CNC Machining Center ayenera kuchita zinthu izi bwino kudula zitsulo

Choyamba, kutembenuka kusuntha ndi kupangidwa pamwamba

Kutembenuzira kusuntha: Podula, chogwirira ntchito ndi chidacho ziyenera kudulidwa kuti zichotse zitsulo zochulukirapo. Kusuntha kwachitsulo chowonjezera pa chogwirira ntchito ndi chida chotembenuza pa lathe kumatchedwa kutembenuka, komwe kungagawidwe kukhala kayendetsedwe kake ndi kupita patsogolo. Perekani masewera olimbitsa thupi.

Kuyenda kwa chakudya: Gawo latsopano lodulira limayikidwa mosalekeza. Kuyenda kudyetsa ndikuyenda pamwamba pa workpiece kuti ipangidwe, yomwe ingakhale yopitilira kapena yapakatikati. Mwachitsanzo, lathe yopingasa imayenda mosalekeza pakuyenda kwa chida chotembenuza, ndipo kusuntha kwa chogwiritsira ntchito pa chowongolera mutu kumakhala kwapang'onopang'ono.

Kumwamba komwe kumapangidwira pa workpiece: Panthawi yodula, malo opangidwa ndi makina, makina opangidwa ndi makina, ndi malo oti apangidwe amapangidwa pa workpiece. Malo opangidwa ndi makina ndi malo atsopano omwe apangidwa kuchokera ku kuchotsa zitsulo zambiri. Malo oti akonzedwe amatanthauza pamwamba pomwe chitsulo chimadulidwa. Malo opangidwa ndi makina ndi malo omwe mbali yokhotakhota ya chida chotembenuzira imatembenuzidwa.CNC Machining gawo

Main zoyenda: mwachindunji kudula wosanjikiza pa workpiece ndi kusandutsa tchipisi, motero kupanga mayendedwe a padziko latsopano workpiece, amatchedwa chachikulu zoyenda. Podula, kusuntha kozungulira kwa workpiece ndiko kuyenda kwakukulu. Kawirikawiri, kuthamanga kwa kayendetsedwe kake kumakhala kokwera kwambiri, ndipo mphamvu yodula yomwe imagwiritsidwa ntchito ndi yofunika kwambiri.Kusintha kwa mtengo wa CNC

 
Chachiwiri, kuchuluka kwa malo opangira makina kumatanthawuza kuzama kwakuya, kuchuluka kwa chakudya, komanso kuthamanga.

(1) Kudula kwakuya: ap = (dw - dm) / 2 (mm) dw = m'mimba mwake mwa chogwiritsira ntchito chosagwiritsidwa ntchito dm = m'mimba mwake mwa makina opangidwa ndi makina, kuya kwa kudula ndizomwe timatcha kuchuluka kwa mpeni.

Kusankhidwa kwa kuya kwa kudula: Kuzama kwa αp kuyenera kutsimikiziridwa molingana ndi chilolezo cha makina. Pamene roughing, kupatulapo otsala allowance, roughing allowance ayenera kudulidwa momwe angathere. Izi sizingatsimikizire kokha kudulidwa kwakuya, kuchuluka kwa chakudya ƒ, ndi kudula liwiro V lalikulu pansi pamalingaliro owonetsetsa kukhazikika, komanso kumachepetsa kuchuluka kwa ma pass, ndikufuna kuphunzira UG manambala kuwongolera mapulogalamu mu QQ. gulu 304214709 akhoza kulandira deta. Pankhani ya kuchuluka kwa machining allowance, kusakhazikika kwadongosolo kwadongosolo, kapena mphamvu ya tsamba losakwanira, iyenera kugawidwa m'magawo awiri kapena kuposerapo. Panthawiyi, kudula kuya kwa chiphaso choyamba kuyenera kutengedwa mokulirapo, komwe kumatha kuwerengera 2/3 mpaka 3/4 ya chiwongola dzanja chonse, ndipo kuzama kwa chiphaso chachiwiri kuyenera kukhala kocheperako kuti mupeze njira yomaliza - yaying'ono. pamwamba roughness parameter values ​​ndi apamwamba Machining kulondola.

Pamwamba pa gawo lodulirapo pamakhala zinthu zolimba zolimba monga zitsulo zotayidwa, zopukutira, kapena zosapanga dzimbiri, kuzama kwa kudula kuyenera kupitilira kulimba kapena kuzizira kuti musadulire mphepete mwazovuta kapena kuzizira.

(2) Kusankhidwa kwa kuchuluka kwa chakudya: kusamutsidwa kwachibale kwa workpiece ndi chida cholozera kusuntha kwa chakudya, m'mayunitsi a mamilimita pakusintha kapena kubwezeretsanso kwa workpiece kapena chida. Pambuyo pakusankhidwa kwa kuya kwa kudula, chakudya chofunikira kwambiri chiyenera kusankhidwa momwe zingathere. Mtengo wokwanira wa chakudya uyenera kuwonetsetsa kuti makina ndi chida sichikuwonongeka ndi mphamvu yodula kwambiri. Kupotoka kwa workpiece chifukwa cha mphamvu yodulira sikudutsa mtengo wololeka wa workpiece molondola, ndipo pamwamba roughness parameter mtengo si waukulu kwambiri. Pamene roughing, malire a chakudya makamaka kudula mphamvu. Pamene theka-kumaliza ndi kutsiriza, malire a chakudya makamaka roughness pamwamba.

(3) Kusankhidwa kwa liwiro lodula: Kuthamanga kwanthawi yomweyo kwa mfundo pa chida chodulira chokhudzana ndi pamwamba kuti chipangidwe munjira yayikulu yosunthira panthawi yodula; unit ndi m/min. Pamene kudula kuya αp ndi kuchuluka kwa chakudya ƒ amasankhidwa, pazipita kudula liwiro amasankhidwa potengera ena, ndi njira chitukuko cha ndondomeko kudula ndi mkulu-liwiro Machining.

 

Chachitatu, roughness makina lingaliro

M'makaniko, kuuma kumatanthawuza mawonekedwe ang'onoang'ono a geometric, nsonga, ndi zigwa pamtunda wopangidwa ndi makina. Ndi limodzi mwamavuto a kafukufuku wosinthika. Ukali wapamtunda nthawi zambiri umapangidwa ndi njira zogwirira ntchito ndi zinthu zina, monga kukangana pakati pa chida ndi gawolo panthawi yokonza, mapindikidwe apulasitiki achitsulo chapamwamba pakulekanitsa kwa chip, komanso kugwedezeka kwapang'onopang'ono pamakina opangira. Chifukwa cha kusiyana pakati pa njira yopangira ndi zinthu za workpiece, pamwamba pake kuti apangidwe amasiya chizindikiro ndi kusiyana kwakuya, kachulukidwe, mawonekedwe, ndi mawonekedwe. Ukali wapamtunda umagwirizana kwambiri ndi mawonekedwe amakanika, kukana kuvala, mphamvu ya kutopa, kuuma kwa kukhudzana, kugwedezeka, ndi phokoso la magawo amakina. Zimakhudza kwambiri moyo wautumiki wamakina ndi kudalirika.

 

Chachinayi, kuyimira movutikira

Mbaliyo ikapangidwa, imaoneka yosalala komanso yosagwirizana. Kuuma kwapamtunda kumatanthawuza mawonekedwe a geometric ang'onoang'ono ang'onoang'ono ndi nsonga zing'onozing'ono ndi zigwa pamtunda wa gawo lopangidwa ndi makina, zomwe nthawi zambiri zimapangidwa ndi njira yopangira zinthu ndi zina zomwe zimatengedwa. Ntchito ya pamwamba pa gawoli ndi yosiyana, ndipo zofunikira zamtundu wa roughness parameter ndizosiyananso. Khodi ya roughness pamwamba imayikidwa pagawo lojambula kuti liwonetsere mawonekedwe a pamwamba omwe ayenera kukwaniritsidwa akamaliza pamwamba. Pali mitundu itatu ya kutalika kwa roughness:

1. Kufotokozera masamu kumatanthauza kupatuka Ra

Kutanthawuza masamu a mtunda wotheratu pakati pa mfundo yomwe ili pamzerewu motsatira njira yoyezera (Y mayendedwe) ndi mzere wolozera pautali wachitsanzo.

2, kusamvana kwakung'ono 10 mfundo kutalika Rz

Imatanthawuza kuchuluka kwa nsonga zisanu zotalikirapo zotalikirana kwambiri ndi avereji ya kuya kwachisanu kokulirapo kwa zigwa mkati mwa utali wa zitsanzo.

3, kutalika kwakukulu kwa contour Ry

Mtunda pakati pa mzere wapamwamba kwambiri ndi mzere wapansi wa mbiriyo pautali wa chitsanzo.

Ra. amagwiritsidwa ntchito makamaka m'makampani opanga makina.

 

Chachisanu, Zotsatira za roughness pa ntchito ya gawo

The pamwamba khalidwe pambuyo Machining workpiece mwachindunji zimakhudza workpiece thupi, mankhwala, ndi makina katundu. Ntchito yogwirira ntchito, kudalirika, ndi moyo wautumiki wa chogwirira ntchito zimadalira makamaka kumtunda kwa gawo lapakati. Nthawi zambiri, magawo ofunikira amtundu wamtundu wapamwamba amakhala apamwamba kuposa magawo wamba chifukwa magawo omwe ali ndi mawonekedwe abwino amawongolera kwambiri mavalidwe awo, dzimbiri, komanso kukana kutopa.
