Kodi ndalama ndi ndalama zotani?

Asanayambe kumaliza gawo, ntchito zambiri zimapangidwa ndi workpiece. Chimodzi mwa zofunika kwambiri ndikutengera ndalama zothandizira. Kukula kwake ndi kusiyana pakati pa kukula kwa workpiece ndi kukula kwa gawo molingana ndi kujambula. M'nkhaniyi, tiphunzira kuti malipiro ndi chiyani komanso momwe tingawerengere molondola.

Mitundu ya malipiro

Ndalamazo ndizitsulo zomwe zimachotsedwa pamwamba pa workpiece kuti zipeze gawo lomaliza. Izi ndizofunika kuti zitsimikizidwe kuti ziyeneretsozo ndi zofunikira komanso chikhalidwe chofunikira cha gawolo. Tapeza kale kuti ndalama ndi chiyani, ndipo tsopano tipeze kuti zilipo. Malinga ndi njira yopangira ziwalozo, malipiro akhoza kukhala pakati, othandizana ndi ena onse. Monga lamulo, omalizawa amawerengedwa powonjezerapo. Mphatso ikhoza kuwerengedwa ngati kukula kwake, ndi kumbali.

Kodi mtengo umadalira chiyani?

Takhala tidziwa kale kuti gawoli ndi liti, ndipo tsopano tikuphunzira kuchokera ku zinthu zomwe kukula kwake kumadalira. Choyamba, ndithudi, kuchokera kuzinthu zamakono za ubwino wa pamwamba ndi kulondola kwa workpiece. Kuwonjezera apo, kukula kwa ndalamazo kumadalira kusintha kwa gawo ndi miyeso yake. Chinthu china chofunika chomwe chimakhudza mtengo wosankhidwa ndi mtundu wa kupanga. Sitiyenera kuiwala za zolakwika pakuyika gawolo mu chipangizochi.

Kuwerengedwa kwa malipiro m'njira ziwiri

Tapeza kale kuti malipiro ndi chiyani komanso zomwe zimakhudza kukula kwake, ndipo tsopano tikuphunzira momwe tingawerengere molondola. Pali njira ziwiri: ziwerengero (zolemba) ndi zowerengera (zowerengedwa). Yoyamba imatsimikiziridwa ndi GOST zomwe zimagwirizana ndipo zimadalira mtundu wa workpiece ndi processing path. Choyamba, kuti muwerenge kukula kwa gawo lokonzekera ndi njira ya chiwerengero, nkofunikira kupanga njira yopangira ntchito yopangira ntchito. Kuwonjezera pamenepo, kulekerera kwa sayansi kwa kusintha kwa sayansi kumapatsidwa. Tsopano, malingana ndi matebulo, mphotho R _z ndi h imapatsidwa ndi ma GOST omwewo. Kuwonjezera pamenepo, m'pofunika kuwerengera mtengo wa zolakwika zonse zapakati. Ndalama zamakono zogwiritsidwa ntchito ndi njira ya mulingo ziyenera kuwerengedwera kuchokera kusintha kotsirizira, ndiko kuti, mu dongosolo la ndondomeko yowonongeka.

Mafupa otsatirawa amagwiritsidwa ntchito kuti awerengere ndalamazo mwa njira yowunika.

Pamalo ozungulira:

Malo okwera:

Kumeneko:

• R _z ndi mtengo wa microroughness;
• H ndi kuya kwake kosalala;
• Ρ _i-1 - mtengo wa zolakwika zonse zapakatikati;
• _I - zolakwika za ntchito yopanga ntchito;
• Ndalama ya ntchitoyi.

Malipiro apakati a machining (osachepera) amawerengedwa ndi molondola kwambiri - mpaka micrometer, ndipo kuzungulira kuyenera kupangidwa pamwamba.

Mosasamala kanthu za mtundu wanji wa malipiro omwe amawerengedwa, ziyeneranso kuganiziridwa kuti mtengo wake uyenera kupitirira kuperewera kwa chipangizo chaching'ono kuti chida chochekacho chichotsedwe mu ntchito yowerengedwera ntchito. Zoonadi, panthawi zosiyanasiyana komanso zosiyana siyana, mawonekedwe apamwambawa amasiyana pang'ono. Mwachitsanzo, njirayi imachotsa kutalika kwa gawo lopanda malire ndi malipiro ake (h _i-1 ) popera pogwiritsa ntchito chithandizo cha kutentha, popeza kuti makamaka pamtunduwu pamwamba pake pamayenera kusungidwa.
