Uyini umphumela we-coefficient yokwandisa okushisayo kwesisekelo se-granite emshinini wokulinganisa?

I-coefficient yokwandisa okushisayo kwesisekelo se-granite sinomthelela obalulekile emshinini wokulinganisa.Isisekelo se-granite sivame ukusetshenziswa njengesisekelo somshini wokulinganisa ohlanganisa ezintathu (CMM) ngenxa yokuqina kwawo okuhle kakhulu, ukuzinza, nokuqina.I-granite ine-coefficient ephansi yokunwetshwa kwe-thermal, okusho ukuthi inoshintsho oluncane lwe-dimensional ngaphansi kwamazinga okushisa ahlukahlukene.Nokho, ngisho nokunwetshwa okuphansi kokushisa, i-coefficient yesisekelo se-granite isengathinta ukunemba nokunemba komshini wokulinganisa.

Ukunwetshwa kwe-thermal kuyisimo lapho izinto zikhula noma zincipha njengoba izinga lokushisa lishintsha.Uma kuvezwe amazinga okushisa ahlukene, isisekelo segwadle singanwebeka noma sinciphe, okuholela ekushintsheni kobukhulu obungabangela izinkinga ku-CMM.Lapho izinga lokushisa likhuphuka, isisekelo se-granite sizokhula, okubangela ukuthi izikali eziqondile nezinye izingxenye zomshini zishintshe ngokuhlobene nomsebenzi.Lokhu kungaholela emaphutheni okulinganisa futhi kuthinte ukunemba kwezilinganiso ezitholiwe.Ngokuphambene, uma izinga lokushisa lincipha, isisekelo se-granite sizoncipha, okungase kubangele izinkinga ezifanayo.

Ngaphezu kwalokho, izinga lokunwetshwa okushisayo kwesisekelo se-granite lizoncika ekugqimeni kwayo, usayizi, nendawo.Isibonelo, isisekelo se-granite esikhulu nesiwugqinsi sizoba ne-coefficient ephansi yokunwetshwa okushisayo futhi sibhekane nezinguquko zobukhulu obuncane kunesisekelo esincane nesincane segwadle.Ukwengeza, indawo yomshini wokulinganisa ingathinta izinga lokushisa lendawo ezungezile, okungabangela ukunwetshwa kokushisa kwehluke ezindaweni eziningi.

Ukuze kubhekwane nalolu daba, abakhiqizi be-CMM baklama imishini yokulinganisa ukuze banxephezele ukunwetshwa kokushisa.Ama-CMM athuthukile eza nesistimu yokulawula izinga lokushisa esebenzayo egcina isisekelo segwadle ezingeni lokushisa elingashintshi.Ngale ndlela, ukuguqulwa okubangelwa izinga lokushisa kwesisekelo se-granite kuyancishiswa, ngaleyo ndlela kuthuthukiswe ukunemba nokunemba kwezilinganiso ezitholiwe.

Ekuphetheni, i-coefficient yokwandisa okushisayo kwesisekelo se-granite iyisici esibalulekile ekusebenzeni okuphelele komshini wokulinganisa we-3-coordinate.Kungathinta ukunemba, ukunemba, nokuzinza kwezilinganiso ezitholiwe.Ngakho-ke, kubalulekile ukuqonda izici ezishisayo zesisekelo se-granite futhi sisebenzise izinyathelo ezibhekana nokwanda kokushisa ngesikhathi sokuklama nokusebenza kwe-CMM.Ngokwenza kanjalo, singaqinisekisa ukuthi i-CMM iletha imiphumela yokulinganisa ethembekile nephindaphindwayo ehlangabezana nokunemba nokunemba okufunayo.
