I te ao o te hanga whakarewa, he mea tino nui te tika. Ahakoa kei te mahi koe me te mīhini whakarara pereti, me te mīhini mira mata rua rānei, he mea nui te mārama ki te tatau i te koki whakarara o te pereti kia tutuki ai ngā hua e hiahiatia ana. Ma tēnei tuhinga koe e ārahi i roto i te tukanga tatau i ngā koki whakarara, me te tūhura hoki i ngā āheinga o ngā mīhini mira mata i hangaia mō ngā taha tika.
Te Mārama ki ngā Koki Whakarara
Ko te koki piko e pā ana ki te koki i hangaia i waenganui i te taha o te pereti me te rārangi e poutū ana ki taua taha. He tukanga tino nui te piko i roto i te mahi whakarewa, inā koa i te wā e whakarite ana i ngā taha mō te whakarewa, te huihuinga rānei. Ka pā nui te koki o te piko ki te kaha me te kounga o te hononga whakamutunga.
Te Tātai i ngā Koki Whakarara
Hei tatau i te koki piko o te pereti, ka taea e koe te whakamahi i te tātai e whai ake nei:
Tāutuhia te Matotoru o te Pereti (T): Inehia te matotoru o te pereti e mahi ana koe.
Whakatauhia te Whānuitanga o te Tapatapahi e Hiahiatia ana (W): Whakatauhia te whānui o te tapatapahi e hiahiatia ana.
Whakamahia te Mahi Pānga: Ka taea te tatau i te koki piko (θ) mā te whakamahi i te mahi pānga:
[\tan(θ) = \frac{W}{T}]
Tātaihia te Koki: Hei kimi i te koki, whakamahia te mahi arctangent:
[θ = \arctan\left(\frac{W}{T}\right)]
Hei tauira, mēnā he pereti 10 mm te matotoru, ā, e hiahia ana koe kia 5 mm te whānui o te anga, ko te tataunga tēnei:
[θ = \arctan\left(\frac{5}{10}\right) = \arctan(0.5) \approx 26.57°]
He mea hanga motuhake ngā mīhini whakapiko pereti hei hanga i ngā piko tika ki ngā taha o ngā pereti. Ka taea e ēnei mīhini te whakahaere i ngā matotoru me ngā rauemi rerekē, ā, ka taea ai te whakamahi hei taputapu whai hua i roto i ngā toa hanga katoa. He maha ngā wā ka tae mai me ngā tautuhinga whakarerekētanga e taea ai e ngā kaiwhakahaere te whakatakoto i te koki piko e hiahiatia ana, kia rite ai te hanganga puta noa i ngā wahi maha.
Mō te hunga e hiahia ana ki te whakatutuki i ngā tapa tika me te tino tika, he kōwhiringa pai rawa atu ngā mīhini mira mata rua. Ka taea e ēnei mīhini te mira i ngā taha e rua o te pereti i te wā kotahi, ka nui ake te hua. He tino whai hua ēnei mō te whakarite i ngā taha mō te whakarewa, nā te mea ka taea e rātou te hanga i ngā taha ma, tika e piri pai ana tetahi ki tetahi.
Kua hangaia ngā mīhini mira taha hei whakarato i tētahi āhua maeneene ki ngā taha o ngā pereti. Ka taea te whakamahi hei tango i ngā pūwero, hei hanga i ngā porowhita, hei whakarite rānei i ngā taha mō te tukatuka atu. I te whakamahi i tētahi mīhini mira taha, he mea nui kia tika te whakatikatika o te mīhini kia tutuki ai te āhua taha e hiahiatia ana.
Whakamutunga
Ko te tatau i te koki piko o te pereti he pūkenga taketake i roto i te hanga whakarewa e pā tika ana ki te kounga o te hua whakamutunga. Mā te mārama ki te whanaungatanga i waenga i te matotoru o te pereti me te whānui piko, ka taea e ngā kaihanga te whakarite kia tika, kia whai hua hoki ā rātou tukanga piko. Mā te whakamahi i ngā taputapu matatau pēnei i ngā mīhini piko pereti me ngā mīhini mira mata rua ka taea te whakapai ake i te whai huatanga me te tika o te whakarite mata. Ahakoa he tohunga mohio koe, he tauhou rānei ki te mara, mā te mōhio ki ēnei tikanga ka tino whakapiki ake i ō pūkenga mahi whakarewa.
