Uzinzo lwe-thermal kunye ne-coefficient yokwandisa okuphantsi kwe-granite inokuqinisekisa njani ukuchaneka komlinganiselo?

Ukusetyenziswa kwamacandelo e-granite kwi-Coordinate Measuring Machines (CMM) yinkqubo esekwe kakuhle kwishishini lokuvelisa.Igranite lilitye elenzeka ngokwendalo elinezinto ezibalaseleyo ezifana nokuzinza kwe-thermal, i-coefficient ephantsi yokwanda kwe-thermal, kunye nokuqina okuphezulu.Ezi propati zenza ukuba ibe yimathiriyeli efanelekileyo yokusetyenziswa ekwenzeni izixhobo zokulinganisa ezinovakalelo ezifana nee-CMM.Ezi propati ziqinisekisa ukuchaneka komlinganiselo ophezulu obalulekileyo kushishino lokuvelisa.

Ukuzinza kwe-Thermal yenye yezona zinto zibalulekileyo zegranite.Ii-CMM zizixhobo ezichanekileyo ekufuneka zizinzile nangona kukho ukuguquguquka kobushushu.Ukusetyenziswa kwegranite njengento yokwakha kuqinisekisa ukuba umatshini uhlala uzinzile, kungakhathaliseki ukuba utshintsho lweqondo lokushisa.I-coefficient yokwandiswa kwe-thermal ye-granite iphantsi, eqinisekisa ukuba naluphi na ukwanda kwe-thermal kuncinci, okuvumela ukuba imilinganiselo ihlale ihambelana nobubanzi obushushu bokusebenza.Le propati ibaluleke kakhulu ekuchanekeni kwemilinganiselo eyenziwa yi-CMM.

I-coefficient ephantsi yokwandiswa kwe-thermal ye-granite iqinisekisa ukuba imilinganiselo ethathwe yi-CMM ihlala ichanekile nangona kukho utshintsho lobushushu.Ukutshintsha kobushushu kunokuchaphazela ubungakanani kunye nokumila kwezinto ezilinganiswayo.Nangona kunjalo, ukusetyenziswa kwegranite njengento yokwakha ye-CMM iqinisekisa ukuba naluphi na utshintsho kwiqondo lokushisa aluchaphazeli ukuchaneka kwemilinganiselo.Le propati ibalulekile kwishishini lokuvelisa, apho ukuchaneka kubalulekile ekuqinisekiseni ukuba iimveliso ezigqityiweyo zihlangabezana neenkcukacha zabathengi.

Ukuqina okuphezulu yenye ipropathi ebalulekileyo eyenza igranite ibe yimathiriyeli efanelekileyo kwiiCMM.Amacandelo asetyenziswa kwii-CMM kufuneka aqine ukuxhasa into yokulinganisa, edla ngokuba yi-probe enovakalelo.Ukusetyenziswa kwegranite kuqinisekisa ukuba umatshini uhlala uqinile, unciphisa nayiphi na i-deformation ebangelwa ubunzima bento yokulinganisa.Le propati iqinisekisa ukuba iprobe yokulinganisa ihamba ngokuchanekileyo ecaleni kwee-asi ezintathu (x, y, kunye no-z) ezifunekayo ukuthatha imilinganiselo ngokuchanekileyo.

Ukusetyenziswa kwegranite ekwakhiweni kweCMM kwakhona kuqinisekisa ukuba umatshini uhlala uzinzile kwixesha elide.Igranite yimathiriyeli eshinyeneyo, eqinileyo engajikiyo, ingagobi, okanye igxumeke ngokuhamba kwexesha.Ezi zakhiwo ziqinisekisa ukuba umatshini uya kugcina ukuchaneka nokuchaneka kwawo kwiminyaka emininzi yokusebenza.Ukongeza, i-granite iyamelana nokunxiba kunye nokukrazula, okuthetha ukuba ifuna ukugcinwa okuncinci, ukunciphisa ixesha lokuphumla kunye nokwandisa ixesha elide lomatshini.

Ukuqukumbela, ukusetyenziswa kwegranite kulwakhiwo lweCMM kubalulekile ekuqinisekiseni ukuchaneka komlinganiselo ophezulu kwishishini lokuvelisa.Iimpawu ezikhethekileyo zegranite, ezifana nokuzinza kwe-thermal, i-coefficient ephantsi yokwandiswa kwe-thermal, kunye nokuqina okuphezulu, qinisekisa ukuba umatshini uhlala uchanekile nangona kukho ukuguquka kweqondo lokushisa.Ukongeza, ukuqina kwegranite kunye nokuxhathisa ukunxiba kuqinisekisa ukuba umatshini ugcina ukuchaneka kwawo kwiminyaka emininzi yokusebenza.Ngokubanzi, ukusetyenziswa kwegranite kwiiCMM lutyalo-mali olulumkileyo ekuqinisekiseni imveliso kunye nomgangatho kwishishini lemveliso.
