Ibikoresho byinzokaibiranga:
1. Itanga ibipimo binini byo kugabanya intera yatanzwe
2. Igikorwa cyiza kandi cyoroshye
3. Ntibishoboka ko uruziga rwinzoka rutwara inyo keretse niba hari ibintu byujujwe
Ihame ry'ibikoresho by'inzoka:
Ibice bibiri byibikoresho byinyo hamwe ninzoka yinyo ni perpendicular kuri mugenzi we; inyo irashobora gufatwa nka helix ifite iryinyo rimwe (umutwe umwe) cyangwa amenyo menshi (imitwe myinshi) yakomerekejwe na helix kuri silinderi, kandi ibikoresho byinyo ni nkibikoresho byoroheje, ariko amenyo yacyo akingira inyo. Mugihe cyo gusya, kuzunguruka kwinzoka bizatwara uruziga rwinzoka kuzunguruka mu menyo imwe (inyo imwe-imwe) cyangwa amenyo menshi (inyo nyinshi) y'imitwe y'inyo Z1 / umubare w'amenyo yinzoka yinyo Z2.
