摘　　要：文章为了能够使普通车床加工精度得到提高,利用数学模型的分析及实验对普通车削加工过程中刀具主、副偏对于被加工件表面质量影响进行了全面的分析,从而提出了基于回转刀架的三自由度车削加工方法和控制原理,并且利用建模软件实现数控车床回转刀架精准控制方法的建模及仿真。通过仿真结果表示,基于回转刀架的三自由度精密车削和控制能够提高复杂回转面表面的精度,降低误差,提高稳定性,还能够实现自适应复杂曲面动态变化,整体性比普通车削加工要优。In order to improve the machining accuracy of common lathe,this paper makes a comprehensive analysis of the influence of the tool's main and auxiliary deviation on the surface quality of the workpiece in the process of common turning by mathematical model analysis and experiment.Thus,the three-degree-of-freedom turning meth⁃od and control principle based on rotary tool holder are put forward,and the modeling and simulation of precision control method of NC lathe rotary tool holder are realized by using modeling software.The simulation results show that the precision turning and control of three degrees of freedom based on the rotary tool holder can improve the accuracy of the surface of the complex rotary surface,reduce the error,improve the stability,and can also realize adaptive dynamic changes of complex curved surfaces,integrity is better than ordinary turning.
