摘要
采用当前方法设计的系统对数控铣床加工误差进行修正时,修正误差所用的时间较长,修正后的数控铣床加工误差仍较高,存在修正效率低和修正效果差的问题。提出基于模态分析的数控铣床加工误差修正系统设计方法,由数据采集模块、监测状态模块、信号分析模块、性能劣化分析模块、可靠性分析模块构成数控铣床加工误差修正系统的整体结构,对数控铣床进行模态分析,根据分析结果构建齿面方程,对触控铣床加工误差进行计算,构建数控铣床加工误差修正模型,实现数控铣床的加工误差修正。实验结果表明,所提方法的修正效率高、修正效果好。
When the system designed by the current method is used to correct the machining error of the CNC milling machine, it takes a long time to correct the error. The corrected machining error of the CNC milling machine is still high, which has the problems of low correction efficiency and poor correction effect. The design method of NC milling machine processing error correction system based on modal analysis is proposed. The data acquisition module, monitoring status module, signal analysis module, performance degradation analysis module, and reliability analysis module constitute the overall structure of the NC milling machine processing error correction system. The milling machine performs modal analysis, constructs the tooth surface equation according to the analysis results, calculates the machining error of the touch milling machine, constructs the machining error correction model of the CNC milling machine, and realizes the machining error correction of the CNC milling machine. Experimental results show that the proposed method has high correction efficiency and good correction effect.
