F: lebelo la ho fepa (mm/min)

 

M: palo ea likhahla tse khaohang

 

FN: palo ea lisebelisoa (mm/revolution)

 

Ho fokotsa palo ea moeli o mong le o mong: FN = Z × FZ

 

Z: palo ea li-blades tsa sesebelisoa

 

FZ: palo ea moeli o mong le o mong oa sesebelisoa (mm/revolution)

 

6. Qala ho sebetsa

 

Qalong ea lenaneo ka leng, hoa hlokahala ho hlahloba ka hloko hore na sesebelisoa se sebelisitsoeng ke sona se boletsoeng bukeng ea litaelo. Qalong ea machining, lebelo la phepelo le tla fetoloa ho bonyane le ho etsoa karolong e le 'ngoe. Ha e beha, e theoha, 'me e fepa ka potlako, e lokela ho tsepamisa mohopolo. Haeba ho na le bothata ka senotlolo sa stop, emisa hang-hang. Ela hloko ho ela hloko tsela e tsamaeang ea sehahi ho netefatsa phepo e sireletsehileng, ebe butle-butle eketsa lebelo la phepo ho ea boemong bo loketseng. Ka nako e ts'oanang, eketsa moea o pholileng kapa o batang ho sehahi, le workpieworkpieceho sebetsa ka thata ha hoa lokela ho ba hole haholo le phanele ea taolo, 'me mochini o tla emisoa hore o hlahlojoe haeba ho na le ntho e sa tloaelehang.

 

Kamora ho otlolla, hula mitha hape ho netefatsa hore workpieworkpiece e hlephile. Haeba e teng, e tlameha ho lokisoa hape le ho angoa.

 

Mekhahlelo ea ts'ebetso e lula e ntlafatsoa ho fihlela phello e ntle ea ts'ebetso.

 

Kaha ts'ebetso ena e bohlokoa, ka mor'a hore workpieworkpiece e felisoe, boleng ba tekanyo ea mantlha bo tla lekanyetsoa ho bona hore na bo lumellana le litlhoko tsa ho taka. Haeba ho na le bothata leha e le bofe, hang-hang tsebisa moeta-pele oa sehlopha kapa moqapi oa lenaneo ea mosebetsing ho le hlahloba le ho le rarolla. E ka tlosoa ka mor'a ho feta ho itlhahloba 'me e tlameha ho romeloa ho mohlahlobi bakeng sa tlhahlobo e khethehileng.

 

Mofuta oa ts'ebetso: ts'ebetso ea lesoba: pele ho cheka setsing sa ts'ebetso, setsi sa ho phunya se tlameha ho sebelisoa bakeng sa boemo, ebe karoloana ea ho phunya 0.5 ~ 2mm e nyane ho feta boholo ba ho taka e tla sebelisoa bakeng sa ho cheka, 'me qetellong, ho tla sebelisoa hanyenyane e loketseng. bakeng sa ho qeta.

 

Reaming processing: ho tsosolosa workpieworkpiece, sebelisa setsi sa ho phunya bakeng sa ho beha boemo, ebe u sebelisa drill bits 0.5 ~ 0.3mm e nyane ho feta boholo ba setšoantšo ho phunya, 'me qetellong, sebelisa reamer ho tsosolosa lesoba. Ela hloko ho laola lebelo la spindle ka hare ho 70 ~ 180rpm / min nakong ea ho tsosolosa.

 

Ts'ebetso e tenang: bakeng sa ts'ebetso e tenang ea li-workpieworkpieces, sebelisa setsi sa ho phunya ho fumana, ebe u sebelisa sekhechana sa drill, se nyane ka 1-2mm ho feta saese ea setšoantšo, ebe u sebelisa seha se mahoashe se boring (kapa sekhechana sa milling) ho se etsa. Lehlakore le letšehali le nang le tumello ea machining e ka bang 0.3mm feela, 'me qetellong sebelisa sehahi se setle se nang le boholo bo lokiselitsoeng esale pele ho qeta ho tena, le ho teneha ho qetela. tumello ha ea lokela ho ba ka tlase ho 0.1mm.

 

Ts'ebetso ea taolo ea linomoro ka kotloloho (DNC): pele ho ts'ebetso ea taolo ea linomoro tsa DNC, workpieworkpiecebe e koetsoe, boemo ba zero bo tla beoa, 'me li-parameter li tla beoa. Bula lenaneo la ts'ebetso le tla fetisetsoa khomphuteng bakeng sa tlhahlobo, ebe u lumella k'homphieutha hore e kene sebakeng sa DNC ebe e kenya lebitso la faele ea lenaneo le nepahetseng la ho sebetsa. Daren micro signal: mujuren e tobetsa konopo e hatisitsoeng, 'me lenaneo le qala senotlolo mochineng oa mochine,' me lentsoe LSK le benya holim'a mochine oa mochine. Tobetsa keyboard e kentsoeng khomphuteng ho sebetsa phetiso ea data ea DNC.

 

7. Likahare le ho itlhahloba ka bophara

 

Pele ho ts'ebetso, processor e tlameha ho bona litaba tsa karete ea ts'ebetso, e tsebe ka ho hlaka likarolo tse lokelang ho sebetsoa, ​​libopeho le boholo ba litšoantšo, 'me e bone litaba tsa ts'ebetso ea nfollowingprocess.

 

Pele ho workpieworkpieceng, lekanya hore na boholo bo se nang letho bo finyella litlhoko tsa ho taka, 'me u hlahlobe hore na ho behoa ha workpieworkpiecesistent ho lumellana le litaelo tsa ts'ebetso ea lenaneo.

 

Ho itlhahloba ho tla etsoa ka mor'a ho sebetsa ka thata ho lokisa lintlha bakeng sa liphoso ka nako. Likahare tsa ho itlhahloba li bua haholo ka boemo le boholo ba likarolo tsa ts'ebetso. Ka mohlala, boemo ba boemo pakeng tsa likarolo tsa ho sebetsa, hore na workpiece e arotsoe ka tsela e nepahetseng, hore na tekanyo e tsoang karolong ea ho sebetsa ho ea moeling oa litšupiso (ntlha ea boitsebiso) e kopana le tlhokahalo ea ho taka, le boemo ba boemo pakeng tsa likarolo tsa ho sebetsa. Ka mor'a ho hlahloba boemo le boholo, lekanya 'musi oa sebopeho se sa sebetseng (ntle le arc).

 

Qetella machining e ka etsoa feela ka mor'a ho sebetsa ka thata le ho itlhahloba. Kamora ho qeta, basebetsi ba tla itlhahloba ka sebopeho le boholo ba likarolo tse sebetsitsoeng: lekola bolelele le bophara ba likarolo tse otlolohileng tsa sebaka se otlolohileng mme ba lekanye boholo ba ntlha e tšoailoeng setšoantšong bakeng sa likarolo tse sebetsitsoeng. bokahodimo bo sekametseng.

 

Basebeletsi ba ka tlosa workpiece 'me ba e romela ho mohlahlobi bakeng sa tlhahlobo e khethehileng ka mor'a ho qeta ho itlhahloba mosebetsing, ho tiisa hore e lumellana le litšoantšo le litlhoko tsa ts'ebetso.
