.He aha i whakamahia ai ngā taiaho mō te tapahi?
"LASER", he kupu whakarāpopoto mō te Light Amplification by Stimulated Emission of Radiation, e whakamahia whānuitia ana i ngā āhuatanga katoa o te ao. Ina whakamahia te laser ki te mīhini tapahi, ka puta he mīhini tapahi tere, he iti te parahanga, he iti ake ngā mea e pau ana, ā, he iti te rohe e pāngia ana e te wera. I taua wā anō, ka taea e te tere tahuritanga hiko o te mīhini tapahi laser te rua te teitei o te tere tahuritanga hiko o te mīhini tapahi waro hauhā, ā, ko te roa o te māramatanga o te laser muka he 1070 nanometer, nō reira he tere mimiti teitei ake, he pai ake i te tapahi i ngā pereti whakarewa angiangi. Nā ngā painga o te tapahi laser koinei te hangarau matua mō te tapahi whakarewa, e whakamahia whānuitia ana i roto i te umanga miihini me te hanga, ko te mea tino kitea ko te tapahi pepa whakarewa, te tapahi i roto i te mara motuka, me ētahi atu.
.Me pēhea te mahi a te kaitapahi laser?
I. Te Mātāpono Tukatuka Taiaho
Ka arotahi te hihi laser ki tētahi wāhi mārama he iti rawa te whānui (ko te whānui iti rawa pea he iti iho i te 0.1mm). I roto i te pane tapahi laser, ka haere tētahi hihi kaha-nui mā roto i tētahi karāhe motuhake, i tētahi whakaata piko rānei, ka pekepeke ki ngā ahunga rerekē, ā, ka mutu ka huihui ki runga i te mea whakarewa hei tapahi. I te wāhi kua tapahia e te pane tapahi laser, ka tere te rewa o te whakarewa, ka mimiti, ka mimiti, ka tae rānei ki tētahi pūwāhi mura. Ka mimiti te whakarewa hei hanga kōhao, kātahi ka rehuhia he hau tere-teitei mā roto i tētahi pūwero e hono tahi ana me te hihi. Mā te pēhanga kaha o tēnei hau, ka tangohia te whakarewa wai, ka hanga he āputa.
Ka whakamahia e ngā mīhini tapahi taiaho ngā whatu me te mana rorohiko tau (CNC) hei ārahi i te hihi, i te rauemi rānei, i tēnei taahiraa ka whakamahia he pūnaha whakahaere nekehanga hei whai i te waehere CNC, G rānei o te tauira hei tapahi ki runga i te rauemi, kia tutuki ai te tapahi i ngā tauira rerekē.
II. Ngā tikanga matua o te tukatuka taiaho
1) Te tapahi rewa taiaho
Ko te tapahi whakarewa taiaho he whakamahi i te kaha o te hihi taiaho hei whakamahana me te whakarewa i te rauemi whakarewa, kātahi ka rehuhia te hau kore-waikura kua pēhia (N2, Hau, me ētahi atu) mā roto i te pūwero coaxial me te hihi, ā, mā te pēhanga hau kaha ka tangohia te whakarewa wai hei hanga i te hononga tapahi.
Ko te tapahi rewa taiaho te mea e whakamahia nuitia ana hei tapahi i ngā rauemi kore-waikura, i ngā konganuku tauhohe rānei pērā i te maitai kore waikura, te titanium, te konumohe me ō rātou koranu.
2) Te tapahi hāora taiaho
He rite te kaupapa o te tapahi hāora laser ki te tapahi oxyacetylene. Ka whakamahia te laser hei pūtake whakamahana, ā, ko te hau hohe pērā i te hāora hei hau tapahi. I tētahi taha, ka tauhohe te hau e tukuna ana ki te konganuku, ka puta he nui te wera o te waikura. He nui tēnei wera hei whakarewa i te konganuku. I tētahi atu taha, ka pupuhihia ngā waikura rewa me te konganuku rewa i waho o te rohe tauhohenga, ka puta he tapahi i roto i te konganuku.
Ko te tapahi hāora taiaho te mea e whakamahia ana mō ngā rauemi konganuku ngāwari te waikura pērā i te maitai waro. Ka taea hoki te whakamahi mō te tukatuka i te maitai kore waikura me ētahi atu rauemi, engari he pango, he taratara te wāhanga, ā, he iti iho te utu i te tapahi hau kore mahi.
