Poganizira zamtsogolo, kuphatikiza kwa AI kudzaneneratu kulephera kwa zida, ndikukonza bwino kupanga kwapamadzi. Kupanga zinthu zosakanikirana, kuphatikiza CNC ndi njira zowonjezera, kudzapanga zigawo zovuta za pansi pa nyanja.
Kukhazikika kwa zinthu zachilengedwe kumathandizira kukonza makina opangira zinthu zachilengedwe, pomwe makina odziyimira pawokha a CNC amathandizira kugwira ntchito maola 24 pa sabata pa zombo.
Kupita patsogolo kwa ma axis ambiri ndi IoT kudzathandiza kusintha kwa nthawi yeniyeni kwa zinthu zapamadzi zomwe zimasintha.
Kuyika magetsi m'zombo kudzafuna CNC kuti pakhale mabatire ndi ma mota amagetsi.Zochitika padziko lonse lapansi monga kutumiza zinthu paokha zidzadalira CNC kuti iphatikize masensa.
Kutsiliza
Kukonza makina a CNC ndikofunikira kwambiri pamakampani opanga zinthu za m'nyanja, kuphatikiza kulondola ndi kulimba mtima kuti athetse mavuto a m'nyanja. Pamene ukadaulo ukupita patsogolo, ukulonjeza nyanja zotetezeka komanso zobiriwira. Kulandira kupita patsogolo kumeneku kudzapititsa patsogolo gawoli, ndikutsimikizira kuti anthu ali ndi mgwirizano wokhalitsa ndi nyanja.
