Ko R angle yesquare chubhu inotsanangurwa sei muyero yenyika?

Iyo R angle muskweya chubhu ndiyo inoshandura arc panosangana ndege mbiri, iyo inowanzoita hafu yedhayamita yepakati mutsara weiyo curved arc R angle. Kukosha kweiyo curved arc R inowanzoita 1.5 ~ 2.0 nguva yedhayamita yepombi. Saizi yeR angle inotarwa zvichienderana nemadziro emadziro echubhu yeskweya. Iyo R angle yakakamurwa kuita yemukati R angle uye yekunze R angle. Iyo yemukati R inowanzo 1.5 ~ 2 nguva ukobvu hwemadziro. Square simbi machubhu ane akasiyana maR angles anogona zvakare kugadzirwa zvinoenderana nezvinodiwa nemushandisi.
Semuenzaniso, kune rectangular simbi pombi ine denderedzwa arc R, A=1.0MM, diagonal=1.15MM, unoziva sei kona yeR? Kana iri sikweya simbi pombi ine arc, nzira yekuverenga yakafanana here? Rectangle ine urefu hweA uye hupamhi hweB, diagonal yeC, uye radius yemakona mana arcs R yakaenzana. Verenga saizi yeR nenzira inotevera: (C/2-R) ^ 2=(A/2-R) ^ 2+(B/2-R) ^ 2 C ^ 2/4-CR+R ^ 2 =A ^ 2/4-AR+R ^ 2+B ^ 2/4-BR+R ^ 2 4R ^ 2-4 (A+BC) R+(A ^ 2+B ^ 2-C ^ 2)=0.
Inofanira kusimbiswa pano kuti R angle yezasi rectangular chubhu hairevi kune arc, asi iyo yepakati angle. Iyo arc inoreva chikamu pane denderedzwa, uye iyo inosanganisirwa kona yemutsara pakati pemigumo miviri yearc uye pakati ndiyo yepakati angle. Sezvo denderedzwa redenderedzwa riri 2 π R uye kona yepakati inofambirana iri 2 π, kureba kwearc kunoenderana nechikamu chepakati angle i2 π R/2 π=R. Naizvozvo, kureba kwearc kunoenderana nechero kona yepakati a (radian unit) = aR inowanikwa. Nzira dzekuyera uye maturusi eskweya chubhu R kona anosanganisira R geji uye purojekita. Iyo R geji inogona kushandiswa kune gobvu mapoinzi, purojekita yemapoinzi akanaka, uye CMM yezvakakwirira zvinodiwa.
