摘　　要：针对数控技术向高速度、高精度发展的需求,研究数控系统精度测试技术对实现微观分析、减小故障率、加快机床调试进程具有重要意义.介绍一种采用美国NI公司的DAQ系统开发构建的测试装置,综合运用了插补、拟合、滤波等信号处理技术,实现了对数控系统的插补精度、定位精度和刀补等的有效测试,对系统的加减速过程作了准确分析,具有开发周期短、成本低的特点.With the development of numeric control technology toward high speed,high accuracy,it＇s of a great importance to research the technology of CNC accuracy testing for analyzing CNC in microcosmic, reducing the fault rate, quickening the machine tool debugging process. And introduced a test device that using of the DAQ processing modules, With the comprehensive utilization of several kinds of technology, such as the interpolating, composing, filtering and so on, the set can bring all expected function to success in practical application. The device＇s exploit period is very short and its cost is especially cheap.
