Ukuzinza kwe-thermal kanye ne-coefficient ephansi yokunwetshwa kwegwadle kungaqinisekisa kanjani ukunemba kokulinganisa?

Ukusetshenziswa kwezingxenye ze-granite ku-Coordinate Measuring Machines (CMM) kuwumkhuba osungulwe kahle embonini yokukhiqiza.I-Granite iyidwala elenzeka ngokwemvelo elinezinto ezinhle kakhulu ezifana nokuzinza kwe-thermal, i-coefficient ephansi yokwanda okushisayo, nokuqina okuphezulu.Lezi zakhiwo ziyenza ibe into efanelekile ukuthi isetshenziswe ekwenzeni izinsimbi zokulinganisa ezizwelayo njengama-CMM.Lezi zakhiwo ziqinisekisa ukunemba kokulinganisa okuphezulu okubalulekile embonini yokukhiqiza.

Ukuzinza kwe-thermal kungenye yezinto ezibaluleke kakhulu ze-granite.Ama-CMM angamathuluzi anembayo okufanele azinze ngisho nalapho kukhona ukushintshashintsha kwezinga lokushisa.Ukusetshenziswa kwe-granite njengento yokwakha kuqinisekisa ukuthi umshini uhlala uzinzile, kungakhathaliseki ukuthi izinga lokushisa liyashintsha.I-coefficient yokunwetshwa okushisayo kwe-granite iphansi, okuqinisekisa ukuthi noma yikuphi ukunwetshwa kokushisa kuncane, okuvumela izilinganiso ukuthi zihlale zifana phezu kwebanga elibanzi lokushisa lokusebenza.Lesi sakhiwo sibalulekile ekunembeni kwezilinganiso ezenziwe ama-CMM.

I-coefficient ephansi yokunwetshwa okushisayo kwegwadle iqinisekisa ukuthi izilinganiso ezithathwe ama-CMM zihlala zinembile ngisho noma kukhona izinguquko zezinga lokushisa.Ukushintsha kwezinga lokushisa kungathinta usayizi nokuma kwezinto ezilinganiswayo.Kodwa-ke, ukusetshenziswa kwe-granite njengento yokwakha yama-CMM kuqinisekisa ukuthi noma yikuphi ukuguquka kwezinga lokushisa akuthinti ukunemba kwezilinganiso.Lesi sakhiwo sibalulekile embonini yokukhiqiza, lapho ukunemba kubalulekile ekuqinisekiseni ukuthi imikhiqizo eqediwe iyahlangabezana nezidingo zamakhasimende.

Ukuqina okuphezulu kungenye impahla ebalulekile eyenza i-granite ibe yinto efanelekile yama-CMM.Izingxenye ezisetshenziswa kuma-CMM kufanele ziqine ukuze zisekele isici sokulinganisa, ngokuvamile esiwuphenyo olubucayi.Ukusetshenziswa kwe-granite kuqinisekisa ukuthi umshini uhlala uqinile, unciphisa noma yikuphi ukuguqulwa okubangelwa isisindo sesici sokulinganisa.Lesi sakhiwo siqinisekisa ukuthi i-probe yokulinganisa ihamba ngokunembile kuma-eksisi amathathu (x, y, kanye no-z) adingekayo ukuze kuthathwe izilinganiso ngokunembile.

Ukusetshenziswa kwe-granite ekwakhiweni kwe-CMM nakho kuqinisekisa ukuthi umshini uhlala uzinzile esikhathini eside.I-Granite iyimpahla eminyene, eqinile engasonti, ingagobi, noma igoqe ngokuhamba kwesikhathi.Lezi zakhiwo ziqinisekisa ukuthi umshini uzogcina ukunemba nokunemba kwawo phakathi neminyaka eminingi yokusebenza.Ukwengeza, i-granite imelana nokuguga, okusho ukuthi idinga ukulungiswa okuncane, ukunciphisa isikhathi sokuphumula nokwandisa isikhathi eside somshini.

Sengiphetha, ukusetshenziswa kwe-granite ekwakhiweni kwe-CMM kubalulekile ekuqinisekiseni ukunemba kokulinganisa okuphezulu embonini yokukhiqiza.Izakhiwo eziyingqayizivele ze-granite, njengokuzinza kokushisa, i-coefficient ephansi yokwandisa ukushisa, nokuqina okuphezulu, kuqinisekisa ukuthi umshini uhlala unembile ngisho nalapho kukhona ukushintshashintsha kwezinga lokushisa.Ukwengeza, ukuqina kwegwadle kanye nokumelana nokugqokwa kuqinisekisa ukuthi umshini ugcina ukunemba kwawo phakathi neminyaka eminingi yokusebenza.Sekukonke, ukusetshenziswa kwe-granite kuma-CMM kuwukutshalwa kwezimali okuhlakaniphile ekuqinisekiseni ukukhiqiza kanye nekhwalithi embonini yokukhiqiza.
