Abstract
A high-speed machining system for executing a machining program for a numerical control apparatus at high speed, in which the numerical control apparatus incorporates a hard disk drive (20) for storing a machining program for numerical control, a hard disk control circuit (15), a direct memory access control circuit (14) for transferring the machining program from the hard disk control circuit (15) to a RAM (13), and a microprocessor (12). The microprocessor (12) converts the machining program stored in the RAM (13) into minute amounts of movement for each axis and transfers the resulting data to a numerical control apparatus CNC 2. Therefore, a high-speed data transfer is possible and high-speed machining can be performed with a simple structure.
Claims2
