Ukukhethwa kwezinto kubonakalisa ikamva lamanqanaba achanekileyo

Kwicandelo lokuvelisa ngokuchanekileyo elitshintsha ngokukhawuleza namhlanje, ukukhethwa kwezinto zokwakha zezigaba ezithe tye kunye nezixhobo ze-metrology kuye kwavela njengento ebalulekileyo echaphazela ukusebenza, ukuthembeka, kunye nokuchaneka kokulinganisa. Abahlalutyi abaphambili kushishino bagxininisa ukuba iziseko zegranite, zeseramikhi, nezentsimbi ngoku ziphantsi koqwalaselo olunzulu njengoko iinjineli kunye nabaphathi belebhu befuna izisombululo ezifanelekileyo zokudambisa ukungcangcazela, ukuzinza kobushushu, kunye nokuthembeka kwexesha elide.

Iindlela zamva nje zibonisa ukuba i-granite ithandwa kakhulu kwiinkqubo zokulinganisa ezichanekileyo, ngelixa ii-ceramics zifumana ingqalelo kwiindawo ezikhethekileyo zelebhu. Intsimbi, nangona iqhele ukuba yinxalenye yoomatshini bemizi-mveliso, iphinda ihlolwe ngenxa yeemfuno zanamhlanje zokuchaneka.

I-Granite Igcina Indawo Eqinileyo Kwizicelo zeMetrology

Iingcali kwizixhobo ze-metrology zixela ukuba i-granite isaqhubeka nokuba yinto ekhethwayo kwiiplati zomphezulu kunye nezigaba zokuchaneka ngenxa yeempawu zayo zendalo zokungcangcazela, ukwanda kobushushu obuphantsi, kunye nokuqina. Ngokwezifundo zakutshanje zoshishino, i-granite emnyama enoxinano oluphezulu isathandwa kakhulu kwiimashini zokulinganisa ezilungelelanisiweyo (ii-CMM), iinkqubo zokuhlola ezibonakalayo, kunye namaqonga okuhamba ngomgca azenzekelayo.

“Ubuchule beGranite bokufunxa ukungcangcazela ngelixa igcina ithambile ixesha elide buyenza ibaluleke kakhulu kwiindawo ezichanekileyo,” utshilo unjineli ophezulu kwilebhu ephambili yemetrology yaseYurophu. “Uzinzo lwayo luqinisekisa ukuba imilinganiselo ihlala ifana, nokuba isetyenziswa rhoqo.”

Iintlobo zeGranite kwizicelo zokuchaneka

Abantu abasebenzisa le mveliso bagxininisa ukuba ayizizo zonke iigranite ezifanelekileyo ngokulinganayo kwizigaba zokuchaneka. Izinto ezibalulekileyo ziquka:

• Ubuninzi kunye nokuhambelana, okuchaphazela ukuxinana kunye nokuhambelana koomatshini

• Ii-coefficients zokwandiswa kobushushu, ezichaphazela ukuchaneka phantsi kwamaqondo obushushu ahlukeneyo

• Ulwakhiwo lweenkozo, oluchaphazela ukugqitywa komphezulu kunye nokumelana nokuguguleka

• Iindlela zokucubungula, kubandakanya ukunciphisa uxinzelelo kunye nokudibanisa ngokuchanekileyo

Kuthiwa abavelisi abagxile kwizinto zegranite ezichanekileyo basebenzisana ngokusondeleyo nabakhi bezixhobo ukuphucula ukukhethwa kwezinto ezisetyenziswayo kwizicelo ezithile zemetrology.

Ingxoxo phakathi kweGranite neCeramic: Ubunjineli

Izixhobo zeseramikhi ziye zavela njengeendlela ezifanelekileyo kwiindawo ezichanekileyo zelebhu ezilawulwayo. Ngenxa yobunzima obuphezulu kunye neempawu zokwandiswa kobushushu ezilungiselelwe wena, izigaba zeseramikhi ziyagqwesa kwiinkqubo ezikhaphukhaphu nezikhawulezayo.

Nangona kunjalo, izimvo zoshishino zibonisa ukuba iiseramikhi ngokubanzi zibonelela ngokunciphisa ukungcangcazela okuncinci kwaye zibuthathaka ngakumbi kunegranite, nto leyo ethintela ukunyamezela kwazo ukusebenza kwiindawo zoshishino. Abahlalutyi baqaphela ukuba nangona iiseramikhi zifanelekile kwiindawo ezilawulwa kakhulu, igranite igcina ububanzi bokusetyenziswa kwayo ngenxa yokuqina kwayo kunye nokulungiswa kwayo.

I-Granite vs Steel: Iingqwalasela ze-Linear Motion

Iziseko zentsimbi, ezazithandwa kakhulu koomatshini bemizi-mveliso, ziphantsi kovavanyo olutsha ukuze zifumane izigaba ezichanekileyo zomgca. Intsimbi inika ukuqina kunye nokulula komatshini kodwa ibonisa ukwanda okuphezulu kobushushu kunye nokunciphisa ukungcangcazela xa kuthelekiswa negranite. Iingcali zicebisa ukuba kwizicelo ezifuna ukuphindaphindwa kwinqanaba le-micrometer, iziseko zentsimbi zifuna ulawulo olongezelelweyo lokusingqongileyo okanye ukwahlulwa kokungcangcazela ukuze kufezekiswe ukusebenza okufana negranite.

Iindlela Zoshishino Neendlela Ezivelayo

Ngokweengxelo zamva nje ezivela kwiilabhoratri zaseMntla Melika naseYurophu:

• Iziseko zegranite ziya kuhlanganiswa ngakumbi kwiinkqubo zokuhlola ezenzekelayo, ii-CMM, kunye namaqonga optical

• Uyilo lwe-hybrid oludibanisa iziseko ze-granite kunye nezinto ezihambayo zentsimbi okanye i-aluminium ziya ziqheleka

• Iiceramics ziya kwamkelwa kwiindawo zokusebenzela apho ubunzima obuphantsi kunye nokuzinza kobushushu kubaluleke kakhulu

Ezi ndlela zigxininisa ukubaluleka okuqhubekayo kokukhethwa kwezinto kubunjineli bokuchaneka, zigxininisa ukuba izinto ezisisiseko azisezozinto ezixhasayo kodwa zinegalelo elisebenzayo ekuchanekeni kokulinganisa.

Ingxelo yeengcali

“Ukukhetha izinto ezifanelekileyo kwinqanaba lokuchaneka akusekho lukhetho lobunjineli olulula—sisigqibo esibalulekileyo esichaphazela ukulinganiswa kwexesha elide, ukuthembeka kwenkqubo, kunye nokusebenza kakuhle,” utshilo umphathi ophezulu we-R&D kumvelisi omkhulu wezixhobo ze-metrology. “I-Granite isaqhubeka iphambili kuninzi lwezicelo zoshishino kunye nokuchaneka okuphezulu, kodwa i-ceramics kunye neenkqubo ze-hybrid zifumana indawo yazo kwiimarike ezikhethekileyo.”

Isiphelo

Ingxoxo eqhubekayo phakathi kwegranite, iceramic, kunye nentsimbi igxininisa umkhwa obanzi kubunjineli bokuchaneka: izixhobo zibaluleke kakhulu njengezinzwa okanye isoftware ekumiseleni ukusebenza kwenkqubo. Uzinzo lwexesha elide lwegranite, ukudambisa ukungcangcazela, kunye nokuqina kwayo kuyaqhubeka nokuyenza ibe lukhetho olukhethwayo kwizigaba ezichanekileyo, ngelixa iceramics zibonelela ngezisombululo ezikhethekileyo kwiindawo ezilawulwayo. Intsimbi, nangona ibalulekile ngokwembali, ngoku ifuna ukuqwalaselwa ngononophelo kuyilo ukuze ihambelane namanqanaba okusebenza kweenkqubo ezisekelwe kwigranite.

Abahlalutyi bemizi-mveliso baqikelela ukuba njengoko ukunyamezelana kuqhubeka kuqina kwimizi-mveliso ye-metrology, i-semiconductor, kunye ne-optical, ukukhethwa kwezinto ezinolwazi kuya kuhlala kuyinto ebalulekileyo ekuqinisekiseni ukuthembeka kokulinganisa kunye nokusebenza kakuhle.
