<p>A high-speed machining system for executing a machining program of a numerical control apparatus at high speeds. The numerical control apparatus incorporates a hard disc drive (20) that stores machining program for numerical control, a hard disc control circuit (15), a direct memory access control circuit (14) that transfers the machining program transferred from the hard disc control circuit (15) to a RAM (13), and a microprocessor (12). The direct memory access control circuit (14) transfers the machining program of the hard disc drive (20) to the RAM (13). The microprocessor (12) converts the machining program of RAM (13) into the amount of fine movement of each of the axes and transfers them to CNC (2). Therefore, the data can be transferred at high speeds, and the machining is carried out at high speeds with a simple construction.</p> |
