CNC Machining Center ayenera kuchita zinthu izi bwino kudula zitsulo

Choyamba, kutembenuka kusuntha ndi kupangidwa pamwamba

Kutembenuza mayendedwe: Podula, kuti muchotse chitsulo chowonjezera, chogwirira ntchito ndi chidacho chiyenera kudulidwa pokhudzana ndi wina ndi mzake. 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: Chosanjikiza chatsopanocho chimayikidwa mosalekeza mumayendedwe odulira. Kuyenda kudyetsa ndikuyenda pamwamba pa workpiece kuti ipangidwe, yomwe ingakhale yoyenda mosalekeza kapena kusuntha kwapakatikati. Mwachitsanzo, lathe yopingasa imayenda mosalekeza panthawi ya kusuntha kwa chida chotembenuza, ndipo kayendedwe ka chakudya cha workpiece pa mutu wokonza mutu ndikusuntha kwapakatikati.

Pamwamba popangidwa pa workpiece: Panthawi yodula, malo opangidwa ndi makina, makina opangidwa ndi makina opangidwa ndi makina opangidwa ndi makina amapangidwa pa workpiece. Malo opangidwa ndi makina ndi malo atsopano omwe apangidwa ndi kuchotsa zitsulo zambiri. Malo oti apangidwe amatanthauza malo omwe zitsulo ziyenera kudulidwa. 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 yaikulu.cnc kutembenuza gawo

 
Chachiwiri, kuchuluka kwa kudula pakati pa makina kumatanthawuza kuzama kwakuya, kuchuluka kwa chakudya komanso kuthamanga.cnc mphero gawo

(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, kudula liwiro V lalikulu pansi pamalingaliro owonetsetsa kukhazikika, komanso kungachepetse kuchuluka kwa ma pass, ndikufuna kuphunzira UG manambala kuwongolera mapulogalamu mu QQ gulu. 304214709 ikhoza kulandira deta. Pankhani ya kuchuluka kwa machining allove kapena kusakhazikika kwadongosolo kwadongosolo kapena mphamvu ya tsamba losakwanira, iyenera kugawidwa m'magawo awiri kapena kuposerapo. Panthawiyi, kudula kwakuya kwa chiphaso choyamba kuyenera kutengedwa mokulirapo, komwe kumatha kuwerengera 2/3 mpaka 3/4 ya ndalama zonse; ndi kudula kuya kwa chiphaso chachiwiri ndi chocheperako kuti mupeze njira yomaliza. Zing'onozing'ono pamwamba roughness parameter mfundo ndi apamwamba Machining kulondola.

Pamene pamwamba pa gawo lodula liri ndi zinthu zolimba zolimba monga zitsulo zotayidwa, zowonongeka kapena zosapanga dzimbiri, kuzama kwa kudula kuyenera kupitirira kuuma kapena kuzizira kosanjikiza kuti mupewe kudula m'mphepete mwachitsulo cholimba kapena chozizira.

(2) Kusankha kuchuluka kwa chakudya: kusamutsidwa kwachibale kwa workpiece ndi chida cholozera kusuntha kwa chakudya, mayunitsi a mm, pakusintha kapena kubwezerananso kwa workpiece kapena chida. Pambuyo pakusankhidwa kwa kuya kwa kudula, mlingo wokulirapo wa chakudya uyenera kusankhidwa momwe mungathere. Kusankhidwa kwa mtengo wokwanira wa chakudya choyenera kuonetsetsa kuti chida cha makina ndi chida sichikuwonongeka ndi mphamvu yodula kwambiri. Kupotoka kwa workpiece chifukwa cha mphamvu yodulira sikudutsa mtengo wololeka wa workpiece mwatsatanetsatane, 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 pamphepete mwa chida chokhudzana ndi pamwamba kuti chipangidwe mumayendedwe akuluakulu osunthira panthawi yodula, unit ndi m / min. Pamene kudula kuya αp ndi kuchuluka kwa chakudya ƒ amasankhidwa, pazipita kudula liwiro amasankhidwa pa maziko a ena, ndi njira chitukuko cha ndondomeko kudula ndi mkulu-liwiro Machining.

 

 

Chachitatu, roughness makina lingaliro

Mu zimango, roughness amatanthauza micro-geometric katundu wa phula ang'onoang'ono ndi nsonga ndi zigwa pa machined pamwamba. Ndi limodzi mwamavuto a kafukufuku wosinthika. Pamwamba pa roughness nthawi zambiri amapangidwa ndi njira processing ntchito ndi zinthu zina, monga kukangana pakati pa chida ndi pamwamba pa gawo pa processing, mapindikidwe pulasitiki wa pamwamba wosanjikiza zitsulo pa chip kulekana, ndi mkulu pafupipafupi kugwedera mu dongosolo ndondomeko. Chifukwa cha kusiyana pakati pa njira yopangira zinthu ndi zinthu za workpiece, pamwamba pazitsulo zomwe ziyenera kukonzedwa zimasiya chizindikiro ndi kusiyana kwakuya, kachulukidwe, mawonekedwe ndi mawonekedwe. Kuuma kwapamtunda kumagwirizana kwambiri ndi makina amakina, kukana kuvala, mphamvu ya kutopa, kuuma kwa kukhudzana, kugwedezeka ndi phokoso la magawo amakina, ndipo zimakhudza kwambiri moyo wautumiki komanso kudalirika kwazinthu zamakina.

 

 

Chachinai, kuyimira nkhanza

Pambuyo pa kupangidwa kwapamwamba kwa gawolo, kumawoneka bwino kwambiri ndipo kumakhala kosagwirizana poyang'ana. Kuuma kwa pamwamba kumatanthawuza mawonekedwe a geometric ang'onoang'ono ang'onoang'ono ndi nsonga zazing'ono ndi zigwa zomwe zili pamwamba pa gawo lopangidwa ndi makina, zomwe nthawi zambiri zimapangidwa ndi njira yokonza ndi/kapena zinthu 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 apamwamba omwe ayenera kukwaniritsidwa pambuyo pake. 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

Zimatanthawuza kuchuluka kwa nsonga zazikulu zisanu zazikulu kwambiri za nsonga zazikuluzikulu ndi avareji ya kuya kwa zigwa zazikulu zisanu 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.

Pakali pano, Ra. amagwiritsidwa ntchito makamaka m'makampani opanga makina.

 

 

Chachisanu, Zotsatira za roughness pa ntchito ya gawolo

The pamwamba khalidwe pambuyo Machining wa workpiece mwachindunji zimakhudza thupi, mankhwala ndi makina katundu workpiece. Ntchito yogwira ntchito, kudalirika ndi moyo wautumiki wa workpiece zimadalira kwambiri pamtundu wapamwamba wa gawo lalikulu. Nthawi zambiri, zofunikira zapamtunda zamagulu ofunikira kapena ofunikira ndizokwera kuposa zida wamba, chifukwa magawo omwe ali ndi mawonekedwe abwino amawongolera kwambiri kukana kwawo kuvala, kukana dzimbiri komanso kukana kutopa.
