Ko ngā rauemi whakarewa e whakamahia whānuitia ana mō ngā wāhanga taputapu ko te kowiri tira, te parahi, te konumohe, te konutea, te koranu konupora, te maitai, te rino, me ētahi atu.
E ai ki ngā tikanga tukatuka rerekē, ka wehea ngā hua taputapu ki te tukatuka makariri me te tukatuka wera, ā, he rerekē anō hoki ngā momo tikanga hanga whakarewa. Ko ngā rauemi tukatuka makariri pēnei i te pepa whakarewa ka hangaia mā te tā matao mate, te piko, te kukume hōhonu me ētahi atu tukanga. Ko ngā wāhanga mahi wera, pēnei i ngā wāhanga whakarewa, ka hangaia mā te whakarewa i ngā rauemi mata taputapu ki te wai me te whakarewa ki ngā pokepokea.
Ko te whakapono whānui ko ngā rauemi pepa whakarewa katoa he rite te matotoru ka kiia he pepa whakarewa. Ko ngā rauemi pepa whakarewa e whakamahia whānuitia ana ko te maitai kore waikura, te pereti maitai piauau, te pereti tine, te parahi, te konumohe, te rino, me ētahi atu.
❶ te kaupapa o te matotoru ōrite o te hua
He rauemi te pepa whakarewa he ōrite te matotoru, me aro atu ki tēnei i roto i te hoahoa hanganga, inā koa he maha ngā piko, he ngāwari noa iho te kore ōrite te matotoru.
❷ te kaupapa o te whakawhāiti ngāwari
Ka tukatukahia ngā hua pepa whakarewa mai i ngā pepa. I mua i te tukatuka, ka papatahi ngā rauemi mata. Nō reira, i te wā e hoahoa ana i ngā wāhanga pepa whakarewa, me taea e ngā piko me ngā papa whakarara katoa te whāriki i runga i te papa kotahi me te kore e pokanoa. Hei tauira, ko te hoahoa o ngā wāhanga pepa whakarewa e whakaaturia ana i te Pikitia 1-1 kāore e whakaaetia nā te mea ka pokanoa tetahi ki tetahi i muri i te whārikitanga.
❸ te kaupapa o te whiriwhiri i te matotoru o ngā wāhanga pepa whakarewa kia tika
Ko te matotoru o ngā wāhanga pepa whakarewa he rerekē i waenga i te 0.03 ki te 4.00mm, engari ki te nui ake te matotoru, ka uaua ake te tukatuka, ka nui ake te hiahia mō ngā taputapu tukatuka, ā, ka piki ake te tere o te hapa. Me whiriwhiri te matotoru kia rite ki te mahi tuturu o te hua. I runga i te whakaaro kia tutuki te kaha me te mahi, ko te angiangi te pai ake. Mō te nuinga o ngā hua, me whakahaere te matotoru o ngā wāhanga pepa whakarewa i raro i te 1.00mm.
❹ kia rite ki te mātāpono o te hangarau tukatuka
Me hanga ngā hua pepa whakarewa ki te hangarau tukatuka, ā, me ngāwari hoki te hanga. Kāore e taea te hanga i ngā hua kāore e hanga ki te hangarau tukatuka, arā, he hoahoa kore tohu.
