Xa inkqubo ye-CNC yenziwe yasebenza, ukusikwa okufunekayo kucwangciswe kwisoftware kwaye kuyalelwe kwizixhobo ezihambelanayo kunye noomatshini, abaqhuba imisebenzi yobukhulu njengoko kuchaziwe, kufana nerobhothi.

Kwinkqubo ye-CNC, i-code generator ngaphakathi kwenkqubo yamanani iya kuhlala icinga ukuba iindlela azinasiphako, ngaphandle kweempazamo ezinokwenzeka, ezinkulu nanini na xa umatshini we-CNC uyalelwe ukuba usike kwicala elinye ngaxeshanye.Ukubekwa kwesixhobo kwinkqubo yolawulo lwamanani kuchazwe luluhlu lwamagalelo aziwa ngokuba yinkqubo yenxalenye.

Ngomatshini wokulawula amanani, iinkqubo zifakwa nge-punch cards.Ngokwahlukileyo, iinkqubo zoomatshini be-CNC zondliwa kwiikhompyuter ngeekhibhodi ezincinci.Inkqubo ye-CNC igcinwa kwimemori yekhompyutha.Ikhowudi ngokwayo ibhaliwe kwaye ihlelwe ngabaprogram.Ke ngoko, iisistim ze-CNC zibonelela ngomthamo omkhulu wokubala.Okona kulungileyo, iisistim ze-CNC azimi nakancinane kuba iimpembelelo ezintsha zinokongezwa kwiinkqubo esele zikhona ngekhowudi ehlaziyiweyo.
