Ngā Mīhini CNC (Te Whakahaere Rorohiko Tauwhai) | Ngā Pokapū Whakairoiro CNC Teitei Uara

Ko te Rorohiko Tauwhai (CNC) te hangarau whānui e mātai ana i te hanga tinihanga o nāianei, he punaha matatau kei reira ka uru atu tētahi rorohiko iti motuhake ki roto i tētahi taputapu tapahi kia arataki i ana mahi ki te pono me te hoki anō. Ko te matapuna o CNC he punaha mokowhiti-kati e hono ana i ngā waehanga tuatoru matua: te waehe whakahaere taputapu (MCU), te punaha taraiwa, me ngā kaiwhakaatu matatau. Ko te MCU, i runga reira he rorohiko ahumahi, ko ia te poukura. Ka pānui ia i ngā kaupapa rāwekenga—ngā tukutuku o ngā waehenga reta- tau (G-code me M-code) i hangaia mai i te pūnaha CAD/CAM—ka huri ai i ēnei ki ngā tohu irahiko. Ka whakahaua e ēnei tohu te punaha taraiwa, e whai mātātoko ana ngā motuka servomotor me ngā torikawa pōro, kia neke ngā tapa o te taputapu ki te pono tino. He mea nui, ko te punaha he "mokowhiti-kati," arā, ko ngā kaiwhakaatu rotary, i te pito rānei o ngā ine poto, e mataara tonu ana i te tūranga me te tere ake o te tapa me te taonga mahi, ka hoki i ēnei mōhio ki te MCU. Ka whakarārangihia tēnei mōhio takirua-takirua e te rorohiko ki te tūranga kua whakahaua, ka whakatika marino, mā te haerenga tonu kia wehe i te āhua rerekē. Ko te mokowhiti hoki tēnei e āwhina ai i ngā taputapu CNC kia eke ki te pono o ngā mikirone. Anō atu i te whakahaere mōhiotia noa, ka whakahaere te punaha CNC i ngā āhuatanga katoa o te tikanga tapahi: ka whakahaere i te tere me te torque o te spindle, ka whakahaere i te rere o te wai mātai, ka whakatinana i ngā panoni taputapu aunoa, ā, ka mataara hoki mō ngā raruraru e taea ana pērā i te popotangia o te taputapu, i te uaua hoki. Ko ngā punaha CNC hou anō hoki te karuwhenua ki te Ahumahi 4.0, e whai tauritenga ipurangi ana hei whakawhiti i ngā kaupapa (DNC), hei kohi i ngā mōhio taputapu mō te tātai mōhio, ā, e taea hoki te mataara, te whakawhitinga rānei i tētahi takiwā. Tēnei tuanui matihiko e āwhina ana i te hanga i ngā āhua tino matatau, mai i ngā āhua 2D noa ake ki ngā āhua 3D matatau, ki tētahi haora nui o ngā matapae. I te mutunga, ko CNC ehara i te noho kotahi anō i te whakahaere; ko ia te matihiko o te hanga tinana, e huri ana i tētahi hoahoa matihiko ki tētahi waehe tinihanga tino pono mā te tino tūhonohono, tētahi tikanga rorohiko-whakahaere e tiwha ana i te tautonotono, te maroke, me te kounga e kore e eke ana mā tētahi tikanga ā-ringa.
