Inqubo yokukhetha abasiki bokugaya ngokuvamile ibheka izici ezilandelayo okufanele zikhethwe

1, Inqubo yokukhetha abasiki bokugaya ngokuvamile ibheka izici ezilandelayo okufanele zikhethwe:

(1) Ukuma kwengxenye (uma kucatshangelwa iphrofayili yokucubungula): Iphrofayili yokucubungula ngokuvamile ingaba yisicaba, ijulile, imbobo, intambo, njll. Amathuluzi asetshenziselwa amaphrofayili okucubungula ahlukene ahlukile. Isibonelo, umsiki wokugaya i-fillet angagaya izindawo eziqondile, kodwa hhayi izindawo eziqondile zokugaya.
 
(2) Izinto: Cabanga ngobuchwepheshe bayo bokusebenza, ukwakheka kwe-chip, ubulukhuni kanye nezinto zokuhlanganisa. Abakhiqizi bamathuluzi ngokuvamile bahlukanisa izinto zibe yinsimbi, insimbi engagqwali, insimbi ephonswe ngensimbi, izinsimbi ezingezona i-ferrous, ama-super alloys, ama-titanium alloys kanye nezinto eziqinile.
 
(3) Izimo zomshini: Izimo zomshini zifaka phakathi ukuqina kohlelo lokusebenza lwento yomshini, isimo sokubambelela kwesibambi samathuluzi njalo njalo.
 
(4) Ukuzinza kohlelo lwethuluzi lomshini, i-fixture, i-workpiece: Lokhu kudinga ukuqonda amandla atholakalayo ethuluzi lomshini, uhlobo lwe-spindle kanye nemininingwane, ubudala bethuluzi lomshini, njll., kanye ne-overhang ende yesibambi samathuluzi kanye nesimo saso sokugeleza kwe-axial/radial.
 
(4) Isigaba sokucubungula kanye nesigaba esincane: Lokhu kufaka phakathi ukugaya amahlombe, ukugaya ngendiza, ukugaya iphrofayili, njll., okudingeka kuhlanganiswe nezici zethuluzi lokukhetha ithuluzi.

2. Ukukhethwa kwe-engeli yejometri yomsiki wokugaya
 
(1) Ukukhetha i-engeli engaphambili. I-engeli ye-rake ye-milling cutter kufanele inqunywe ngokwezinto ezisetshenziswa yithuluzi kanye nomsebenzi. Ngokuvamile kuba khona imiphumela ekugayweni, ngakho-ke kubalulekile ukuqinisekisa ukuthi unqenqema lokusika lunamandla aphezulu. Ngokuvamile, i-engeli ye-rake ye-milling cutter incane kune-engeli ye-rake yokusika yethuluzi lokujika; insimbi yesivinini esikhulu inkulu kunethuluzi le-carbide eliqiniswe ngosimende; ngaphezu kwalokho, lapho kugaywa izinto zepulasitiki, ngenxa yokuguquguquka okukhulu kokusika, kufanele kusetshenziswe i-engeli enkulu ye-rake; lapho kugaywa izinto ezibuthakathaka, i-engeli ye-rake kufanele ibe yincane; lapho kucutshungulwa izinto ezinamandla aphezulu nobunzima, i-engeli ye-rake engemihle nayo ingasetshenziswa.
 
(2) Ukukhetha ukuthambekela kwe-blade. I-helix angle β yesiyingi sangaphandle se-end mill kanye ne-cylindrical milling cutter yi-blade intensity λ s. Lokhu kwenza amazinyo okusika angakwazi ukusika kancane kancane ngaphakathi nangaphandle kwe-workpiece, kuthuthukiswe ukushelela kokugaya. Ukwandisa i-β kungandisa i-rake angle yangempela, kucije umkhawulo wokusika, futhi kwenze kube lula ukukhipha ama-chips. Kwabasiki bokugaya abanobubanzi obuncane bokugaya, ukwandisa i-helix angle β akubalulekile kangako, ngakho-ke i-β=0 noma inani elincane ngokuvamile liyathathwa.
 
(3) Ukukhetha i-engeli yokuphambuka eyinhloko kanye ne-engeli yokuphambuka yesibili. Umphumela we-engeli yokungena yesikhiphi sokugaya ubuso kanye nomthelela wayo enqubweni yokugaya ufana nowe-engeli yokungena yethuluzi lokujika ekuphenduleni. Ama-engeli okungena asetshenziswa kakhulu angama-45°, 60°, 75°, kanye nama-90°. Ukuqina kohlelo lwenqubo kuhle, futhi inani elincane liyasetshenziswa; ngaphandle kwalokho, inani elikhulu liyasetshenziswa, futhi ukukhetha i-engeli yokungena kuboniswe kuThebula 4-3. I-engeli yokuphambuka yesibili ngokuvamile ingu-5°～10°. Isikhiphi sokugaya esiyindilinga sinomkhawulo wokusika oyinhloko kuphela futhi asinawo umkhawulo wokusika wesibili, ngakho-ke akukho-engeli yokuphambuka yesibili, futhi i-engeli yokungena ingu-90°.
