CNC Machining Amaphutha
Iphutha lejiyomethri le-fixture fixture ukwenza i-workpiece ilingane nethuluzi nethuluzi lomshini ngokuma okulungile, ngakho-ke iphutha lejometri lephutha le-fixture machining (ikakhulukazi iphutha lendawo) linomthelela omkhulu.
Iphutha lokumisa ikakhulukazi lihlanganisa iphutha ledatha yephutha kanye nephutha lokukhiqiza elingalungile lokuma kwepheya. Lapho i-workpiece icutshungulwa ethuluzini lomshini, kuyadingeka ukukhetha inani lezinto zejometri ku-workpiece njengedatha yokubeka ukuze icutshungulwe. Uma i-datum ekhethiwe yokuma kanye nedatha yokuklama (idatha esetshenziselwa ukunquma usayizi wendawo kanye nendawo kungxenye yomdwebo) ingashayisani, izoveza iphutha lokungafani kwedatha. Indawo okutholakala kuyo ucezu lokusebenza kanye nengxenye yendawo yokuhlanganisa kuhlanganisa indawo ebhangqiwe ndawonye. Ukuhluka okukhulu kwesikhundla socezu lokusebenza okubangelwa ukukhiqizwa okungalungile kwepheya etholakalayo kanye negebe lokuhlangana phakathi kwepheya elitholiwe libizwa ngokuthi iphutha lokukhiqiza elingalungile lepheya yokuthola. Iphutha lokukhiqiza elinganembi lokuma kwepheya lingakhiqizwa kuphela lapho kusetshenziswa indlela yokulungisa, kodwa hhayi endleleni yokusika isilingo.
Iphutha le-process system deformation ukuqina kwe-workpiece: uhlelo lwenqubo uma ukuqina kwe-workpiece kuhlobene nethuluzi lomshini, ithuluzi, ukulungiswa kuphansi kakhulu, ngaphansi kwesenzo samandla okusika, i-workpiece ngenxa yokuntuleka kokuqina okubangelwa ukuwohloka komshini.iphutha lomshiniinkulu uma kuqhathaniswa. Ukuqina kwethuluzi: ukuqina kwethuluzi lokujika eliyindilinga elingaphandle endaweni evamile (y) isiqondiso sendawo yomshini kukhulu kakhulu, futhi ukuguqulwa kwayo kunganakwa. Ukubhoboza imbobo yangaphakathi enobubanzi obuncane, ukuqina kwebha yamathuluzi kubi kakhulu, i-force deformation yebha yamathuluzi inomthelela omkhulu ekunembeni komshini wembobo.
Ukuqina kwezingxenye zamathuluzi omshini: izingxenye zamathuluzi omshini zakhiwe izingxenye eziningi. Kuze kube manje, ayikho indlela yokubala efanele futhi elula yokuqina kwezingxenye zamathuluzi omshini. Njengamanje, kunqunywa ikakhulukazi indlela yokuhlola. Izici ezithonya ukuqina kwezingxenye zamathuluzi omshini zihlanganisa ukuwohloka kokuxhumana kwendawo ehlangene, amandla okungqubuzana, izingxenye zokuqina okuphansi kanye nokucaciswa.
Iphutha lejometri yethuluzi noma yiliphi ithuluzi enqubweni yokusika alinakugwenywa ukukhiqiza ukuguga, futhi ngaleyo ndlela kubangele usayizi nokuma kwe-workpiece ukushintsha. Umthelela wephutha lejiyomethri yethuluzi kuphutha lomshini uyahlukahluka ngezinhlobo ezahlukene zamathuluzi: uma usebenzisa amathuluzi okusika usayizi ongaguquki, iphutha lokukhiqiza ithuluzi lizothinta ngokuqondile ukunemba komshini womsebenzi; Kodwa-ke, ngethuluzi elivamile (elifana nethuluzi lokuvula), iphutha lokukhiqiza alinawo umthelela oqondile ephutheni lomshini.
