I-CNC (ikhompyutha elawulwa ngamanani) oomatshini basetyenziselwa ukudala iindawo ezijikiweyo ezinomgangatho ophezulu kakhulu wokuchaneka.Aba matshini balungelelaniswe ukuba balandele uluhlu lwemiyalelo ebaxelela indlela yokusika nokulungisa izinto.Le nkqubo iqinisekisa ukuba inxalenye nganye ifana ncakasana naleyo iphambi kwayo, eyimfuneko kwizicelo zobunjineli ezichanekileyo.
Ekujikeni kwe-CNC, i-workpiece ijikeleza malunga nesixhobo sokusika ukwenza iindawo ezichanekileyo.I-CNC-turned parts ingasetyenziswa kwinani lamashishini, ukusuka kwi-automotive ukuya kwi-aerospace.Kwiimeko ezininzi, zisetyenziselwa ukwenza amacandelo amancinci kakhulu okanye athambileyo ukuba adalwe zezinye iindlela zokuvelisa.Ngombulelo kwinqanaba eliphezulu lokuchaneka kunye nokuphindaphinda, amacandelo aguqulelwe kwi-CNC ahlala esetyenziswa kwizicelo ezibalulekileyo apho ukungaphumeleli akukhethi.
Xa kuziwa kula macandelo, ukuqwalaselwa koyilo kubalulekile kwimpumelelo yemveliso egqityiweyo.Eli nqaku liza kuxubusha ezintlanu zezona ngqwalasela zibalulekileyo zoyilo lwe-CNC-turned parts.
1) Ukukhethwa kwezinto eziphathekayo
Izinto ozisebenzisayo kwi-CNC-turned part inokuchaphazela kakhulu ukuyila ngokubanzi.Umzekelo, iintsimbi ezifana ne-aluminiyam kunye nobhedu zithambile kwaye zine-ductile, zenza kube lula ukwenza umatshini.Nangona kunjalo, zikwathandeka ukuba zingomelelanga kwaye zomelele kunezixhobo ezilukhuni njengentsimbi okanye i-titanium.Ukuze wenze ukhetho olungcono kakhulu, kubalulekile ukuqwalasela isicelo kunye neempawu ezifunwayo zecandelo, kunye nezakhono ezithile zenkqubo yokuguqula i-CNC.
Isixhobo somatshini we-CNC kufuneka somelele ngokwaneleyo ukuze simelane nemikhosi yomatshini, kodwa kufuneka ikwazi ukumelana nobushushu kwaye inxibe.Ukongezelela, izinto eziphathekayo kufuneka zihambelane ne-coolant kunye ne-lubricants eya kusetyenziswa ngexesha lenkqubo yomatshini.Ukungaphumeleli ukukhetha imathiriyeli efanelekileyo kunokukhokelela ekubeni inxalenye ethile ingaphumeleli, ukulungiswa kweendleko ezinkulu, kunye nokwenzakala.
2) Ukunyamezela
Kuyo nayiphi na i-CNC yokujika icandelo loyilo, imingcipheko ethile efihliweyo inokuhlala ibangela ukuba inxalenye ibe ngaphandle kokunyamezela.Izizathu zale mingcipheko inokuba mininzi kwaye ihluke, kodwa kaninzi inokulandelwa emva koyilo lwenxalenye ngokwayo.Ukuze kuncitshiswe umngcipheko weengxaki ezenzekayo, kubalulekile ukuba umyili anike ingqwalasela efanelekileyo kumbandela wokunyamezelana komatshini kuyilo lwabo.
Ukuba i-dimension iqinile kakhulu, akunakwenzeka ukufezekisa iziphumo ezifunwayo.Ukuba i-dimension ikhululekile kakhulu, ngoko ukulungelelaniswa kunye nomsebenzi wenxalenye unokuphazamiseka.Ngenxa yoko, kuyafuneka ukuba kubekho ulungelelwano phakathi kwezi zinto zimbini zigqithisileyo.Eyona ndlela ilungileyo yokwenza oku kukusebenzisa ukunyamezelana okufanelekileyo kwisicelo.Ngokomzekelo, ukunyamezela okusondeleyo kudla ngokusetyenziswa kumacandelo achanekileyo, ngelixa ukunyamezela okukhululekile kuxolela ngakumbi kwaye kunokunceda ukunciphisa iindleko.
3) Ukugqitywa komphezulu
Xa kuqwalaselwa uyilo lweCNC Turned Part, ukugqitywa komphezulu yinto ebalulekileyo ekufuneka iqwalaselwe.Ukufezekisa ukugqiba okufunwayo kunokuba ngumngeni, kwaye ukukhetha okungalunganga kwezinto okanye izixhobo kunokukhokelela kwiziphumo ezimbi.Inxalenye enomphezulu ongekho mgangathweni inokubandezeleka kwiingxaki ezininzi, kubandakanya ukukhuhlana okwandileyo, ukunxiba okugqithisileyo, kunye nokuncipha kokutsala umdla wobuhle.
Ngokwahlukileyo, inxalenye enomgangatho ophezulu wokugqitywa komphezulu iya kusebenza ngokutyibilikayo nangobuchule kwaye iya kujongeka inomtsalane.Xa ukhetha ukugqitywa kwendawo ye-CNC-turned part, kubalulekile ukuqwalasela iimfuno zesicelo.Ngokomzekelo, ukugqitywa kwe-rougher kunokwamkeleka kwinxalenye yangaphakathi engayi kubonwa, ngelixa ukugqiba ngokukhawuleza kunokufuneka kwinxalenye yangaphandle ebonakalayo.
4) Ukuhlamba kunye nokuhlambulula
Xa uyila ngokuchanekileyo i-CNC-iguqulwe inxalenye, kubalulekile ukuqwalasela inkqubo yokudibanisa kunye ne-grooving.I-threading ibonelela ngendlela yokubopha iziqwenga ezibini kunye ngokuzidibanisa, ngelixa i-grooving ivumela inguqu egudileyo phakathi kweendawo ezimbini.Xa zisetyenziswe ngokubambisana, ezi mpawu zimbini zinokunceda ukudala umdibaniso oqinileyo onokumelana nemithwalo ephezulu.
Ukongezelela, ezi mpawu zingasetyenziselwa ukuphucula isibheno sobuhle benxalenye ngokufihla amajoyina okanye ukudala iipatheni ezinomdla.Ngenxa yoko, ukudibanisa ezi mpawu kuyilo oluyinxalenye kunganceda ukuphucula ukhuseleko, ukuqina, kunye nokusebenza kwemveliso.
5) Ubukhulu bendonga
Ubukhulu bendonga yenye into ekufuneka uyiqwalasele xa uyila iinxalenye ezijikiweyo ze-CNC.Ukuba ubukhulu bodonga buncinci kakhulu, inxalenye ingaba buthathaka kwaye iyakwazi ukuphuka.Nangona kunjalo, ukuba ubukhulu bodonga bukhulu kakhulu, inxalenye ingaba nzima kwaye kunzima ukuyiphatha.
Ubukhulu bodonga olufanelekileyo lwenxalenye ye-CNC ejikiweyo buya kuxhomekeka kwizinto ezisetyenzisiweyo kunye namandla afunekayo emveliso egqityiweyo.Ngokubanzi, nangona kunjalo, umthetho olungileyo wesithupha kukugcina iindonga zincinci kangangoko kunokwenzeka ngelixa zigcina amandla kunye nokuqina.Ngokunikela ingqalelo ngononophelo kubunzima beendonga, iinjineli zinokuqinisekisa ukuba iinxalenye zomelele kwaye ziyonga imali.
