摘要
数控机床加工精度是衡量机床性能的关键指标.影响加工精度的误差源有多种,最显著的是几何误差与热误差,占据机床总误差的 60％～70％.误差补偿被认为是提高机床加工精度经济高效的手段,其中误差精确测量、误差模型的建立是进行误差补偿的基础和前提.针对数控机床综合误差的测量、建模、补偿过程进行归纳总结,分析测量工具、建模和补偿方案的优缺点,列举数控机床精度优化方面的问题,并探讨未来的研究方向.
Abstract
The machining accuracy of CNC machine tools is a key indicator to measure the performance of machine tools.There are various error sources affecting machining accuracy,and the most significant ones are geometric errors and thermal errors,accounting for 60％to 70％of the total error of machine tools.Error compensation is considered an effective and economical means to improve the ma-chining accuracy of machine tools.Accurate measurement of errors and the establishment of error models are the foundation and prereq-uisite for error compensation.The measurement,modeling,and compensation processes of comprehensive errors in CNC machine tools were summarized,the advantages and disadvantages of measurement tools,modeling,and compensation schemes were analyzed,some key issues in accuracy optimization of CNC machine tools were pointed out,and the future research directions were discussed.
