    摘要:

    为了深入研究高档数控机床的加工精度检测机理,利用Adams和Matlab/Simulink软件平台对AC双转台五轴联动数控机床加工S试件的运动过程进行联合仿真。首先搭建了机床的机械系统和控制系统模型,然后将整机机械模型的6个输入变量和12个输出变量通过Adams/Control模块分别与Simulink建立的控制模型进行对接,完成系统输入、输出的设置,从而实现整机机电耦合的联合仿真。仿真结果表明五轴机床在加工S试件过程中各个轴的运动都呈非线性变化,与工程实际经验相符。

    Abstract:

    In order to deeply study the mechanism of machining accuracy detection for high-grade CNC machine tools,in this paper,Adams and Matlab/Simulink software was used to simulate the movement of S-shaped test piece produced by five-axis CNC machine with AC dual rotary table.Firstly,the mechanical system and control system model of the machine tool were built.Then the 6 input variables and 12 output variables of the mechanical model were docked with the control model established by Simulink through Adams/Control module respectively,and the settings of input and output in the system were completed,and the co-simulation of electromechanical coupling was realized.The simulation results show that the motion of each axis for the five-axis machine tool presents a non-linear change in the machining S-shaped test piece process,which is consistent with the actual engineering experience.
