摘要
数控回转轴的补偿方法是采用激光检测软件生成补偿数据,将数据录入系统的齿距补偿表实现位置精度补偿。当补偿数据较多时,手工录入方式效率低,而且目前数控系统种类和型号繁多,调试人员容易出错。本文以Renishaw仪器和FANUC数控系统为例,引入自动补偿软件,将测试软件生产补偿数据翻译为数控系统可识别参数文件,并通过常用的USB传输方式导入到数控系统中,从而对其齿距误差进行有效补偿。该自动软件补偿方法,相比常规的人工输入方式既避免了调试人员由于系统差异导致的参数设置错误,又避免了手工输入数据错误产生的误差带来时间上的浪费,同时还可充分利用数控系统补偿参数表的最大螺补点数空间,使数控回转轴位置精度到达最佳补偿效果。
Error compensation method of CNC rotary axis is to equalize positional accuracy by inputting compensation data which is generated by laser interferometer analysis software into the pitch compensation table of control system. When there are lots of compensation data and heterogeneous CNC system,manual inputting method is inefficient and easy to make mistakes. Take the Renishaw laser interferometer and FANUC CNC system for example, by introducing new automatic error compensation software, compensation data which is generated by laser interferometer analysis software can be translated into readable parameter file of CNC system by using USB interface or device and equalize positional accuracy. The new software could avoid setting parameters failed of easily confused CNC system, wasting time for manual inputting error compensation data. At the same time, it could use the maximum space of CNC system pitch compensation parameter table, which helps CNC rotational axis to achieve the best positioning accuracy.
