Njira yosankhira odulira mphero nthawi zambiri imaganizira zinthu zotsatirazi kuti musankhe

1, Njira yosankhira odulira mphero nthawi zambiri imaganizira zinthu zotsatirazi:

(1) Kapangidwe ka gawo (poganizira za mawonekedwe a ntchito): Mawonekedwe a ntchito nthawi zambiri amakhala athyathyathya, akuya, obowoka, ulusi, ndi zina zotero. Zida zomwe zimagwiritsidwa ntchito pa ma profiles osiyanasiyana a ntchito ndi zosiyana. Mwachitsanzo, chodulira fillet chimatha kupukuta malo ozungulira, koma osati malo ozungulira a ntchito ya ...
 
(2) Zipangizo: Ganizirani momwe zimagwirira ntchito, kupanga ma chip, kuuma kwake ndi zinthu zosakaniza. Opanga zida nthawi zambiri amagawa zipangizo kukhala chitsulo, chitsulo chosapanga dzimbiri, chitsulo chosungunuka, zitsulo zopanda chitsulo, zitsulo zazikulu, titaniyamu ndi zinthu zolimba.
 
(3) Mikhalidwe ya makina: Mikhalidwe ya makina imaphatikizapo kukhazikika kwa makina ogwirira ntchito a chipangizo cha makina, momwe chogwirira chida chimagwirira ntchito ndi zina zotero.
 
(4) Kukhazikika kwa makina, zida, ndi ntchito: Izi zimafuna kumvetsetsa mphamvu yomwe ilipo ya chida cha makina, mtundu wa spindle ndi specifications, zaka za chida cha makina, ndi zina zotero, ndi kutalika kwa chogwirira cha chida ndi momwe chimagwirira ntchito.
 
(4) Gulu lokonza ndi gulu laling'ono: Izi zikuphatikizapo kugaya mapewa, kugaya kwa plane, kugaya kwa profile, ndi zina zotero, zomwe ziyenera kuphatikizidwa ndi mawonekedwe a chida posankha chida.

2. Kusankha ngodya ya geometric ya chodulira mphero
 
(1) Kusankha ngodya yakutsogolo. Ngodya ya rake ya chodulira mphero iyenera kutsimikiziridwa malinga ndi zida za chida ndi ntchito. Nthawi zambiri pamakhala zotsatirapo pa mphero, kotero ndikofunikira kuonetsetsa kuti m'mphepete mwake muli ndi mphamvu zambiri. Kawirikawiri, ngodya ya rake ya chodulira mphero ndi yaying'ono kuposa ngodya ya rake ya chida chozungulira; chitsulo chothamanga kwambiri ndi chachikulu kuposa chida cha carbide cholimba; kuphatikiza apo, pogaya zipangizo zapulasitiki, chifukwa cha kusintha kwakukulu kwa kudula, ngodya yayikulu ya rake iyenera kugwiritsidwa ntchito; pogaya zipangizo zosweka, Ngodya ya rake iyenera kukhala yaying'ono; pogaya zipangizo zolimba komanso zolimba, ngodya yoipa ya rake ingagwiritsidwenso ntchito.
 
(2) Kusankha njira yolowera tsamba. Ngodya ya helix β ya bwalo lakunja la mphero yomaliza ndi chodulira chozungulira ndi njira yolowera tsamba λ s. Izi zimathandiza mano odulira kudula pang'onopang'ono kulowa ndi kutuluka mu workpiece, zomwe zimapangitsa kuti mphero ikhale yosalala. Kuchulukitsa β kumatha kuwonjezera ngodya yeniyeni ya rake, kunola m'mphepete mwake, ndikupangitsa kuti ma chips azitulutsa mosavuta. Kwa odulira mphero omwe ali ndi m'lifupi mwake wopapatiza, kuwonjezera ngodya ya helix β sikofunikira kwenikweni, kotero β=0 kapena mtengo wocheperako nthawi zambiri umatengedwa.
 
(3) Kusankha ngodya yaikulu yopotoza ndi ngodya yachiwiri yopotoza. Zotsatira za ngodya yolowera ya chodulira cha nkhope ndi momwe imakhudzira njira yopoza ndi zofanana ndi ngodya yolowera ya chida chozungulira potembenuza. Ma ngodya olowera omwe amagwiritsidwa ntchito kwambiri ndi 45°, 60°, 75°, ndi 90°. Kulimba kwa dongosolo la ndondomekoyi ndi kwabwino, ndipo mtengo wocheperako umagwiritsidwa ntchito; apo ayi, mtengo waukulu umagwiritsidwa ntchito, ndipo kusankha ngodya yolowera kukuwonetsedwa mu Gome 4-3. Ngodya yachiwiri yopotoza nthawi zambiri imakhala 5°～10°. Chodulira cha cylindrical chimakhala ndi m'mphepete waukulu wokha komanso wopanda m'mphepete wachiwiri wopotoza, kotero palibe ngodya yachiwiri yopotoza, ndipo ngodya yolowera ndi 90°.
