Ndikofunikira kukulitsa luso la ntchito ndikuchepetsa mtengo wokonza kuti musankhe utuchi moyenerera.Kutsatira ndi zinthu zina zoganizira posankha utuchi:

1) Factor of processing of things.Mutha kusankha utuchi wapadera wa zinthu mwala, konkire kapena matailosi malinga ndi zinthu zosiyanasiyana processing.

2) Factor of physical dimension.Kusankha kukula ndi kalembedwe ka tsamba la macheka molingana ndi mtundu ndi mafotokozedwe a zida zodulira.Mwachitsanzo, kutalika kwa tsamba lozungulira kuyenera kukhala katatu kuposa chodulira. structural kalembedwe macheka tsamba malinga ndi requirrment wa Machining olondola .Kutanthauza kusankha yopapatiza-kagawo kapena motsatizana sawtooth macheka tsamba pamene yosalala kudula pamwamba chofunika kapena pokonza zowonda ndi zosalimba zakuthupi, m'malo mwake kusankha lonse-kagawo macheka tsamba. pamene yosalala kudula pamwamba sikofunikira kwenikweni kapena kudula zinthu zokhuthala.

3) Chomwe chimagwiritsa ntchito zida.Kuti mutsimikizire moyo wodulira, tsamba la macheka lovala liyenera kukhazikitsidwa pazida zamphamvu kwambiri.Kuti mutsimikizire kudula bwino, tsamba lakuthwa la macheka liyenera kukhazikitsidwa pazida zotsika mphamvu. Ndikwabwino kusankha tsamba la macheka lovala mukamagwiritsa ntchito chodulira kapena chocheka chocheperako, apo ayi sankhani chocheka chakuthwa cha chodula chatsopano kapena cholondola kwambiri.
