Ukuqina kokushisa kwesisekelo se-granite kuthinta kanjani imiphumela yokulinganisa ye-CMM?

Ukusetshenziswa kwe-granite njengesisekelo se-Coordinate Measuring Machines (CMM) kuwumkhuba owamukelekayo embonini yokukhiqiza. Lokhu kungenxa yokuthi i-granite inokuqina okuhle kokushisa, okuyisici esibalulekile semiphumela yokulinganisa enembile ku-CMM. Kulesi sihloko, sizohlola ukuthi ukuzinza kokushisa kwesisekelo se-granite kuthinta kanjani imiphumela yokulinganisa ye-CMM.

Okokuqala, kubalulekile ukuqonda ukuthi kusho ukuthini ukuzinza kokushisa. Ukuzinza kokushisa kubhekisela ekhonweni lento yokumela izinguquko zokushisa ngaphandle kokushintsha okukhulu ezimpahleni zayo zomzimba nezamakhemikhali. Endabeni ye-CMM, ukuzinza kokushisa kuhlobene nekhono lesisekelo se-granite lokugcina izinga lokushisa elingaguquki naphezu kwezinguquko endaweni ezungezile.

Uma i-CMM isebenza, imishini ikhiqiza ukushisa, okungathinta imiphumela yokulinganisa. Lokhu kungenxa yokuthi ukwanda kokushisa kwenzeka lapho into ishiswa, okubangela izinguquko zobukhulu ezingaholela emaphutheni okulinganisa. Ngakho-ke, kubalulekile ukugcina izinga lokushisa eliyisisekelo elihlala njalo ukuqinisekisa imiphumela yokulinganisa ehambisanayo nenembile.

Ukusetshenziswa kwe-granite njengesisekelo se-CMM kunikeza izinzuzo eziningana. I-granite ine-coefficient ephansi yokwanda kokushisa, okusho ukuthi ayikhuli kakhulu uma ibhekene nokushintsha kwezinga lokushisa. Ine-conductivity ephezulu yokushisa ekhuthaza ukusatshalaliswa kokushisa okufanayo kuso sonke isisekelo. Ngaphezu kwalokho, i-porosity ephansi ye-granite kanye nesisindo sokushisa kusiza ukulawula ukushintsha kwezinga lokushisa futhi kunciphise imiphumela yokushintsha kwezinga lokushisa kwemvelo emiphumeleni yokulinganisa.

I-granite nayo iyinto eqinile kakhulu emelana nokuguquguquka futhi igcina isimo sayo ngisho noma ibhekene nokucindezeleka komshini. Le mfanelo ibalulekile ekuqinisekiseni indawo efanele yezingxenye zomshini, okungathinta kakhulu imiphumela yokulinganisa.

Ngamafuphi, ukuzinza kokushisa kwesisekelo se-granite kubalulekile ekunembeni nasekuqondeni kwezilinganiso ze-CMM. Ukusetshenziswa kwe-granite kunikeza isisekelo esizinzile nesihlala isikhathi eside esigcina izinga lokushisa elihlala njalo futhi simelana nezinguquko ngenxa yezici zangaphandle. Ngenxa yalokho, kuvumela umshini ukuthi ulethe imiphumela yokulinganisa enembile nengaguquguquki, uthuthukise ikhwalithi yomkhiqizo futhi unciphise izindleko zokukhiqiza.
