okanye izindlu, inkqubo yesikhokelo, kunye nesixhobo sokuqhuba - zifumaneka kwiindidi ezahlukeneyo zoyilo kunye nokucwangciswa ukuze zihambelane phantse nasiphi na isicelo.Kwaye ngenxa yokuba uyilo lwazo lwahluke kakhulu, luhlala luhlelwa ngokwemigaqo engundoqo yokwakha kunye nokusebenza.Umzekelo: Igama elithi "i-actuator" ngokuqhelekileyo libhekisela kwisistim eshukumayo somgca kunye nendlu ye-aluminiyam evale isikhokelo kunye neendlela zokuqhuba;iinkqubo ezibizwa ngokuba “ziitafile,” okanye “iitafile zeXY,” zidla ngokuyilwa ngesiseko esisicaba apho isikhokelo kunye nezixhobo zokuqhuba zinyuswa khona;kunye “nesigaba somgca” okanye “inqanaba loguqulo lomda” ngokuqhelekileyo libhekisa kwisixokelelwano esifana nolwakhiwo kwitheyibhile yomgama kodwa eyilelwe ukunciphisa iimpazamo ekumiseni nasekuhambeni.
Iisistim zentshukumo zomgca zingabonisa iindidi ezintathu zeempazamo: iimpazamo zomgca, iimpazamo ze-angular, kunye neempazamo zeplani.
Iimpazamo zomgca ziziphoso ekumiseni ukuchaneka kunye nokuphinda-phinda, okuchaphazela ukukwazi kwenkqubo ukufikelela kwindawo oyifunayo.
Iimpazamo ze-angular - eziqhele ukubizwa ngokuba yi-roll, pitch, kunye ne-yaw - ibandakanya ukujikeleza malunga no-X, Y, kunye no-Z, ngokulandelelana.Iimpazamo ze-angular zingakhokelela kwiimpazamo ze-Abbé, eziziimpazamo ze-angular ezikhuliswe ngumgama, njengomgama phakathi kwesikhokelo somgca (umthombo wephutha le-angular) kunye nendawo yesixhobo sokulinganisa.Kubalulekile ukuqaphela ukuba iimpazamo ze-angular zikhona naxa iqonga lingashukumi, ngoko ke zinokuba nefuthe elibi kwimisebenzi engatshintshiyo efana nokulinganisa okanye ukugxila.
Iimpazamo zePlanethi zenzeke kwiindlela ezimbini - ukuphambuka ekuhambeni kwinqwelo-moya ethe tye, ekubhekiselwa kuyo njengento ethe tye, kunye nokuphambuka ekuhambeni kwinqwelomoya ethe nkqo, ekubhekiselwa kuyo njenge-flatness.
Nangona kungekho migaqo okanye izikhokelo ezingqongqo malunga nenqanaba lomgca, zibonwa ngokubanzi njengolona didi luchanekileyo lweenkqubo zentshukumo.Xa isixokelelwano sibhekiswa kuso njengenqanaba lomgca, kuqondwa ngokubanzi ukuba inkqubo ayizukubonelela ngokuchaneka kwendawo ephezulu kunye nokuphindaphinda, kodwa kunye neempazamo ezisezantsi ze-angular kunye neplani.Ukufezekisa le nqanaba lokusebenza, kukho imigaqo emininzi abavelisi abalandela ngokubanzi malunga nokwakhiwa kunye nohlobo lwamacandelo asetyenziswe kwisakhiwo sesiteji.
Esi sigaba somgca sisebenzisa iibheringi ezineprofayili ezijikelezayo ezijikelezayo kunye ne-linear motor drive.
Okokuqala, ngokungafaniyo nezinye iisistim zentshukumo zomgca, ezidla ngokusebenzisa i-aluminium extrusion okanye ipleyiti njengesiseko, inqanaba lomgca liqala ngesiseko esichanekileyo somhlaba.Izigaba ezenzelwe amanqanaba aphezulu okucaba, ukuthe tye, kunye nobungqongqo kaninzi zisebenzisa isiseko esenziwe ngentsimbi okanye igraniti, nangona i-aluminiyam isetyenziswa kwezinye iziyilo.Intsimbi kunye negranite nazo zinee-coefficients ezisezantsi zokwandiswa kwe-thermal kune-aluminiyam, ngoko ke zibonisa uzinzo olungcono lwe-dimensional kwiindawo ezinobushushu obugqithileyo okanye obahlukeneyo.
Inkqubo yesikhokelo somgca ikwanegalelo ekuthe tye kunye nokuthe tyaba kohambo, ngoko ke iindlela zesikhokelo ezikhethwayo kwiqonga lomda ziziporo ezineprofayili ezichanekileyo,izilayidi ezinqamlezileyo, okanyeiibheringi zomoya.Ezi nkqubo zesikhokelo zikwabonelela ngenkxaso engqongqo kakhulu yokunciphisa iimpazamo ze-angular, ezinokuthi zikhokelele kwiimpazamo zika-Abbé xa kukho i-offset phakathi kwemvelaphi yempazamo (isikhokelo) kunye nenqaku lomdla (indawo yesixhobo okanye indawo yomthwalo).
Ngelixa uninzi lweenkqubo zentshukumo ezichanekileyo zisebenzisa iindlela zokuqhuba ezichaneke kakhulu, izigaba zemigca zisebenzisa kakhulu itekhnoloji enye yeetekhnoloji ezimbini: isikrufu sebhola esichaneke kakhulu okanye isikrufu somgca.Iinjini zomgca zihlala zibonelela ngelona nqanaba liphezulu lokumisa ukuchaneka kunye nokuphinda-phinda, kuba zisusa ukuthotyelwa kunye nokubuyela umva kwi-drivetrain yomatshini kunye nokudibanisa phakathi kwedrive kunye nemoto.Kwimeko ekhethekileyo yemisebenzi yokubeka i-sub-micron,ii actuators piezookanyeiimotor zekhoyili yelizwingokwesiqhelo ziindlela zokuqhuba ezikhethwayo, ezichaneke kakhulu, neziphinda-phindayo.
Nangona igama elithi "inqanaba lomgca" lithetha inkqubo yentshukumo ye-axis enye, izigaba zinokudityaniswa ukwenza iinkqubo ezininzi ze-axis ezifana nezigaba ze-XY,izigaba ezicwangcisiweyo, kunye nezigaba gantry.
Esi sigaba se-gantry se-axis-axis sisebenzisa iibheringi zomoya kunye neenjini zomgca kwisiseko se-ceramic.
