摘要
将多学科设计优化理论应用于数控机床综合误差补偿技术中,通过对数控机床进行系统划分,建立各个系统的误差分析模型,并运用多学科设计优化的方法对数控机床综合误差补偿过程进行优化,最终得到精密的数控加工指令。该方法能够避免用几何误差和热误差简单相加来代替综合误差的近似计算,从而提高数控机床的综合误差补偿精度。
Applied the multidisciplinary design optimization to synthesis errors compensation for CNC machine tool.The author built each analytical model of errors according to systematic compartmen-talization of CNC machine tool and determined the exact machining code based on the optimization of syn-thesis errors compensation for CNC machine tool using the MDO methods.This method can avoid an ap-proximate computing of the summation of geometrical errors and thermal errors instead of synthesis errors in order to improve the accuracy of the synthesis errors compensation.
