Ko te mahi a te mekameka he mahi tahi a ngā āhuatanga maha hei whakatutuki i te kaha nekeneke mahi. Mēnā he nui rawa, he iti rawa rānei te kume ka puta he haruru nui. Nā, me pēhea te whakarite i te taputapu kume kia tutuki ai te kume tika?
He mārama ngā pānga o te whakatōtika i te mekameka taraiwa ki te whakapai ake i te pono o te mahi me te whakaroa i te roa o te mahi. Heoi, me mārama ko te nui rawa o te tōtika ka whakanui ake i te pēhanga motuhake ki te hononga, ka whakaiti hoki i te kaha tuku o te mekameka. Nō reira, me whakatōtika i roto i ngā āhuatanga e whai ake nei:
1. Ka roa te mekameka i muri i te pakaru me te haehae, kia tika ai te piko me te ngāwari o te kawenga taha.
2. Ina kore e taea te whakarite i te tawhiti waenga i waenga i ngā wira e rua, he uaua rānei ki te whakarite;
3. Ina teitei rawa te tawhiti o te pokapū o te porotiti (A>50P);
4. Ina whakaritea poutū;
5. Kawenga pāorooro, wiri, pānga;
6. Ko te koki takai o te pīrori me te ōwehenga tere nui me te pīrori iti he iti iho i te 120°. Ka whakahaerehia te kukū mekameka e te nui o te totohu: ko te iti rawa ko (0.01-0.015)A mō te whakaritenga poutū me te 0.02A mō te whakaritenga whakapae; ko te teitei rawa ko te 3 meneti mō te tuku whānui me te 2 meneti mō te tuku tika.
Tikanga whakapūmau mekameka:
1. Whakatikatikahia te tawhiti o te pokapū o te porotiti;
2. Whakamahia te porotiti whakatōtika mō te whakatōtika;
3. Whakamahia ngā roera whakatōtika mō te whakatōtika;
4. Whakamahia he pereti pēhanga rapa, he porotiti rapa rānei hei whakatōtō;
5. Te whakatītaha waipēhi. Ina whakatītahahia te taha piri, me whakatītaha ki te taha o roto o te taha piri hei whakaiti i te wiri; ina whakatītahahia te taha wetekina, ki te whakaarohia te whanaungatanga koki takai o te porotiti, me 4p te tītaha e tata ana ki te porotiti iti; ki te kiia kua kore te piko, me whakatītaha ki te 4p ki te porotiti nui, ki te wāhi rānei e piko rawa ana te taha wetekina.
