【摘要】：近年来数控机床发展迅速,数控机床的发展和研究已经成为能够推动工业化进程的重要因素,为了使数控机床更有效地应用于生产实践中,尚需对数字控制部分的实际误差和校正反馈进行深入研究,以提高工业精度及工作效率。本文通过对实验室自主研制的四轴雕刻数控机床进行研究,围绕数字控制和电机的优化展开误差分析,建立系统的误差模型,通过对误差的检测与校正,实现高精度和高效率的雕刻。同时对于四轴数控机床(CNC)中直线传动的三个轴使用直线电机进行传动,电机的类型进行选取和设计参数,对于雕刻精度和运行速度的提升进行研究,并对数字控制进行研究讨论。最后对于数控机床的实际操作即雕刻精度进行算法优化设计,采用误差反馈法进行计算,对雕刻刀的实际位置与数字位置进行对比校正。
[Abstract]:In recent years, with the rapid development of NC machine tools, the development and research of CNC machine tools have become an important factor that can promote the process of industrialization. In order to make CNC machine tools more effectively applied in production practice, it is necessary to deeply study the actual error and correction feedback of digital control parts in order to improve industrial accuracy and working efficiency. In this paper, through the research of the four-axis engraving CNC machine tool independently developed by the laboratory, the error analysis is carried out around the digital control and the optimization of the motor, and the error model of the system is established. Through the detection and correction of the error, the engraving with high precision and high efficiency can be realized. At the same time, the three shafts of linear transmission in four-axis NC machine tool (CNC) are driven by linear motor, the type of motor is selected and the design parameters are selected, the improvement of engraving accuracy and running speed is studied, and the digital control is studied and discussed. Finally, the algorithm optimization design of the actual operation of CNC machine tool, that is, the engraving accuracy, is carried out, and the error feedback method is used to calculate, and the actual position and digital position of the engraving tool are compared and corrected.
