THE APPLICATION OF EMBEDDED TECHNOLOGY IN NC SYSTEM

摘要

The paper analyzes the inherent drawbacks of the traditional NC system based IPC, puts forward and then provides the embedded NC system with the architecture of ARM and DSP, in which the ARM takes charge of the G code input, compiling and interpretation, the simulation display, the user's interface and the network interface etc, while the DSP is mainly in charge of real-time tasks such as interpolation computation and path control. The paper also introduces the hardware and software design in detail. Experiments show that NC system built on the embedded technology can reduce the system hardware scale, facilitate application development, cut down the costs and promote the system's reliability and real-time performance.
