Umatshini wokugaya we-CNC ubhekisa ekucubunguleni ngentsimbi ngezixhobo zokugaya ze-CNC, umatshini wokugaya we-CNC yindlela yokuvelisa isinyithi apho ikhowudi yokuseta ilawula oomatshini ngexesha lenkqubo yokuvelisa. Iinkonzo zokugaya ze-TTM CNC zithatha iindlela zokwenza izinto ezingaphantsi, oko kuthetha ukuba izixhobo ziyasuswa kwinkqubo yokuvelisa, nto leyo echasene nokuveliswa kwezinto ezongezelelweyo (njengokuprinta kwe-3D). Iinkonzo zokugaya ze-TTM CNC zisebenzisa itekhnoloji yamva nje yokuvelisa ukubonelela ngemisebenzi yokugaya nokujika ukuqinisekisa iziphumo ezilungileyo zomatshini wokugaya ngokuchanekileyo.
