<p>A CPU card (11), a servo card (12) and a display card (13) are replaceably mounted on a CNC controller-printed circuit board (10) which is fixed to the reverse side of a liquid crystal display unit (21), and execute a CNC control function. Further, a Programmable Machine Control (14), a spindle interface circuit (15) and a memory means (16) are mounted on the printed circuit board (10). These elements are connected with a bus. This arrangements provide a small-sized and thin-type CNC controller. The CNC controller is connected to each of servo amplifiers (41, 42,....) for axes through a serial servo bus (30) consisting an optical fiber. <IMAGE></p> |
