Ukukhetha igrit yensimbi efanele kuyisihluthulelo sokuqinisekisa umphumela wokuhlanza weumshini wokudubula. Nazi ezinye izinyathelo nokucatshangelwa:
1. Izinto ezisetshenziswayo kanye nezidingo zokuhlanza: Okokuqala, thola izinto ezizohlanzwa kanye nezidingo zokuhlanza. Ama-workpieces ahlukene kanye nezidingo zingadinga izinhlobo ezahlukene zegrit yensimbi. Isibonelo, ukudubula kwensimbi kulungele ukuhlanza izindawo zensimbi, kuyilapho ubuhlalu bengilazi bufanele ukuhlanza okukhanyayo kanye nezinto zokusebenza ezinezidingo eziphezulu zokuqeda.
2. Izinto zensimbi yensimbi: Izinhlayiya zensimbi ezihlukene zinobunzima obuhlukile, ukwakheka nezici zokuhlanza. Isibonelo, isibhamu sensimbi sinekhono eliphezulu lokuhlanza nokuqina.
4. Iseluleko sabahlinzeki: Xhumana nomhlinzeki womshini oqhumayo ukuze uthole izeluleko nemibono yabo. Ngokuvamile banesipiliyoni esicebile futhi banganikeza isiqondiso esiwusizo ngokusekelwe kucezu lokusebenza kanye nezidingo zokuhlanza.
5. Izindleko nomnotho: Cabangela izindleko nomnotho wemithombo yezindaba eqhumayo. Izintengo zamagrits ensimbi ahlukene zingase zehluke, ngakho-ke kuyadingeka ukucubungulisisa ibhalansi phakathi komphumela wokuhlanza kanye nezindleko.
