Ukuxhumana Okuphakeme Phakathi Kwemibhalo Yokuphakama Nokusebenza Kwe-EDM
Abaningi abaningi abasebenzisa imishini ye-EDM bazi ukuthi ukugcina kwesifunda kuyisibonelo esingqayile kakhulu sokukhula kwezinto, kodwa abaningi bahlupha ukuthi okungu-80% kwezinye zezinye zokugcina, izihlangothi ezincinci, nokubhalwa kwezinto ezingavamile kusuka ku-ukulinganiswa okungafanele kwezinhlobo zezikhathi zokushaya, akusukela emiphumela yezinto zokusebenza. Ngaphandle kwezintshisekelo zokuvamisa ezintsha, imishini ye-EDM iyasebenzisa ukushaya kwamandla phakathi kwezinkampani nezinto zokusebenza ngokushaya kwezikhathi zokushaya, apho izinhlobo zezikhathi zokushaya ziyabhekisa ngqo amandla okushaya, ukuzimisa kwezikhathi zokushaya, nokuhambisana kokuvamisa kwezinto. Kukusebenzisa izinto zokufaka kwezifunda, izinto zokufaka kwezindawo zokufaka, nezinto zokufaka kwezindawo zokufaka, ukugcina okungafanele kuzoba nokuthi kubhaleka kakhulu ukugcina kwezifunda, ukuncipha ukulungiselela kwezinto, nokuphatha kwezinto zokusebenza.
Ngokubhekisele kumyaka eminingi yokuqondisa i-EDM esikhathini sezindawo nekukhuluma ngamashini, abasebenzi basebenzi be-EDM bafundiswe ukuthi ukuzama ukunciphisa isikhathi sokusebenza kuphela akakwazi ukuthuthukisa ububi lwesifunda esihlukile. Kufanele kube nesicelo sokuhlela isikhathi sokuphuma kwemiphasi, isikhathi sokungaphumi kwemiphasi, nokuvalelwa kwemiphasi yokuphuma ngokulinganisa izinto zokusebenza nezindawo zokusebenza ukuze kubalanciwe ubukhulu bekusebenza nokuthuthukisa ububi lwesifunda esihlukile. Lokhu kukhuluma ngokuphelele kubasebenzi bokusebenza okuhle kwezinto zokusebenza ezinkulu, kuyabizwa njengomthetho wokuthuthukisa okusebenzayo kwezindawo zokusebenza zezindawo zokusebenza zokusebenza kwezindawo zokusebenza.
Ukuhlela Okusebenzayo Kwesikhathi Sokuphuma Kwemiphasi Ukusebenza Kwisifunda Esihlukile
Ukugcina kwe-pulse kuyisikhathi sokugcina kwesiphephelo esisodwa kumashini we-EDM, okuyikho ekubhekisene nokukhala kwamaphuzu wokuphatha amafutha kusuka kwezinye zezinto ezihlukene. Ukugcina kwe-pulse okude kuvumela ukuthi kubhekiswe kakhulu kwezindawo zokuphatha amafutha ngasendaweni esisodwa, okukhulisa ukususa kwamathuba kwezinye zezinto ezihlukene kodwa kwenza amaphuzu amakhulu nezinde kahle okukhala kwezinye zezinto ezihlukene. Ngaphandle kwalokho, ukugcina kwe-pulse okufuphi kakhulu kuzimisa ukukhala kwamaphuzu amakhulu ngasendaweni esisodwa, okwenza ukuthi isikhali sibe yilungile futhi sibe yisikhathi esifanayo sokugcina kwezinye zezinto ezihlukene.
Kwizokwakha kwezinkulungwane zezinto ezihlukene zokusebenza kwe-die steel nezinkulungwane zezinto ezihlukene zokusebenza, iziphumo zokusebenza ngemva yezinsuku zokusebenza zibonisa ukuthi ukusetha isikhathi eside sokuphuma kwesiphepho kusenzo lokuqala kusiza ekuvuseleleni ukusebenza. Kuzokwakha kwezinsuku zokugcina, ukuguqula isikhathi sokuphuma kwesiphepho kuqala kubalulekile ukususa amaphutha emboni nezindawo ezingavamile zokuphatha. Kufanele sithi ukuthi ukugcina isikhathi sokuphuma kwesiphepho kungenzeka ngokuphelele. Isikhathi esincane kakhulu sokuphuma kwesiphepho kusiza ukuthi isiphepho asisikeleke kahle, kusiza ukuthi kubhekwe isiphepho esingavamile, futhi kusiza ukuthi kubhekwe amaphutha amaningi emboni. Ukusebenza okuhle kwezinkulungwane zokusebenza kuyikhethekho yokuguqula iziphakamiso ngokuphakama, ukugcina isikhathi sokuphuma kwesiphepho ngokuphakama kusenzo lokuqala kusenzo lokuqeda ukuvikela isikhathi sokugcina nokuvikela ukusebenza okuhle.
Ukugcina isikhathi sokungaphepho kwesiphepho ngokuhle ukususa izinkinga zokusebenza
Isikhathi sokuvalelwa kwe-pulse, isikhathi sesidlaliso phakathi kwezindlela zokuphuma kwezimbili ezingaphakathi, yindlela eyodwa ekufuneka ibe yisakhelo esibalulekile kubukhona kwezinkulungwane zomkhosi wemashini yokuqondisa isandla. Lokhu kusasa kusinika isikhathi esifanele ukuthi umsindo wokugcina uhlamule amasiko amahlanu ayo, uhlamule isikhathi sokuhlala kwezindawo zokuphuma, nokugcina ukuthi isikhathi sokuhlanza kwezindawo zokuphuma, okuyinto eyodwa ekufuneka ibe yisakhelo sokuvikela ukuphuma kwesibili nokubonakala kwezinkinga zokuhlanya isandla.
Imibiko yemithombo yomsebenzi yokuqondisa kubonisa ukuthi isikhathi esingafanele sokuvalelwa kwesipho (pulse off-time) kukhona ngokuphikisayo kokubonakala kwezinye izindawo zokugqibela kwe-EDM futhi kubonakala kwezindawo zokugqibela zokufa. Uma isikhathi sokuvalelwa kwesipho sifanele kakhulu, izinto ezingavumelekile ziyagcwaliswa emgcinweni wokugqibela okushengele, okuzosiza kumsho wokugqibela okungasemthethweni nokugqibela okungafanayo. Kumaqondiso okugqibela okujwayelekile, ukulandela isikhathi sokuvalelwa kwesipho ngezinguquko zombili ku zinhlanu zokuvula kwesipho (pulse on-time) kusiza ekugcwaliseni izinto ezingavumelekile futhi ekugcineni ukuthi isipho siyasebenza ngendlela efanele. Kumaqondiso awaphambili okugqibela okwamanzi amaningi nezindawo ezincane, okuyisiphelo sokugcwalisa izinto ezingavumelekile, kufanele ukuthi isikhathi sokuvalelwa kwesipho sibutheleke ukuze sibuye sibonelela imiphumela yokugcwalisa izinto ezingavumelekile. Ngakumbi, ukuthi isikhathi sokuvalelwa kwesipho sibe khulu kakhulu kuyakhiya ubuncinane bekusebenza kwegxilo, ngakho-ke ukulandela umphumo wokugqibela ngokudlula kwezindawo zokugqibela kufanele ukuze kube nemiphumela emihle futhi ekusebenzeni ngokuhle kwegxilo yokuqondisa.
Ukulinganisa Kwesikhathi Sokukhanya Okuphezulu Kumaqondiso Okugqibela Okunamandla
I-peak current imelela i-instantaneous maximum current of single spark discharge emshinini we-EDM, osebenza njenge-parameter eyinhloko yokulawula amandla okukhipha amandla. I-peak current ephezulu inikeza amandla amakhulu okuqhekeka kwensimbi, afanelekile ukususwa kwezinto ezinkulu ekucutshungweni okungahleliwe, kepha kuzokwakha izingqimba ezibonakalayo ezishiswe ukushisa kanye nama-crater amakhulu ebusweni bendawo yokusebenza, okuthinta kakhulu ukunemba kokuphela kobuso.
