Ekukhiqizeni ngobuningi beUkunemba kwe-CNCizingxenye ze-hardware zicutshungulwa, ngoba i-workpiece idinga ukunemba okuphezulu kanye nesikhathi esifushane sokulethwa, ukusebenza kahle kwemishini yinto ehamba phambili yokukhiqiza nokucubungula.Ukwazi ukubamba ulwazi olulula oluyisisekelo akukwazi nje ukuthuthukisa ukukhiqiza kokucubungula izesekeli zehadiwe, kodwa futhi kunciphise izinga lokuhluleka kwemishini ngesikhathi sokusetshenziswa.
Ake ngikutshele ulwazi oluyisisekeloCNCukunemba kwezingxenye zehadiwe ukucutshungulwa
1. Ukulawulwa kwe-chip
Ama-chips abambene eduze kwethuluzi noma ucezu lomsebenzi ukuze kusike isikhathi eside kulandelana.Ngokuvamile kubangelwa ukuphakela okuphansi, ukujula okuphansi kanye/noma okungajulile kokusikwa kwejiyomethri.
isizathu:
(1) Isiphakeli se-groove ekhethiwe siphansi kakhulu.
Isixazululo: Okuphakelayo okuqhubekayo.
(2) Ukujula kokusika komsele okhethiwe akushoni kakhulu.
Isixazululo: Khetha i-blade geometry ene-chip breaking eqinile.Khulisa izinga lokugeleza kokupholisa.
(3) I-radius yekhala yethuluzi inkulu kakhulu.
Isixazululo: Engeza ukujula kokusika noma khetha i-geometry eqinile yokuphulwa kwe-chip.
(4) I-engeli yokungena engafanele.
Isixazululo: Khetha indawo engaba yikhala elincane.
2. Ikhwalithi yokubukeka
Ibukeka futhi izwakala "inoboya" ngokubukeka futhi ayihlangabezani nezidingo zomsebenzi womphakathi.
isizathu:
(1) Ukuphulwa kwe-chip kudlula ezingxenyeni ezishayayo futhi kushiye imikhondo endaweni ecutshunguliwe.
Isixazululo: Khetha umumo we-groove oqondisa ukukhishwa kwe-chip.Shintsha i-engeli yokungena, wehlise ukujula kokusika, bese ukhetha isistimu yethuluzi le-rake eqondile ngokuthambekela kwensingo emaphakathi.
(2) Isizathu sokubukeka okunoboya ukuthi ukugqokwa kwe-groove onqenqemeni lokusika kuqine kakhulu.
Isixazululo: Khetha ibhrendi ene-oxidation engcono futhi ukumelana nokugqokwa, njengomkhiqizo we-cermet, futhi ulungise ukuze unciphise isivinini sokusika.
(3) Inhlanganisela yokuphakelayo okuphezulu kakhulu kanye nefillet yethiphu yethuluzi elincane izophumela ekubukekeni okumaholo.
Isixazululo: Khetha indawo enkulu yekhala yethuluzi kanye nesiphakeli esiphansi.
3. Ukwakheka kwe-Burr
Lapho usika kude ne-workpiece, i-burr yenziwa ekugcineni kokusika.
isizathu:
(1) Unqenqema lokusika alubukhali.
Isixazululo: Sebenzisa ama-blade anemiphetho ebukhali yokusika: -Ama-blade okugaya amahle anesilinganiso esincane sokuphakela (<0.1mm/r).
(2) Isiphakeli siphansi kakhulu ukuba singaba yindilinga yonqenqema lokusika.
Isixazululo: Sebenzisa isibambi sethuluzi esine-engeli encane yokungena.
(3) Ukuguga kwe-groove noma ukucwiliswa ekujuleni kwe-Ukunemba kwe-CNCukucubungula ihadiwe.
Isixazululo: Uma ushiya ucezu lokusebenza, qedela ukusika nge-chamfer noma i-radius.
4. Ukunyakaziswa
Amandla okusika ama-radial aphezulu, imbangela: i-oscillation noma imihuzuko evevezelayo ebangelwa ithuluzi noma idivayisi yethuluzi.Ngokuvamile, kubonakala lapho ibha eyisicefe isetshenziselwa umshini wangaphakathi wombuthano.
isizathu:
(1) I-engeli yokungena engafanele.
Isixazululo: Khetha i-engeli enkulu yokufaka (kr=90°).
(2) I-radius yekhala yethuluzi inkulu kakhulu.
Isixazululo: Khetha indawo encane yekhala.
(3) Ukuzulazula okungalungile, noma i-chamfering engalungile.
Isixazululo: Khetha uphawu lokuhweba olunoqweqwe oluncane, noma uphawu lokuhweba olungamboziwe.
(4) Ukugqoka kwe-flank ngokweqile onqenqemeni lokusika.
Isixazululo: Khetha uphawu lokuthengisa olungagugi kakhulu noma ulungise ukuze unciphise isivinini sokusika.
