Ukunemba kwama-blade enjini ye-aero kuhlobene nokusebenza kahle komshini, futhi ukulinganiswa kwe-contour okunezinhlangothi ezintathu ezingeni lika-0.1μm sekuyinto edingekayo ekukhiqizeni. Amapulatifomu endabuko kunzima ukuhlangabezana nezindinganiso. Amapulatifomu e-granite, anezinzuzo zawo ezintathu ezinkulu, anikeza ukwesekwa okuthembekile kokutholwa okunembile.
Ukuqina kokushisa kwakha isisekelo esinembile. I-coefficient yokwanda kokushisa kwe-granite ingaphansi kuka-(4-8) ×10⁻⁶/℃ kuphela, okungaphansi kuka-60% kunokwezinsimbi. Ngaphansi kokushintshashintsha kwezinga lokushisa okungu-±1℃, ushintsho losayizi wepulatifomu enobude obuyimitha eli-1 lungaphansi kuka-0.008μm, okungahlinzeka ngendawo yokubhekisela eqhubekayo yemishini efana nama-laser interferometers kanye nemishini yokulinganisa enama-coordinate amathathu, kugwema ukuqongelela kwamaphutha okulinganisa abangelwa ukuguqulwa kokushisa. Okwamanje, ubuningi bayo bufinyelela ku-2.6-2.8g/cm³, amandla ayo okucindezela adlula i-200MPa, ayigugi, futhi iqinisekisa ukuthi ukunemba akushintshi ngokusetshenziswa kwesikhathi eside.
Ukumelana nokudlidliza okuvelele kanye nokuhlukaniswa kokuphazamiseka kwemvelo. Indawo yokusebenzela yezindiza iyadlidliza njalo. Isakhiwo sekristalu esiyingqayizivele segranite senza isilinganiso sayo sokudambisa sifinyelele ku-0.05-0.1, okuphindwe ka-5-10 kunesezinsimbi. Singanciphisa amandla okudlidliza angaphezu kuka-90% ngemizuzwana engu-0.3. Uma kuthathwa isilinganiso nge-laser tracker njengesibonelo, uma sihlanganiswa nepulatifomu yegranite, i-laser beam offset ingalawulwa ngaphakathi kuka-±0.02μm, okuthuthukisa kakhulu ukunemba kokulinganisa kwamaphutha ephrofayili ye-blade.
Ukuhlanganiswa kobuciko obunembile kanye nobuhlakani kuthuthukisa ukusebenza kahle. Ngemva kokucubungula okunembile kakhulu njengokupholisha kwe-magnetorheological, ukuba yisicaba kwepulatifomu ye-granite kufinyelela ku-±0.1μm/m, kanti ubulukhuni bomphezulu i-Ra bungu-≤0.02μm. Ngemva kokuhlanganiswa nama-nanoscale grating rulers kanye nama-algorithms e-AI, ukunemba kokulinganisa kwe-single-point kufinyelela ku-0.05μm, iphutha lilonke lincishiswa libe yi-±0.1μm, ukusebenza kahle kokuthola kukhushulwa ngo-30%, kanti izinga lokuthola amaphutha lifinyelela ku-99.9%.
Amapulatifomu e-granite, ngokusebenza kwawo okuzinzile nokuthembekile, avikela ukulinganiswa okunembile kwama-blade enjini ye-aero, akhuthaza ukuthuthukiswa kokunemba kokukhiqiza izindiza, futhi asize imboni ukuthi ifinyelele amazinga amasha.
