摘　　要：基于PC的数控系统成为开放式数控系统发展的必然趋势 ,其中PC加控制板卡的结构成为实际的开放式标准体系。本文采用FPGA器件实现了扩展DDA圆弧插补算法 ,在满足较高精度的情况下 ,具有较快的插补速度 ,而且容易与电机的运动控制部分很好的集成 ,制作成控制板卡 。The NC systems based on PC are taking trend in the development of open NC systems Generally, the structure of PC plus control cards becomes the standard open hierarchy The aim of this work is to implement the algorithm of extended DDA arc interpolation with FPGA, which provides high-speed interpolation in the relatively high precision circumstances This approach is easy to be integrated with the motion control components of the motors, and made into control cards Hence it could easily be adapted to the development of open NC systems based on PC plus control cards
