Ngomshini we-CNC, ukuhlela kubaluleke kakhulu, okuthinta ngokuqondile ikhwalithi nokusebenza kahle komshini.Ngakho-ke ungawaqonda kanjani ngokushesha amakhono okuhlela wezikhungo zemishini ye-CNC?Masifunde ndawonye!
Umyalo wokumisa okwesikhashana, i-G04X(U)_/P_ ibhekisela esikhathini sokumisa ithuluzi (ukumisa okuphakelayo, i-spindle ayimi), inani elingemva kwekheli elithi P noma u-X isikhathi sokumisa okwesikhashana.Inani elingemva kuka-X kumelwe libe nephoyinti ledesimali, ngaphandle kwalokho libalwa njengengxenye eyinkulungwane yenani, kumasekhondi (amasekhondi), futhi inani elingemva kuka-P alikwazi ukuba nephoyinti ledesimali (okungukuthi, ukumelwa kwenombolo ephelele), ngama-millisecond (ms) .Kodwa-ke, kweminye imiyalo yokwenza imishini yesistimu yezimbobo (efana ne-G82, G88 ne-G89), ukuze kuqinisekiswe ukuthi imbobo ilukhuni, kudingeka isikhathi sokumisa isikhashana lapho ithuluzi lifika phansi kwembobo.Ngalesi sikhathi, ingamelwa kuphela ikheli elithi P. Ikheli X libonisa ukuthi isistimu yokulawula ibheka u-X njengenani lokuxhumanisa i-X-eksisi okufanele lisetshenziswe.
Umehluko nokuxhumana phakathi kwe-M00, M01, M02 kanye ne-M03, i-M00 iwumyalo wokumisa isikhashana wohlelo ongenamibandela.Lapho uhlelo lwenziwa, i-feed iyama futhi i-spindle iyama.Ukuze uqale kabusha uhlelo, kufanele uqale ubuyele kusimo se-JOG, cindezela u-CW (i-spindle forward rotation) ukuze uqale i-spindle, bese ubuyela esimweni se-AUTO, cindezela inkinobho ethi QALA ukuze uqale uhlelo.I-M01 wuhlelo olukhethayo lokumisa isikhashana umyalo.Ngaphambi kokuthi uhlelo lusetshenziswe, inkinobho ye-OPSTOP kuphaneli yokulawula kufanele ivulwe ukuze iluqalise.Umphumela ngemva kokubulawa uyafana nalowo we-M00.Ukuqalisa kabusha uhlelo kuyafana ngenhla.I-M00 ne-M01 zivame ukusetshenziselwa ukuhlola ubukhulu bengcezu yokusebenza noma ukukhishwa kwe-chip phakathi nokucutshungulwa.I-M02 iwumyalo wokuqeda uhlelo oluyinhloko.Uma lo myalo wenziwe, i-feed iyama, i-spindle iyama, futhi okokupholisa kuyavalwa.Kodwa ikhesa yohlelo iyama ekupheleni kohlelo.I-M30 iwumyalo oyinhloko wokuphela kohlelo.Umsebenzi uyafana ne-M02, umehluko wukuthi ikhesa ibuyela endaweni yekhanda lohlelo, kungakhathaliseki ukuthi akhona yini amanye amabhlogo ngemva kwe-M30.
Umyalo wokuhumusha oyisiyingi, i-G02 iwukuhunyushwa okuhambisana newashi, i-G03 iwukujobelela ngokuphambene newashi, endizeni ye-XY, ifomethi imi kanje: G02/G03X_Y_I_K_F_ noma G02/G03X_Y_R_F_, lapho u-X, Y kuyizixhumanisi zephoyinti lokugcina le-arc, I, J inani elikhulayo lephoyinti lokuqala le-arc enkabeni yesiyingi kuma-ax angu-X kanye no-Y, u-R uyi-arc radius, futhi u-F inani lokuphakelayo.Qaphela ukuthi uma u-q≤180°, u-R uyivelu ephozithivu;q>180°, R yinani elingaphansi;U-I kanye no-K kungabuye kucaciswe ngu-R. Uma kokubili kucaciswe ngesikhathi esifanayo, umyalo ka-R unokubaluleka, futhi I , K ayivumelekile;U-R akakwazi ukusika umbuthano ogcwele, futhi ukusika okuyindilinga ngokugcwele kungahlelwa kuphela ngo-I, J, K, ngoba kuneziyingi ezingenakubalwa ezinobubanzi obufanayo ngemva kokudlula endaweni efanayo.Uma mina no-K zinguziro, zingashiywa;kungakhathaliseki ukuthi iyiphi imodi ye-G90 noma ye-G91, I, J, K zihlelwe ngokuvumelana nezixhumanisi ezihlobene;ngesikhathi sokuhumusha okuyindilinga, umyalo wesinxephezelo samathuluzi G41/G42 awukwazi ukusetshenziswa.
