I-Graphite yinto eqhelekileyo engeyiyo yesinyithi, emnyama, enokumelana nobushushu obuphezulu nobuphantsi, ukuqhuba kakuhle kombane nobushushu, ukuthambisa okuhle kunye neempawu zeekhemikhali ezizinzileyo; ukuqhuba kakuhle kombane, ingasetyenziswa njenge-electrode kwi-EDM. Xa kuthelekiswa nee-electrode zendabuko zobhedu, i-graphite ineenzuzo ezininzi ezifana nokumelana nobushushu obuphezulu, ukusetyenziswa okuphantsi kokukhupha, kunye nokuguquguquka okuncinci kobushushu. Ibonisa ukuguquguquka okungcono ekucutshungulweni kwezinto ezichanekileyo nezintsonkothileyo kunye nee-electrode ezinkulu. Ithathe indawo yee-electrode zobhedu kancinci kancinci njengeentlantsi zombane. Eyona nto iphambili kwii-electrode zomatshini [1]. Ukongeza, izinto ezingagugiyo ze-graphite zingasetyenziswa phantsi kweemeko zesantya esiphezulu, ubushushu obuphezulu, kunye noxinzelelo oluphezulu ngaphandle kweoyile yokuthambisa. Izixhobo ezininzi zisebenzisa kakhulu iikomityi zepiston zezinto ze-graphite, izitywino kunye neebheringi
Okwangoku, izixhobo zegrafiti zisetyenziswa kakhulu kwicandelo loomatshini, i-metallurgy, ishishini leekhemikhali, ukhuselo lwesizwe kunye nezinye iinkalo. Kukho iintlobo ezininzi zeenxalenye zegrafiti, ulwakhiwo lweendawo oluntsonkothileyo, ukuchaneka okuphezulu kunye neemfuno zomgangatho womphezulu. Uphando lwasekhaya malunga nomatshini wokugaya igrafiti alunzulu ngokwaneleyo. Izixhobo zomatshini wokugaya igrafiti zasekhaya nazo zimbalwa kakhulu. Ukucubungula igrafiti yangaphandle kusebenzisa kakhulu amaziko okucubungula igrafiti ukucubungula ngesantya esiphezulu, ngoku eye yaba yindlela ephambili yophuhliso lomatshini wokugaya igrafiti.
Eli nqaku lihlalutya ikakhulu iteknoloji yoomatshini bokuchwetheza igrafiti kunye nezixhobo zoomatshini bokucubungula ukusuka kwezi nkalo zilandelayo.

Uhlalutyo lokusebenza kokusika igrafiti
I-Graphite yinto ebuthathaka enesakhiwo esahlukileyo. Ukusikwa kwe-graphite kufezekiswa ngokuvelisa amasuntswana e-chip angaqhubekiyo okanye umgubo ngokusebenzisa ukwaphuka okubuthathaka kwezinto ze-graphite. Ngokuphathelele indlela yokusika izinto ze-graphite, izazi zasekhaya nakwamanye amazwe zenze uphando oluninzi. Izazi zamanye amazwe zikholelwa ukuba inkqubo yokwenziwa kwe-graphite chip imalunga nokuba umda wokusika wesixhobo udibana nomsebenzi, kwaye incam yesixhobo iyatyunyuzwa, yenze iitships ezincinci kunye nemingxunya emincinci, kwaye kuvela umngxuma, oya kwanda uye ngaphambili nasezantsi kwencam yesixhobo, wenze umngxuma wokuqhekeka, kwaye inxalenye yomsebenzi iya kwaphuka ngenxa yokuqhubela phambili kwesixhobo, okwenza iitships. Izazi zasekhaya zikholelwa ukuba amasuntswana e-graphite alungile kakhulu, kwaye umda wokusika wesixhobo une-arc enkulu yencam, ngoko ke indima yomngxuma wokusika ifana nokukhupha. Izinto ze-graphite kwindawo yoqhagamshelwano lwesixhobo - umsebenzi ucinezelwa bubuso be-rake kunye nencam yesixhobo. Phantsi koxinzelelo, ukuqhekeka okubuthathaka kuveliswa, ngaloo ndlela kwenze iitships zokuqhekeza [3].
Kwinkqubo yokusika igrafiti, ngenxa yotshintsho kwicala lokusika leekona ezijikelezileyo okanye iikona zomsebenzi, utshintsho ekukhawuleziseni kwesixhobo somatshini, utshintsho kwicala kunye nekona yokusika ngaphakathi nangaphandle kwesixhobo, ukungcangcazela kokusika, njl.njl., impembelelo ethile ibangelwa kwigrafiti yomsebenzi, nto leyo ebangela umda wenxalenye yegrafiti. Ukuqhekeka kwekona kunye nokuqhekeka, ukuguguleka okukhulu kwesixhobo kunye nezinye iingxaki. Ingakumbi xa kusetyenzwa iikona kunye neendawo zegrafiti ezibhityileyo nezimxinwa, kunokwenzeka ukuba kubangele iikona kunye nokuqhekeka komsebenzi, nto leyo eye yaba yingxaki ekusetyenzweni kwegrafiti.
Inkqubo yokusika i-graphite 
Iindlela zemveli zokugaya izixhobo zegrafiti ziquka ukujika, ukugaya, ukugaya, ukusarha, njl.njl., kodwa zinokufezekiswa kuphela ukucutshungulwa kwamacandelo egrafiti ngeemilo ezilula kunye nokuchaneka okuphantsi. Ngophuhliso olukhawulezileyo kunye nokusetyenziswa kwamaziko okugaya akhawulezayo egrafiti, izixhobo zokusika, kunye neetekhnoloji ezixhasayo ezinxulumene noko, ezi ndlela zemveli zokugaya ziye zatshintshwa kancinci kancinci ziitekhnoloji zokugaya ezikhawulezayo. Ukuziqhelanisa kubonise ukuba: ngenxa yeempawu eziqinileyo nezibuthathaka zegrafiti, ukuguguleka kwezixhobo kuyingozi kakhulu ngexesha lokucubungula, ke ngoko, kuyacetyiswa ukusebenzisa izixhobo ezigqunywe nge-carbide okanye idayimani.
Amanyathelo enkqubo yokusika
Ngenxa yobuchule begrafiti, ukuze kufezekiswe ukucutshungulwa kweendawo zegrafiti ezisemgangathweni ophezulu, kufuneka kuthathwe amanyathelo enkqubo afanelekileyo ukuqinisekisa. Xa kucutshungulwa izinto zegrafiti, isixhobo sinokutya ngqo kwindawo yokusebenza, sisebenzisa iiparameter ezinkulu zokusika; ukuze kuthintelwe ukuqhekeka ngexesha lokugqiba, izixhobo ezinokumelana nokuguguleka okuhle zihlala zisetyenziselwa ukunciphisa ubungakanani bokusika besixhobo, kwaye Qinisekisa ukuba iphimbo lesixhobo sokusika lingaphantsi kwe-1/2 yobubanzi besixhobo, kwaye wenze amanyathelo enkqubo afana nokucutshungulwa kokunciphisa umbane xa kucutshungulwa omabini amacala [4].
Kwakhona kuyimfuneko ukucwangcisa ngokufanelekileyo indlela yokusika ngexesha lokusika. Xa kusetyenzwa i-contour yangaphakathi, i-contour ejikelezileyo kufuneka isetyenziswe kangangoko kunokwenzeka ukusika inxalenye yamandla yenxalenye enqunyiweyo ukuze ihlale ityebile kwaye iqine, kwaye kuthintelwe ukuba i-workpiece ingaphuki [5]. Xa kusetyenzwa iiplani okanye imingxunya, khetha ukutya okuthe tyaba okanye okujikelezayo kangangoko kunokwenzeka; kuphephe iziqithi kumphezulu wokusebenza wenxalenye, kwaye kuphephe ukusika i-workpiece kumphezulu wokusebenza.
Ukongeza, indlela yokusika ikwayinto ebalulekileyo echaphazela ukusika igrafiti. Ukungcangcazela kokusika ngexesha lokusila phantsi kungaphantsi koko kokusila phezulu. Ubukhulu bokusika besixhobo ngexesha lokusila phantsi buncitshiswa ukusuka kwi-high ukuya kwi-zero, kwaye akuyi kubakho nto ibangela ukutsiba emva kokuba isixhobo sinqumle kwindawo yokusebenza. Ke ngoko, ukusila phantsi kudla ngokukhethwa ukuze kusetyenzwe igrafiti.
Xa kusetyenzwa izinto zokusebenza zegrafiti ezinezakhiwo ezintsonkothileyo, ukongeza ekuphuculeni iteknoloji yokucubungula ngokusekelwe kwezi zinto zikhankanyiweyo apha ngasentla, kufuneka kuthathwe amanyathelo akhethekileyo ngokwemiqathango ethile ukuze kufunyanwe iziphumo ezilungileyo zokusika.
