Indlela yokugaya i-end Mill
Kwinkqubo yokusila, iindawo zokusila zinokwahlulwa zibe ziindidi ezimbini: ukungqusha phantsi kunye nokunyuka, ngokobudlelwane phakathi kolwalathiso olujikelezayo lwesixhobo sokusila kunye nesalathiso sokusika ukutya. Xa ulwalathiso olujikelezayo lwe-milling cutter lufana ne-workpiece feed direction, ibizwa ngokuba yi-click milling. Isalathiso esijikelezayo somsiki wokusila sichasene nesalathiso sokutya kwesixhobo sokusebenza, esibizwa ngokuba yi-up-cut milling.
Ukucola ukukhwela ngokuqhelekileyo kusetyenziswa kwimveliso yokwenyani. Amandla asetyenziswayo kwi-down milling incinci kune-up milling. Ngaphantsi kweemeko ezifanayo zokusika, ukusetyenziswa kwamandla okunciphisa i-5% ukuya kwi-15% ephantsi, kwaye kulungele ngakumbi ukususwa kwetshiphu. Ngokuqhelekileyo, indlela yokugaya i-down-milling kufuneka isetyenziswe ngokusemandleni ukuphucula umphezulu wokugqiba (ukunciphisa uburhabaxa) beendawo ezenziwe ngoomatshini kunye nokuqinisekisa ukuchaneka kwe-dimensional. Nangona kunjalo, xa kukho umaleko onzima, ukuqokelela kwe-slag kwindawo yokusika, kwaye umphezulu we-workpiece awulingani, njengokwenza i-machining forging blanks, kufuneka kusetyenziswe indlela yokugaya.
Ngexesha lokunyuka kokugaya, ukusika kuyatshintsha ukusuka kwingqimba ukuya kwincinci, kwaye amazinyo omthi anqunyulwe kwindawo engabonakaliyo, eyinzuzo ekusebenziseni abasiki be-milling. Ngexesha lokusila, xa amazinyo okusika we-milling cutter enxibelelana nomsebenzi, akakwazi ukusika ngokukhawuleza kumaleko esinyithi, kodwa isilayidi umgama omfutshane kumphezulu womsebenzi. Kulula ukwenza umaleko oqinileyo, onciphisa ukuqina kwesixhobo, uchaphazela ukugqitywa komphezulu we-workpiece, kwaye uzisa ukungonakali ukusika.
Ukongeza, ngexesha lokusila, ekubeni amazinyo okusika anqunyulwa ukusuka ezantsi ukuya phezulu (okanye ukusuka ngaphakathi ukuya ngaphandle), kwaye ukusika kuqala ukusuka kumphezulu oqinileyo, amazinyo okusika aphantsi komthwalo omkhulu wempembelelo, kwaye i-milling cutter iba buthuntu ngokukhawuleza, kodwa amazinyo okusika ayasikwa. Ukunyuka kwe-milling kunye ne-down milling, kuba ubukhulu bokusika buhluke xa usika kwi-workpiece, kunye nobude boqhagamshelwano phakathi kwamazinyo okusika kunye ne-workpiece yahlukile, ngoko ke iqondo lokunxiba le-milling cutter lihlukile. Uqheliselo lubonisa ukuba ukuqina komatshini wokusila kuku-2 ukuya ku-3 ngaphezulu kunolo lokusila kwi-milling ephantsi. amaxesha, uburhabaxa bomphezulu bunokuncitshiswa. Kodwa ukukhwela ukukhwela akufanelanga ukugaya izixhobo zokusebenza ezinolusu oluqinileyo.
