1. Ngā mahi kaha: atamai, whakarerekētanga, whakakā-weto.
2. Rahi iti: ko te rahi he tata ki te 35% noa iho o ngā hua rite.
3. Ngāwari ki te whakamahi: he pūtake hiko kotahi-wāhanga, he waea māmā; he hanganga porotaka taketake e piri ana kia māmā ake ai te tirotiro; kāore e hiahiatia he whakakī hinu, kāore e hiahiatia he tirotiro ā-wāhi, ātete wai, ātete waikura hoki, ka tāuta ki tētahi koki.
4. He rua ngā herenga o te taputapu tiaki, he tiaki wera rawa, he tiaki taumaha rawa hoki. Ko te roanga o te haere ko te 15 hēkona, 30 hēkona, 45 hēkona, me te 60 hēkona. Ā, he mahi ā-ringa anō hoki.
5. CNC Atamai: Ka whakamahia e te kōwae hanga-roto he maramara rorohiko matatau kotahi me te pūmanawa whakahaere atamai hei whiwhi tika i ngā tohu paerewa (4-20mA DC /1-5VDC) e puta mai ana i ngā rorohiko, i ngā taputapu ahumahi rānei, kia tutuki ai te whakahaere atamai me te tūnga tika o te whakatuwheratanga o te takirere.
