Assembly Precision Prediction Method of Numerical Control Machine Tools based on Meta-action

  • 摘要: 装配是保证产品质量的重要环节,而装配精度是装配过程的重要度量指标。为预测数控机床最终装配精度,利用“功能-运动-动作(Function-Movement-Action,FMA)”的功能分解原则对机床的装配过程进行结构化分析,将机床分解至基本动作单元-元动作;构建基于元动作的装配误差传递层次架构图,清晰地表达了各装配单元间的装配关系及几何特征之间的逻辑关系;以几何特征误差在装配过程中的传递与积累为基础,构建多层次状态空间模型预测数控机床最终装配精度;以某数控加工中心的Z轴进给功能装配单元为例,验证了该方法在机床装配误差预测中的可行性。
