1. Ukulungiselela ngaphambi kovavanyo
Ngaphambi kokuba sifumanise ngokuchanekileyo izinto ezichanekileyo zegranite, kufuneka siqale siqinisekise uzinzo kunye nokufaneleka kwendawo yokufumanisa. Indawo yokuvavanya kufuneka ilawulwe kubushushu obungaguqukiyo kunye nokufuma ukuze kuncitshiswe impembelelo yezinto ezingqongileyo kwiziphumo zovavanyo. Kwangaxeshanye, izixhobo kunye nezixhobo ezifunekayo ukuze kufunyanwe, ezinje ngee-calipers ze-vernier, izalathisi ze-dial, oomatshini bokulinganisa abalungelelanisiweyo, njl.njl., kufuneka zilinganiswe ukuqinisekisa ukuba ukuchaneka kwazo kuyahlangabezana neemfuno zokufumanisa.
2. Ukuhlolwa kwenkangeleko
Ukuhlolwa kwenkangeleko linyathelo lokuqala lokufumanisa, ikakhulu ukujonga ukuba umphezulu uthe tyaba kangakanani, ukufana kombala, imingxunya kunye nemikrwelo yezixhobo ezichanekileyo zegranite. Umgangatho uwonke wecandelo ungagwetywa kuqala ngokubona okanye ngoncedo lwezixhobo ezincedisayo ezifana ne-microscope, ebeka isiseko sovavanyo olulandelayo.
3. Uvavanyo lwepropathi ebonakalayo
Uvavanyo lweempawu ezibonakalayo linyathelo elibalulekileyo ekufumaneni ukuchaneka kwezinto zegranite. Izinto eziphambili zovavanyo ziquka uxinano, ukufunxwa kwamanzi, i-thermal expansion coefficient, njl. Ezi mpawu zomzimba zichaphazela ngokuthe ngqo uzinzo kunye nokuchaneka kwecandelo. Umzekelo, igranite efunxwa amanzi aphantsi kunye ne-thermal expansion coefficient ephezulu inokugcina uzinzo oluhle phantsi kweemeko ezahlukeneyo zokusingqongileyo.
Okwesine, umlinganiselo wobungakanani bejometri
Ukulinganisa ubukhulu bejometri linyathelo elibalulekileyo lokufumanisa ukuchaneka kwezinto zegranite. Ubukhulu obuphambili, iimilo kunye nokuchaneka kwendawo yezinto zilinganiswa ngokuchanekileyo ngokusebenzisa izixhobo zokulinganisa ezichanekileyo ezifana ne-CMM. Ngexesha lenkqubo yokulinganisa, kuyimfuneko ukulandela ngokungqongqo iinkqubo zokulinganisa ukuqinisekisa ukuchaneka nokuthembeka kweziphumo zokulinganisa. Kwangaxeshanye, kuyimfuneko ukwenza uhlalutyo lwezibalo kwidatha yokulinganisa ukuvavanya ukuba ukuchaneka kwento kuyahlangabezana neemfuno zoyilo.
5. Uvavanyo lokusebenza olusebenzayo
Kwizixhobo zokuchaneka kwegranite ngeenjongo ezithile, uvavanyo lokusebenza olusebenzayo nalo luyafuneka. Umzekelo, izixhobo zegranite ezisetyenziswa kwizixhobo zokulinganisa kufuneka zivavanywe ukuze kuqinisekiswe ukuba zizinzile na ukuze kuhlolwe indlela ukuchaneka kwazo okutshintsha ngayo ngexesha lokusetyenziswa ixesha elide. Ukongeza, iimvavanyo zokungcangcazela, iimvavanyo zempembelelo, njl.njl. nazo ziyafuneka ukuze kuhlolwe ukuzinza nokuqina kwezixhobo phantsi kweemeko ezahlukeneyo zokusebenza.
6. Uhlalutyo lweziphumo kunye nomgwebo
Ngokweziphumo zovavanyo, ukuchaneka kweenxalenye zegranite ngokuchanekileyo kuyahlalutywa kwaye kugwetywe ngokupheleleyo. Kwiinxalenye ezingazifezekisi iimfuno, kuyimfuneko ukufumanisa izizathu kunye nokuthatha amanyathelo okuphucula afanelekileyo. Kwangaxeshanye, kuyimfuneko ukuseka irekhodi epheleleyo yovavanyo kunye nefayile yokubonelela ngenkxaso yedatha kunye nesalathiso semveliso nokusetyenziswa okulandelayo.
