基于高精度非球面测量的数据采集与处理系统研究

Study on Data Collection and Processing System of High-precision Aspheric Surface Measured

根据高精度非球面补偿加工的要求,提出一种高精度非球面测量及数据处理系统.系统基于工控PC机和Windows98操作系统,用VisualC++作为开发工具,完成了硬件设计、数据采集、数据处理和非球面测量误差的评价.通过实验得到测量系统的随机误差,验证了系统的可靠性.

According to the requirement of the high precision aspheric surface compensation manufacturing, a high precision measurement and data processing system was designed and regulated. It is based on industrial PC and Windows98 operating system. Using the development tool of Visual C++, system hardware design, data collection and processing, and measurement error evaluation of aspheric surface have been finished. In order to testify the reliability of measurement system, the random error of system is obtained by experiment.
