Lapho abantu abaningi bezwa 'izingxenye zomshini ezinembayo', bafanekisela imodeli ye-CAD engenasici noma ingxenye ecwebezelayo kukhathalogi. Iqiniso liwukuthi messier. Ukunemba kweqiniso akukhona nje ngezinombolo eziseshidini elicacisiwe; kumayelana nendlela ingxenye ethile esinda ngayo lapho iqala ukuxhumana nomhlaba wangempela—ukucindezeleka, ukushisa, ukunyakaza okungapheli. Izitolo eziningi ziyakugeja lokho. Bajaha ukubekezelelana okuqinile ephepheni kodwa bakhohlwe ngesakhiwo sokusanhlamvu, ingcindezi eyinsalela evela kumishini, noma ukuthi ingxenye isebenzisana kanjani neseduze kwayo. Lelo gebe phakathi kokuhle nokusebenzayo yilapho kwenzeka khona umsebenzi wangempela.
Isisekelo: Iqala Nge-Ingot Elungile
Awukwazi ukwenza ukunemba komshini ube ukusakaza okubi. Ngibone amaphrojekthi amaningi kakhulu ehluleka ngoba othile uzame ukonga izindleko ekuqaleni kungenalutho. I-porosity, ubulukhuni obungaguquki-konke kubuya kuzokukhathaza ngesikhathi sokuqeda. Isiteji se-Foundry asixoxiswana. Inkampani efana ne-Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) ithola lokhu. Ngeminyaka engamashumi amathathu ekulingiseni nasekukhiqizeni imishini, indlela yabo ihlanganisiwe. Abagcini ngokuthengisa imishini; balawula inqubo kusukela ku-alloy encibilikisiwe kuye phambili. Ngoba ukunemba izingxenye mechanical ezinhlelweni ezifunayo, lokho kulawula okuqondile kuyinzuzo ethule. Kusho ukuthi umakhinikhi kanye nonjiniyela womsunguli bakhuluma ulimi olufanayo, izinkinga zokuxazulula izinkinga ezifana nokuncipha noma izinyembezi ezishisayo ngaphambi kokuba insimbi ishaye ngisho nombhede we-CNC.
Ukukhethwa kwezinto ezibonakalayo kungenye i-pitfall yakudala. Ukucacisa insimbi engagqwali cishe akunangqondo. Ingabe i-304 yokumelana nokugqwala okujwayelekile, noma i-316 yezindawo ze-chloride? Noma sikhuluma ngamamaki aqinisa imvula njengo-17-4PH, lapho umjikelezo wokwelapha ukushisa ubaluleke kakhulu njengomshini? Ngamavalvu okushisa okuphezulu noma izingxenye ze-turbine, ugxumela kuma-alloys asekelwe ku-nickel noma e-cobalt. Lezi isilwane esihlukile.
