CNC Machining Nquma Inani Cutting
Ohlelweni lwe-NC, umdidiyeli wohlelo kufanele anqume inani elinqunyiwe lenqubo ngayinye futhi alibhale ohlelweni ngendlela yemiyalelo. Imingcele yokusika ihlanganisa isivinini sokuphotha, inani lokusika emuva kanye nesivinini sokuphakelayo. Ngezindlela ezahlukene zokucubungula, imingcele yokusika ehlukene idinga ukukhethwa. Umgomo wokukhetha yenani lokusika uwukuqinisekisa ukunemba komshini kanye nobulukhuni bezingxenye, ukunikeza ukudlala okugcwele ekusebenzeni kokusika kwethuluzi, ukuqinisekisa ukuqina kwethuluzi okunengqondo, nokunikeza ukudlala okugcwele ekusebenzeni kwethuluzi lomshini ukuze kwandiswe ukukhiqiza. futhi unciphise izindleko.
1. Thola isivinini se-Spindle
Ijubane lokuphotha kufanele likhethwe ngokuya ngesivinini esivumelekile sokusika kanye nobubanzi be-workpiece (noma ithuluzi). Ifomula yokubala ithi: n=1000 v/7 1D kuphi: v? isivinini sokusika, iyunithi ingukunyakaza kwe-m/m, okunqunywa ukuqina kwethuluzi; n ijubane lokuphotha, iyunithi ingu-r/min, futhi D ingububanzi bocezu lokusebenza Noma ububanzi bethuluzi, ngo-mm. Ngesivinini esibaliwe sokuphotha n, isivinini ithuluzi lomshini elinalo noma eliseduze nalo kufanele sikhethwe ekugcineni.
2. Thola Izinga Lokuphakelayo
Ijubane lokuphakelayo liyipharamitha ebalulekile kumapharamitha wokusika wamathuluzi omshini we-CNC, akhethwa ngokuyinhloko ngokuya ngokunemba kwemishini kanye nezidingo zokuqina kwendawo yezingxenye kanye nezakhiwo ezibonakalayo zamathuluzi nezinto zokusebenza. Izinga lokuphakelayo eliphezulu likhawulelwe ukuqina kwethuluzi lomshini nokusebenza kwesistimu yokuphakelayo. Umgomo wokunquma izinga lokuphakelayo: Lapho izidingo zekhwalithi zengcezu yokusebenza zingaqinisekiswa, ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza, izinga eliphezulu lokuphakela lingakhethwa. Ngokuvamile kukhethwe ebangeni lika-100-200mm/min; lapho usika, ucubungula izimbobo ezijulile noma ucutshungulwa ngamathuluzi ensimbi anesivinini esikhulu, kuyafaneleka ukukhetha isivinini esiphansi sokuphakelayo, ngokuvamile esikhethwe ebangeni le-20-50mm/min; lapho ukunemba kokucubungula, indawo engaphezulu Lapho imfuneko yobunzima iphezulu, isivinini sokuphakela kufanele sikhethwe sibe sincane, ngokuvamile ebangeni lika-20-50mm/min; lapho ithuluzi lingenalutho, ikakhulukazi uma ibanga elide "libuyela ku-zero", ungasetha izilungiselelo zesistimu ye-CNC yethuluzi lomshini Izinga eliphezulu lokuphakelayo.
3. Thola inani lamathuluzi angemuva
Inani lokubanjwa emuva linqunywa ukuqina kwethuluzi lomshini, ithuluzi lomsebenzi kanye nethuluzi lokusika. Uma ukuqina kuvumela, inani lokubamba emuva kufanele lilingane nemvume yomshini we-workpiece ngangokunokwenzeka, okungase kunciphise inani lokudlula futhi kuthuthukise ukusebenza kahle kokukhiqiza. Ukuze kuqinisekiswe ikhwalithi yendawo eyenziwe ngomshini, inani elincane lesibonelelo sokuqeda lingashiywa, ngokuvamile li-0.2-0.5mm. Ngamafuphi, inani elithile lenani lokusika kufanele linqunywe ngokufanisa ngokusekelwe ekusebenzeni kwethuluzi lomshini, amamanuwali ahlobene nolwazi lwangempela.
Ngesikhathi esifanayo, ijubane lokuphotha, ukujula kokusika kanye nesivinini sokuphakela kungashintshwa komunye nomunye ukuze kwakhiwe inani elingcono kakhulu lokusika.
Inani lokusika akuyona nje ipharamitha ebalulekile okufanele inqunywe ngaphambi kokuba ithuluzi lomshini lilungiswe, kodwa futhi ukuthi inani lalo linengqondo noma cha linethonya elibaluleke kakhulu kwikhwalithi yokucubungula, ukusebenza kahle kokucubungula, kanye nezindleko zokukhiqiza. Inani lokusika elibizwa ngokuthi "elinengqondo" lisho inani lokusika elisebenzisa ngokugcwele ukusebenza kokusika kwethuluzi kanye nokusebenza okuguquguqukayo (amandla, i-torque) yethuluzi lomshini ukuthola ukukhiqiza okuphezulu kanye nezindleko eziphansi zokucubungula ngaphansi kwesisekelo se- ukuqinisekisa izinga.
Ithiphu yalolu hlobo lwethuluzi lokujika lakhiwe imiphetho eqondile eyinhloko neyesibili yokusika, njengamathuluzi okujika angama-900 angaphakathi nangaphandle, amathuluzi okuguqula ubuso kwesokunxele nakwesokudla, amathuluzi okujika ama-grooving (akusike), kanye nemiphetho ehlukahlukene yokusika yangaphandle neyangaphakathi ama-tip chamfers amancane. Ithuluzi lokuvula imbobo. Indlela yokukhetha yamapharamitha wejiyomethri wethuluzi lokujika elicijile (ikakhulukazi i-engeli yejometri) ngokuyisisekelo iyafana naleyo yokujika okuvamile, kodwa izici zomshini we-CNC (njengomzila womshini, ukuphazamiseka kwemishini, njll.) kufanele zicatshangelwe ngokugcwele. , futhi ithiphu lamathuluzi ngokwalo kufanele libhekwe njengamandla.
