我们在试制和改进光通量法光电跟踪线切割机的过程中,学习了兄弟单位的先进经验,分析了光通量法线切割机中存在的主要问题,从而重点在纠偏信号的选择与放大问题上进行了改革。改革后的方案经过调整、试切,证明此方案抗干扰能力很强、系统跟踪基本稳定,目前精度可以达到0.04毫米(最大半径与最小半径之差值)。 During the process of trial production and improvement of the flux tracking photoelectric cutting machine, we learned the advanced experience of our brothers and analyzed the main problems existing in the flux normal cutting machine, so we focused on the selection and amplification of the correction signal reform. After the reform program adjusted, trial cut, proof of this program is very strong anti-interference, the system basically stable tracking, the current accuracy can reach 0.04 mm (maximum radius and minimum radius of the difference).
