Kutembenuza ndi mtundu wa makina, njira yochotsera zinthu, yomwe imagwiritsidwa ntchito popanga magawo ozungulira podula zinthu zosafunikira.Kutembenuza kumafunikira makina otembenuza kapena lathe, chogwirira ntchito, chowongolera, ndi chida chodulira.Chogwirira ntchito ndi chidutswa cha zinthu zomwe zimapangidwira kale zomwe zimatetezedwa kuzitsulo, zomwe zimamangiriridwa pamakina otembenuza, ndikuloledwa kuzungulira mofulumira kwambiri.Chodulira nthawi zambiri chimakhala chida chodulira cha mfundo imodzi chomwe chimatetezedwanso pamakina, ngakhale kuti ntchito zina zimagwiritsa ntchito zida zamitundu yambiri.Chida chodulira chimadyetsa chogwirira ntchito chozungulira ndikudula zinthu ngati tchipisi tating'ono kuti tipange mawonekedwe omwe mukufuna.

Kutembenuza kumagwiritsidwa ntchito popanga zozungulira, nthawi zambiri axi-symmetric, mbali zomwe zimakhala ndi zinthu zambiri, monga mabowo, grooves, ulusi, tapers, masitepe osiyanasiyana, komanso malo ozungulira.Zigawo zomwe zimapangidwira potembenuza nthawi zambiri zimakhala ndi zigawo zomwe zimagwiritsidwa ntchito pang'onopang'ono, mwinamwake zojambulajambula, monga ma shaft opangidwa mwachizolowezi ndi zomangira.Kutembenuza kumagwiritsidwanso ntchito ngati njira yachiwiri kuwonjezera kapena kuwongolera mbali zomwe zidapangidwa pogwiritsa ntchito njira ina.Chifukwa cha kulolerana kwapamwamba komanso kumalizidwa kwapamwamba komwe kutembenuka kungapereke, ndikwabwino kuwonjezera mawonekedwe osinthika ku gawo lomwe mawonekedwe ake adapangidwa kale.

Kutembenuza kumatha kuchitidwa pazinthu zosiyanasiyana, kuphatikiza zitsulo zambiri ndi mapulasitiki.Zinthu zodziwika bwino zomwe zimagwiritsidwa ntchito potembenuza ndi izi:

•Aluminiyamu
•Mkuwa
•Magnesiamu
•Nickel
•Chitsulo
•Mapulasitiki a thermoset
• Titaniyamu
•Zinc
