I ēnei rā, kāore e ranea te tango noa i te mata o ngā wāhanga pepa whakarewa. He maha ake ngā kaiwhakamahi e hiahia ana ki te tapahi i ngā taha o ngā wāhanga pepa whakarewa. Engari e mōhio ana koe ki te rahi o te whakaawhiwhi? Me pēhea te whakatau i te nui o te tapahi e tika ana?
Ko te whakautu kei runga i te kaupapa o te miro. Me tukatuka e te umanga tukatuka kaihoko ngā wāhanga pepa whakarewa kia rite ki ngā whakaritenga tuhi. I te nuinga o te wā, me tika ēnei whakaritenga, ā, kāore e taea te whakarerekē. Mena ka tohua i roto i te tuhi whakaputa me porowhita te miro, ka nui te pānga o te whakaritenga o te anga ki te utu o te mea mahi. Nō reira, ahakoa mō te kaihanga tonu, mō te umanga tukatuka rānei, he mea tino nui kia tika te whiriwhiri i te nui o te anga e tika ana.
Whakatutukihia ngā hiahia hei kaupapa matua, kia iti rawa te taea
Hei whakarite i te haumaru me te whai hua o te whakamahinga o ngā taputapu tukatuka o raro, me maeneene ngā wāhanga pepa whakarewa, ā, me kore he pūwero. Ko ēnei taputapu o raro ka taea te whakamahi hei mīhini pēhi kuaha, hei mīhini piko, hei mīhini whakataurite rānei. I mua i te piko, i te whakataurite rānei, ki te kore he pūwero te rauemi, kāore he take mō te whakaawhiwhi, nā te mea ko te pūwero kua ara ake te pakaru o te roera whakataurite. Pērā anō hoki mō ētahi atu taputapu pēnei i ngā taputapu huri me ngā taputapu mira. Nō reira, he pai ake ngā wāhanga kāore he pūwero mō te tukatuka i muri mai.
Hei karo i te rakuraku o ngā kaimahi, e whakaatu ana ngā wheako he 0.1mm noa iho te anga e hiahiatia ana hei whakarite i te haumaru. Ahakoa ngā karapu rapa, ngā ngongo hau, ngā taura rānei e pā pinepine ana ki ngā taha o ngā wāhanga pepa whakarewa, e kore e pakaru i ngā wāhanga pepa whakarewa he iti iho i te 0.1mm te whānuitanga porowhita.
Ina whakaarohia te paninga, ka uaua, ka kanorau hoki ngā āhuatanga whai mana. Ko te tuatahi ko te momo paninga (KTL, paura, peita mākū), te momo me te kounga o te paninga, kātahi ko ngā tawhā taputapu, pērā i te maimoatanga o mua, te wā whakamaroke, te pāmahana whakamaroke rānei, tae noa ki te whakatakotoranga whakamutunga o te hua. He mea nui ēnei āhuatanga, me te radius taha, ki te roa o te tiaki waikura. Nō reira, me whakatau te nui o te chamfer e tika ana mā te whakamātautau hei whakaroa i te wā tiaki waikura. Ko te tikanga, me noho tonu ngā āhuatanga whai mana katoa i roto i te whakamātautau.
Mā te anga iti rawa o te 0.5 mm ka whakaratohia he paninga pono
E ai ki te DIN EN ISO 9227:2017, ko te "whakamātautau rehu tote kūpapa NSS" te tikanga e whakamahia ana hei tikanga whakamātautau i te parenga waikura. Ka whakaarohia te tukanga waikura i roto i te wā. Hei tāpiri, ka taea te hanga i te wāhanga whakawhiti hei whakaatu i te huringa matotoru o te paninga, kia ine ai i te nui o te whakaawhiwhi o te tauira (ka taea te ine tāpiri mēnā e tika ana). Ka taea hoki e ēnei tauira te whakaatu mārama he pānga te āhua o te pūtoro ki te matotoru o te paninga. Mō te miro kore taurite, ka heke te matotoru o te paninga i te piko mōrahi. Nō reira, ka taea te whakatau ka taea te whiwhi i te pānga whakaawhiwhi taha pai me te pūtoro ōrite.
Ko te paerewa ka taea e tātou te whiwhi mai i tēnei (hei tauira, mō ngā hanganga maitai, mō ngā whare taiwhenua rānei) e hiahia ana kia 2.0mm, neke atu rānei te whānui o te porowhita taha o ētahi wāhanga pepa whakarewa. Heoi, ko te nuinga o ngā tono mahi e whakaatu ana ka taea te whiwhi piri pai o te paninga mena ka oti te porowhita 0.5mm ki ngā wāhanga pepa whakarewa. Nā te mea ka piki ake te nui o te chamfer me te utu taputapu ka puta mai i te pikinga o te whānui o te taha, me kimi e ngā kaiwhakamahi te nui o te porowhita tika kia pai ai te miihini pono me te whai hua. Arā: te whakatutuki i ngā hiahia, kia iti rawa te taea.
