2.3.4 CNC Machining chida njira chithunzi
Mu makina a CNC, nthawi zambiri pamafunika kutchera khutu ndikuletsa chidacho kuti chitha kugundana mwangozi ndi chojambula kapena chogwirira ntchito pakuyenda. Pazifukwa izi, ndikofunikira kuyesa kuwuza wogwiritsa ntchito za njira yoyendetsera zida mu pulogalamuyo (monga komwe mungadulire, komwe mungakweze chida, komwe mungadulire mosasamala, ndi zina). Kuti muchepetse chithunzi cha njira yazida, nthawi zambiri ndizotheka kugwiritsa ntchito zizindikiro zogwirizana kuti ziwonetsere. Zida zamakina zosiyanasiyana zimatha kugwiritsa ntchito nthano ndi mawonekedwe osiyanasiyana. Table 2.5 ndi mawonekedwe omwe amagwiritsidwa ntchito kwambiri.

2.3.5 CNC chida khadi
Pa CNC Machining, zofunika zida ndi okhwima kwambiri. Nthawi zambiri, kutalika kwa chida ndi kutalika kwake ziyenera kusinthidwatu pa chida chokhazikitsa chida kunja kwa makina. Khadi la chida likuwonetsa nambala ya chida, kapangidwe ka zida, mawonekedwe a chogwirira cha mchira, nambala ya dzina la msonkhano, chitsanzo cha tsamba ndi zinthu, ndi zina zotere. Onani Table 2.6 kuti mumve zambiri.
Table 2.6 CNC chida khadi
Zida zamakina osiyanasiyana kapena zopangira zosiyanasiyana zingafunike mitundu yosiyanasiyana ya CNC kukonza mafayilo apadera aukadaulo. Pantchito, mawonekedwe a fayilo amatha kupangidwa molingana ndi momwe zinthu zilili.
