2. Te awe o te tukanga whakarewa ki te kounga whakarewa
Te pānga o te ōwehenga kurupae-pūngao raupapa ki te hanganga hononga whakarewa
Ina 2kW te mana o te taiaho, ko te tere whakarewa he 45 mm/s, ko te nui o te whakakorenga arotahi he 0mm, ā, ko te tawhiti o te hihi he 3 mm, ko te āhua o te mata whakarewa ina huri te RS (RS= 0.50, 0.67, 1.50, 2.00) ka rite ki te mea e whakaaturia ana i te pikitia. Ina 0.50 me te 2.00 te RS, ka nui ake te pakaru o te whakarewa, ā, ka nui ake te tauhiuhi i te taha o te whakarewa, me te kore e hanga i ngā tauira unahi ika noa. Nā te mea he iti rawa, he nui rawa rānei te ōwehenga pūngao hihi, ka tino kukū te pūngao taiaho, ka nui ake te wiri o te kōhao taiaho i te wā o te tukanga whakarewa, ā, ka puta te pēhanga hoki o te mamaoa ki te maka me te tauhiuhi o te konganuku puna rewa ki roto i te puna rewa; ka nui rawa te hohonutanga o te urunga o te puna rewa i te taha koranu konumohe, ka puta he hekenga i raro i te mahi a te kaha ā-papa. Ina ko te RS=0.67 me te 1.50, he ōrite te tauira unahi ika i runga i te mata whakarewa, he ātaahua ake te āhua whakarewa, ā, kāore he kapiti wera whakarewa e kitea ana, he pūwero me ētahi atu hapa whakarewa i runga i te mata whakarewa. Ko ngā āhua whakawhiti-wāhanga o ngā whakarewa me ngā ōwehenga pūngao hihi rerekē RS e whakaaturia ana i te pikitia. Ko te whakawhiti-wāhanga o ngā whakarewa he "āhua karāhe waina" noa, e tohu ana kei te whakahaerehia te tukanga whakarewa i roto i te aratau whakarewa urunga hohonu laser. He pānga nui a RS ki te hohonutanga urunga P2 o te whakarewa i te taha konumohe. Ina ko te ōwehenga pūngao hihi RS=0.5, ko te P2 he 1203.2 maikorona. Ina ko te ōwehenga pūngao hihi RS=0.67 me te 1.5, ka tino heke te P2, arā, 403.3 maikorona me te 93.6 maikorona. Ina ko te ōwehenga pūngao hihi RS=2, ko te hohonutanga urunga o te whakawhiti hononga he 1151.6 maikorona.
Te pānga o te ōwehenga kurupae-pūngao whakarara ki te hanganga hononga whakarewa
Ina he 2.8kW te mana o te taiaho, ko te tere whakarewa he 33mm/s, ko te nui o te whakakore arotahi he 0mm, ā, ko te tawhiti o te hihi he 1mm, ka whiwhihia te mata whakarewa mā te whakarerekē i te ōwehenga pūngao hihi (RS=0.25, 0.5, 0.67, 1.5, 2, 4). Ka whakaaturia te āhua i roto i te pikitia. Ina he 2 te RS, he āhua koretake te tauira unahi ika i runga i te mata o te whakarewa. He pai te hanganga o te mata o te whakarewa i whiwhihia e ngā ōwehenga pūngao hihi rerekē e rima, ā, kāore he hapa e kitea ana pērā i ngā pore me te ruirui. Nō reira, ki te whakataurite ki te hihi-rua raupapawhakarewa laser, he ōrite ake, he ātaahua ake te mata whakarewa mā te whakamahi i ngā kurupae-rua whakarara. Ina RS=0.25, he iti te hekenga o te whakarewa; i te piki haere o te ōwehenga pūngao kurupae (RS=0.5, 0.67 me te 1.5), he ōrite te mata o te whakarewa, ā, kāore he hekenga e puta; heoi, ina piki haere tonu te ōwehenga pūngao kurupae (RS=1.50, 2.00), engari he hekenga kei runga i te mata o te whakarewa. Ina RS=0.25, 1.5 me te 2 te ōwehenga pūngao kurupae, ko te āhua whakawhiti-wāhanga o te whakarewa he "āhua karāhe waina"; ina RS=0.50, 0.67 me te 1, ko te āhua whakawhiti-wāhanga o te whakarewa he "āhua kōrere". Ina RS=4, ehara i te mea ko ngā kapiti anake ka puta i te raro o te whakarewa, engari ka puta hoki ētahi pūwero i te wāhanga waenga me raro o te whakarewa. Ina RS=2, ka puta ngā pūwero tukanga nui i roto i te whakarewa, engari kāore he kapiti e puta. Ina ko te RS=0.5, 0.67 me te 1.5, ka iti ake te hohonutanga o te urunga P2 o te whakarewa i te taha konumohe, ā, he pai te āhua o te wāhanga whakawhiti o te whakarewa, ā, kāore he hapa whakarewa e kitea ana. E whakaatu ana ēnei he pānga nui anō hoki te ōwehenga pūngao hihi i te wā e whakarewahia ana te taiaho hihi-rua whakarara ki te urunga whakarewa me ngā hapa whakarewa.
Kurupae whakarara – te pānga o te mokowā kurupae ki te hanganga hononga whakarewa
Ina 2.8kW te mana o te taiaho, ko te tere whakarewa he 33mm/s, ko te nui o te whakakorenga arotahi he 0mm, ā, ko te ōwehenga pūngao hihi RS=0.67, whakarerekētia te mokowā hihi (d=0.5mm, 1mm, 1.5mm, 2mm) kia whiwhi ai i te āhua o te mata whakarewa e whakaaturia ana i te pikitia. Ina d=0.5mm, 1mm, 1.5mm, 2mm, he maeneene, he papatahi te mata o te whakarewa, ā, he ataahua te āhua; he rite, he ataahua te tauira unahi ika o te whakarewa, ā, kāore he pūwero e kitea ana, he kapiti me ētahi atu hapa. Nō reira, i raro i ngā āhuatanga mokowā hihi e whā, he pai te hanganga o te mata whakarewa. Hei tāpiri, ina d=2 mm, ka hangaia he whakarewa rerekē e rua, e whakaatu ana kāore e mahi ngā hihi taiaho whakarara e rua ki runga i te puna rewa, ā, kāore e taea te hanga i tētahi whakarewa ranu taiaho rua-hihi whai hua. Ina 0.5mm te tawhiti o te hihi, he "āhua rite ki te kōrere" te whakarewa, ko te hohonutanga o te urunga P2 o te whakarewa i te taha konumohe koranu he 712.9 maikorona, ā, kāore he kapiti, he pūwero me ētahi atu hapa i roto i te whakarewa. I te piki haere tonu o te tawhiti o te hihi, ka tino heke te hohonutanga o te urunga P2 o te whakarewa i te taha konumohe koranu. Ina 1 mm te tawhiti o te hihi, ko te hohonutanga o te urunga o te whakarewa i te taha konumohe koranu he 94.2 maikorona anake. I te piki haere tonu o te tawhiti o te hihi, kāore te whakarewa e hanga i te urunga whai hua i te taha konumohe koranu. Nō reira, ina 0.5mm te tawhiti o te hihi, ko te pānga whakakotahitanga hihi-rua te mea pai rawa atu. I te piki haere o te tawhiti o te hihi, ka tino heke te urunga wera whakarewa, ā, ka kino haere te pānga whakakotahitanga taiaho-rua.
Ko te rerekētanga o te āhua o te whakarewa i puta mai i te rerekētanga o te rere me te whakamatao o te puna rewa i te wā o te tukanga whakarewa. E kore e taea e te tikanga whakatauira tau anake te whakapai ake i te tātari ahotea o te puna rewa, engari ka whakaitihia hoki te utu whakamātautau. E whakaatu ana te pikitia i raro nei i ngā huringa o te puna rewa taha me te kurupae kotahi, ngā whakaritenga rerekē me te mokowā ira. Ko ngā whakatau matua ko: (1) I te wā o te kurupae kotahiwhakarewa laserI roto i te tukanga, ko te hohonutanga o te kōhao puna rewa te mea tino hohonu, ka puta he āhuatanga o te hinganga o te kōhao, he koretake te pakitara o te kōhao, ā, he koretake te tohatoha o te mara rere tata ki te pakitara kōhao; tata ki te mata o muri o te puna rewa he kaha te rerenga anō, ā, he rerenga anō ki runga i te raro o te puna rewa; he ōrite te tohatoha o te mara rere o te mata o te puna rewa, ā, he koretake te whānui o te puna rewa i te ahunga hohonu.
