Amagama athi “ukufa kwesitembu” kanye “ithuluzi lokunyathela” zivame ukusetshenziswa ngokufanayo, futhi izincazelo zazo zingahlukahluka kuye ngokuthi umongo.Nokho, ngomqondo wezobuchwepheshe, kunomehluko phakathi kwalokhu okubili:

Incazelo: Ukugxiviza kuyafa, okubuye kwaziwe ngokuthi “ukufa,” kungamathuluzi akhethekile noma isikhunta esisetshenziswa emsebenzini wensimbi ukusika, ukwakha, noma ukulolonga insimbi yeshidi noma ezinye izinto zibe izimo ezithile noma ukumiswa.
Umsebenzi: Ama-dies asetshenziselwa ukwenza imisebenzi ethile enqubweni yokugxiviza, njengokusika, ukugoba, ukudweba, noma ukwakha.Zenzelwe ukudala umumo othize noma ijometri kundaba.
Izibonelo: Ukufa okungenalutho, ukubhoboza kuyafa, ukubumba kuyafa, ukudweba kuyafa, futhi ukufa okuqhubekayo yizo zonke izinhlobo zokunyathela ziyafa.

Amathuluzi okugxiviza:
Incazelo: Amathuluzi okugxiviza yigama elibanzi elingahlanganisi ama-dies ngokwawo kuphela kodwa nezinye izingxenye ezihlukahlukene kanye nemishini esetshenziswa enqubweni yokugxiviza.
Izingxenye: Amathuluzi okugxiviza awahlanganisi ama-dies kuphela kodwa nama-punch, ama-die sets, imihlahlandlela, ama-feeder, nezinye izinto zokusebenza ezisekelayo ezakha lonke uhlelo olusetshenziselwa imisebenzi yokugxiviza.
Umsebenzi: Amathuluzi okugxiviza ahlanganisa yonke isistimu edingekayo ukuze kwenziwe imisebenzi yokugxiviza, kusukela ekuphatheni okubalulekile nokuphakelayo kuya ekukhishweni kwengxenye nokulawula ikhwalithi.
Ububanzi: Amathuluzi okugxiviza abhekisela kukho konke ukusethwa kwamathuluzi asetshenziswa ekugxivizeni, kuyilapho okuthi “stamping dies” kubhekiselwa kuzingxenye ezinesibopho sokubumba noma ukusika impahla.
Kafushane, “ukunyathela kuyafa” kubhekiselwa ngqo ezingxenyeni ezibhekele ukubumba noma ukusika izinto enqubweni yokugxiviza.“Amathuluzi okugxiviza” ahlanganisa lonke uhlelo, okuhlanganisa ukufa, izibhakela, izindlela zokuphakela, nezinye izingxenye ezisekelayo ezisetshenziselwa ukwenza umsebenzi wokunyathela.Yize amagama evamise ukusetshenziswa ngokushintshana engxoxweni evamile, ukuhlukaniswa kwezobuchwepheshe kulele kububanzi balokho okuhlanganiswe nethemu ngalinye ngaphakathi kwenqubo yokugxiviza.
