Ukusetshenziswa kwegwadle njengesisekelo se-Coordinate Measuring Machines (CMM) kuwumkhuba owamukelwe kahle embonini yokukhiqiza.Lokhu kungenxa yokuthi igwadle linozinzo oluhle kakhulu lwe-thermal, okuyisici esibalulekile ukuze uthole imiphumela yokulinganisa enembile ku-CMM.Kulesi sihloko, sizohlola ukuthi ukuzinza okushisayo kwesisekelo se-granite kuyithinta kanjani imiphumela yokulinganisa ye-CMM.
Okokuqala, kubalulekile ukuqonda ukuthi kusho ukuthini ukuzinza kwe-thermal.Ukuzinza kwe-thermal kusho ikhono lempahla ukumelana noshintsho olushisayo ngaphandle koshintsho olubalulekile ezimpahleni zayo ezibonakalayo namakhemikhali.Endabeni ye-CMM, ukuzinza kwe-thermal kuhlobene nekhono lesisekelo se-granite ukugcina izinga lokushisa eliqhubekayo naphezu kwezinguquko endaweni ezungezile.
Uma i-CMM isebenza, okokusebenza kukhiqiza ukushisa, okungathinta imiphumela yokulinganisa.Lokhu kungenxa yokuthi ukunwetshwa kwe-thermal kwenzeka lapho okokusebenza kushisa, okubangela izinguquko zobukhulu ezingaholela kumaphutha okulinganisa.Ngakho-ke, kubalulekile ukugcina izinga lokushisa eliyisisekelo elingaguquki ukuze uqinisekise imiphumela yokulinganisa engaguquki nenembile.
Ukusetshenziswa kwe-granite njengesisekelo se-CMM kunikeza izinzuzo ezimbalwa.I-Granite ine-coefficient ephansi yokunwetshwa kokushisa, okusho ukuthi ayikhuli kakhulu uma ingaphansi kokushintsha kwezinga lokushisa.Ine-conductivity ephezulu ye-thermal ekhuthaza ukusatshalaliswa kwezinga lokushisa okufanayo kusisekelo sonkana.Ngaphezu kwalokho, i-porosity ephansi ye-granite nesisindo sokushisa kusiza ukulawula ukuhlukahluka kwezinga lokushisa futhi kunciphise imiphumela yoshintsho lwezinga lokushisa kwemvelo emiphumeleni yokulinganisa.
I-Granite iphinde ibe yinto ezinzile kakhulu ephikisana ne-deformation futhi igcina isimo sayo ngisho nalapho ibhekene nokucindezeleka kwemishini.Lesi sakhiwo sibalulekile ekuqinisekiseni ukuma okunembile kwezingxenye zemishini zemishini, okungaba nomthelela omkhulu emiphumeleni yokulinganisa.
Kafushane, ukuzinza okushisayo kwesisekelo se-granite kubalulekile ekunembeni nokunemba kwezilinganiso ze-CMM.Ukusetshenziswa kwe-granite kunikeza isisekelo esizinzile nesiqinile esigcina izinga lokushisa elihlala njalo futhi simelana nezinguquko ngenxa yezici zangaphandle.Ngenxa yalokho, ivumela umshini ukuthi ulethe imiphumela yokulinganisa enembile futhi engaguquki, uthuthukise ikhwalithi yomkhiqizo futhi unciphise izindleko zokukhiqiza.
