Kwiminyaka yakutshanje, imfuno yezixhobo ze-titanium ibone ukwanda okubonakalayo kuwo wonke amashishini ahlukeneyo, afana ne-aerospace, izithuthi, kunye nezonyango. Njengoko izicelo zale mathiriyeli imangalisayo ziqhubeka zisanda, abavelisi baqhubeka bephonononga iindlela ezintsha zokuphucula ngakumbi ukusebenza kakuhle kunye nokuchaneka kwe.ukwenziwa kwe-titanium. Inkqubela phambili yamva nje kweli candelo kukuphunyezwa kobuchule bomatshini beCNC obukwinqanaba eliphezulu, ngakumbi ekusetyenzweni kwe-titanium yeBakala 5 (Gr5). I-Titanium Gr5, ekwabizwa ngokuba yi-Ti-6Al-4V, sisixhobo se-titanium esisetyenziswa ngokubanzi ngenxa yomlinganiselo wayo okhethekileyo wamandla ukuya kubunzima, ukumelana nokudleka, kunye nokusebenza kobushushu obuphezulu. Nangona kunjalo, ukwenza le ngxubevange ngumsebenzi onzima kakhulu, ngakumbi ngenxa yokuqhuba kwayo okuphantsi kwe-thermal, imodyuli ephezulu yokuqina, kunye nokuqina kwempahla.
Iindlela zemveli zokwenza oomatshini zihlala zikhokelela ekunxityweni kwezixhobo ezigqithisileyo, umphezulu ongemhle umphezulu, kunye nobomi besixhobo obunyiniweyo, okukhokelela kumaxabiso aphezulu emveliso kunye namaxesha amade okukhokela. Ukoyisa le miceli mngeni, abavelisi baya beguqukela kubuchule bomatshini be-CNC obuphambili bokwenza inkqubo yokuvelisa.titanium Gr5amacandelo. Obu buchule bubandakanya i-high-speed machining, i-adaptive machining, kunye ne-cryogenic machining, phakathi kwabanye. I-high-speed machining (HSM) ibandakanya ukusetyenziswa kwezixhobo zokusika ezikhethekileyo, iiparitha zokusika eziphuculweyo, kunye nesantya esiphezulu se-spindle ukunyusa amazinga okususwa kwezinto ngelixa ugcina ukugqiba kunye nokuchaneka. Ngokusebenzisa i-HSM, abavelisi banokunciphisa ixesha lokuhlala kweso sixhobo, ukunciphisa ukushisa kunye nokugqoka isixhobo ngexesha lenkqubo yokusika, okubangela ukuphuculwa kwemveliso kunye nokunciphisa iindleko zomatshini. I-Adaptive machining, kwelinye icala, isebenzisa abenzi boluvo abaphambili kunye neenkqubo zokubeka iliso ukuqokelela idatha yexesha langempela ngexesha lomsebenzi womatshini.
Le datha ke icutshungulwa ngama-algorithms aphucukileyo ukwenza uhlengahlengiso ngexesha langempela, ukulungelelanisa iiparitha zokusika ezisekelwe kwiimpawu ezithile ze-workpiece. Ezo nkqubo zolawulo eziguquguqukayo zenza ukuba abavelisi bafezekise ukuchaneka okuphezulu, ukuphucula ukugqitywa komphezulu, kunye nokwandisa ubomi besixhobo, ekugqibeleni baphucula ukusebenza kakuhle kwenkqubo. Olunye ubugcisa obuvelayo kumatshini we-titanium Gr5 yi-cryogenic machining. Ngokuzisa i-nitrogen ye-liquid okanye ezinye izinto ze-cryogenic kwindawo ye-machining, indawo yokusika ipholile ngokukhawuleza, enciphisa ngokufanelekileyo ukushisa okwenziwa ngexesha lomatshini. Esi siphumo sokupholisa asincedi nje ukwandisa ubomi besixhobo kodwa sikwaphucula ulawulo lwetshiphu, ukunciphisa umngcipheko wokwakheka komphetho owakhelwe phezulu kunye nokwenza abavelisi bafezekise umphezulu ogqwesileyo. Ukuphunyezwa kweubuchule bomatshini be-CNCkwi-titanium Gr5 ineempembelelo ezibalulekileyo kumashishini ahlukeneyo.
Kwicandelo le-aerospace, ukusetyenziswa kwe-speed-speed machining kunye ne-adaptive machining kunokukhokelela ekuphuculeni ukusebenza kakuhle kwamafutha ngokunciphisa ubunzima bezixhobo zeenqwelo-moya, ngelixa livumela ukuyilwa kwezakhiwo ezinzima kunye nezilula. Kumzi-mveliso weemoto, obu buchule buphucukileyo bunokuphucula ukusebenza kunye nokusebenza kakuhle kwamafutha ezithuthi ngokuvumela ukuveliswa kwezinto ezikhaphukhaphu nezomelele ngakumbi zenjini. Ngapha koko, kwicandelo lezonyango, abavelisi banokusebenzisa obu buchule bokwenza izinto ezintsonkothileyo kunyeukufakelwa kwe-titanium echanekileyo, ukuqinisekisa iziphumo ezingcono zesigulane kunye namaxesha okubuyisela ngokukhawuleza. Ngelixa obu buchule buphucukileyo bubonelela ngezinto ezininzi ezilungileyo, ukuphunyezwa kwazo kufuna abasebenzi abanezakhono eziphezulu, oomatshini abaphucukileyo, kunye neenkqubo ezomeleleyo zolawulo lomgangatho. Njengoko imfuno yamacandelo e-titanium Gr5 iqhubeka nokukhula, abavelisi kufuneka batyale imali kwizixhobo eziyimfuneko kunye noqeqesho ukuze basebenzise ngokupheleleyo amandla obuchwephesha bomatshini be-CNC.
Ukuqukumbela, ukudityaniswa kobuchule bomatshini be-CNC obuphucukileyo butshintshe ukwenziwa kwezinto ze-titanium Gr5. Ngomatshini onesantya esiphezulu, umatshini oguquguqukayo, kunye noomatshini be-cryogenic, abavelisi banokoyisa imiceli mngeni yendalo enxulumene nokwenza le mathiriyeli inzima. Obu buchule bokusika abuqhubeli nje ukuqhubela phambili kumashishini ahlukeneyo kodwa lukwanegalelo kuphuhliso lweemveliso ezizinzileyo nezisebenzayo.
