1. Njira zowonjezerera kutha kwa pamwamba
Amagawidwa m'mitundu iwiri: kuwonjezera njira zofananira ndikuwongolera ndikuwonjezera njira zofananira panjira yoyambira: kuwonjezera kupukuta, kupukuta, kupukuta, kupukuta ndi njira zina sizingangowonjezera kusalala komanso kuwongolera kulondola; Komanso, akupanga anagubuduza luso, pamodzi ndi zitsulo pulasitiki fluidity, likupezeka onse m'nyumba ndi mayiko, amene ndi wosiyana ndi chikhalidwe ozizira ntchito kuumitsa ndi anagubuduza. Itha kukulitsa roughness ndi milingo 2-3 ndikuwongolera magwiridwe antchito azinthu zonse.

① Moyenera kusankha kudula liwiro. Kudula liwiro V ndi chinthu chofunikira chomwe chimakhudza roughness pamwamba. Pamene pokonza zipangizo pulasitiki, monga sing'anga ndi otsika mpweya zitsulo, m'munsi kudula liwiro sachedwa mapangidwe mamba ndi burrs, pamene sing'anga liwiro ndi sachedwa mapangidwe Chip madipoziti, amene adzawonjezera roughness. Kupewa liwiro ili kumachepetsa roughness ya pamwamba. Choncho mosalekeza kulenga zinthu kusintha liwiro kudula wakhala malangizo ofunika kuwongolera mlingo wa luso.
② Sankhani moyenera kuchuluka kwa chakudya. Kukula kwa mlingo wa chakudya kumakhudza mwachindunji roughness pamwamba pa workpiece. Nthawi zambiri, kuchuluka kwa chakudya kumacheperako, kumakhala kowuma pang'ono, ndipo chogwirira ntchito chimakhala chosalala.
③ Sankhani moyenerera magawo a geometric a chida chodulira. Makona akutsogolo ndi kumbuyo. Kuchulukitsa mbali yakutsogolo kungachepetse kupindika ndi kukangana kwa zinthu panthawi yodula, komanso kuchepetsa kukana kwathunthu kwa kudula, komwe kumapindulitsa pakuchotsa chip. Pamene ngodya yapano ikukhazikika, kukula kwa ngodya yakumbuyo, kucheperachepera kwa utali wozungulira wa m'mphepete mwake, ndi tsamba lakuthwa; Komanso, akhoza kuchepetsa mikangano ndi extrusion pakati kumbuyo kudula pamwamba ndi pamwamba machined ndi kusintha pamwamba, amene ali opindulitsa kuchepetsa pamwamba roughness mtengo. Kuchulukitsa arc radius r nsonga ya chida kumatha kuchepetsa kuuma kwake; Kuchepetsanso mbali yachiwiri ya Kr ya chidacho kumathanso kuchepetsa kuuma kwake.
④ Sankhani chida choyenera. Zida zokhala ndi matenthedwe abwino amafuta ziyenera kusankhidwa kuti zitumize kutentha kwanthawi yake ndikuchepetsa kupindika kwa pulasitiki pamalo odulira. Kuonjezera apo, chida chodulira chiyenera kukhala ndi mankhwala abwino kuti ateteze kuyanjana pakati pa chida chodulira ndi zinthu zowonongeka. Kugwirizanako kukakhala kwakukulu, ndikosavuta kupanga tchipisi ndi mamba, zomwe zimapangitsa kuti pakhale nkhanza kwambiri. Ngati aloyi yolimba kapena zida za ceramic zidakutidwa pamwamba pake, filimu yoteteza makutidwe ndi okosijeni imapangidwa pamalo odulira panthawi yodulira, yomwe imatha kuchepetsa kugundana kwapakati pakati pake ndi makina opangidwa ndi makina, motero kumapangitsa kusalala kwa pamwamba.
⑤ Sinthani magwiridwe antchito a workpiece. Kulimba kwazinthu kumatsimikizira pulasitiki yake, ndipo ndi kulimba kwabwino, kuthekera kwa kupunduka kwa pulasitiki ndikokulirapo. Pa makina processing, pamwamba roughness wa mbali ukuwonjezeka.
⑥ Sankhani madzi odulira oyenera. Kusankhidwa koyenera kwa madzi odula kumatha kuchepetsa kwambiri roughness pamwamba. Kudula madzimadzi kumakhala ndi kuzizira, kudzoza, kuchotsa chip, ndi ntchito zoyeretsa. Ikhoza kuchepetsa kukangana pakati pa workpiece, chida, ndi chip, kunyamula kutentha kwakukulu, kuchepetsa kutentha kwa malo odulidwa, ndikuchotsa tchipisi tating'ono panthawi yake.
