ʻO ka CNC Machining e pili ana i ka mīkini metala me nā mea hana mīkini CNC, ʻo CNC machining kahi ala hana metala kahi e hoʻonohonoho ai i nā code e hoʻomalu i ka mīkini i ka wā o ka hana ʻana.Lawe nā lawelawe machining TTM CNC i nā ʻano hana subtractive fabrication, ʻo ia hoʻi, ua wehe ʻia nā mea ma ke kaʻina hana, ʻo ia ke kūʻē i ka hana hoʻohui (e like me ka paʻi 3D).Hoʻohana nā lawelawe mīkini TTM CNC i ka ʻenehana hana hou e hāʻawi i nā hana wili a me ka huli ʻana e hōʻoia i nā hopena maikaʻi no ka mīkini kiʻekiʻe.
