Mtundu woyamba: mtundu wosinthira zomangira

Mtundu uwu wa ndodo yosinthira umalumikizidwa ndi chogwirira. Pozungulira chogwirira, chogwirira chimayendetsa chogwirira chosinthira mkati ndi kunja. Malo ozungulira a chogwirira amakankhira pamwamba pa chogwirira chozungulira, zomwe zimapangitsa kuti chogwirira ndi ngodya ya phiri yokhazikika pa chogwiriracho zisunthe pansi.

Yogwiritsidwa ntchito: Yogwiritsidwa ntchito mosiyanasiyana ndipo imatha kusinthidwa molondola kwambiri.

Ubwino: Zimaphatikiza kulondola kwa kulemba ndi kulondola kwambiri, ndipo zimatha kukhutiritsa oyamba kumene ndi akatswiri.

Zoyipa: Mukasintha nsalu ya minofu, kuya kosiyanasiyana kwa singano munjira iliyonse kumakhudza mawonekedwe ofanana.

Mtundu wachiwiri: mtundu wa screw wa masika

Mtundu uwu umalowa ndi kutuluka pozungulira ndodo yosinthira yomangidwa mkati, ndikukanikiza pamwamba pa chotsetsereka kudzera pamwamba pa chotsetsereka, zomwe zimapangitsa kuti chotsetsereka ndi ngodya ya phiri yokhazikika pa chotsetsereka zisunthire pansi.

Zoyenera: Zogwiritsidwa ntchito zosiyanasiyana, zimatha kukwaniritsa zofunikira zapakati komanso zapamwamba.

Ubwino: Maonekedwe ake ndi abwino ndipo amatha kusinthidwa ndi mawu ndi tochi pogwiritsa ntchito kuwala kwapakati mpaka kwakukulu.

Zoyipa: Makina osinthira ali ndi zofunikira zambiri, kapena amafunika kugwiritsa ntchito chizindikiro choyimbira. Popeza si kapangidwe kogwirizana, sikelo ndi choyimbiracho zimazungulira padera, ndipo sikeloyo ndi yosavuta kusuntha, zomwe zimapangitsa kuti zilembozo zikhale zosalondola.

Mtundu wachitatu: kalembedwe ka Archimedean

Mu mtundu uwu, pozungulira chosinthira, liwiro lokhazikika limayendetsa pini pa chosinthira, zomwe zimapangitsa kuti chosinthira ndi ngodya ya phiri yokhazikika pa chosinthira zisunthire pansi.

Chifukwa cha kapangidwe kake, batani losinthira la Archimedean lili ndi kamvekedwe kakafupi, kotero kamvekedwe ka kayendedwe ka sikelo iliyonse ndi kakakulu, zomwe zimakhala zovuta ngati mukukumana ndi singano yaying'ono kapena nsalu yofunikira kwambiri yomwe imafunika kulondola mawaya 1-2. Kusintha.

Yogwiritsidwa ntchito: Kusintha mwachangu kolimba, koyenera kupanga ulusi wosakhudzidwa ndi nsalu, monga ulusi wa thonje.

Ubwino: wosavuta komanso wachangu, woyenera oyamba kumene ndipo safuna zofunikira zapamwamba pakusintha makina a masters.

Zoyipa: Kugunda kwafupikitsa kumakhala kovuta kusintha molondola, ndipo vuto la kukonza ndi lovuta kupanga ma stroke opanda kanthu. Kuchepetsa kuchuluka kwa kayendedwe ka stroke, monga kuchepetsa kuchuluka kwa ma stroke kufika pa mizere 100, kungapangitse sikelo iliyonse kukhala yolondola kufika pa mizere 3.3. Komabe, kufupikitsa kuchuluka kwa ma stroke kumachepetsanso kuchuluka kwa makina oyenera.

Mwachidule, mtundu uliwonse wa batani losinthira uli ndi zabwino ndi zovuta zake. Pali kusiyana kokha pakulondola kwa kupanga, zipangizo ndi mtundu pakati pa mtundu uliwonse. Mwachidule, palibe chabwino kapena choipa kwenikweni, koma chiyenera kutengera chanu. Kutengera zosowa zanu zopangira komanso momwe antchito alili, sankhani mtundu womwe ukukuyenererani.
