Umgomo wokukhishwa wombhobho wefeni ocashuniwe uhlukile kunalowo wombhobho wefeni oyisicaba okhiphe i-axially. Isimo sokukhishwa kombhobho we-axial flat fan sakhiwa ngoba uketshezi luyakhishwa ngemuva kokukhanywa ukuze wakhe isimo sokukhishwa kwesiphephethi. Umbhobho weflethi ophambukayo ngokuvamile usho ukuthi uketshezi ludlula emgodini oyindilinga bese lushaya indawo yokuphambukisa. Idizayini yale ndawo yokuphambukisa ibaluleke kakhulu, futhi ibamba iqhaza elibalulekile empumelelweni yendiza. Ngokuvamile, kukhona i-tangent kumbhobho. I-arc yakhiwa ngokungeza umugqa oqondile.

Okungenhla kunombhobho obanzi we-angle ohlangothini olubanzi, futhi kukhona nombhobho wombhobho we-flat-angle. Umgomo wayo wokusebenza ngokuyisisekelo uyefana nowe-angle ebanzi.
