在加工过程中，机床的动力学行为，如刀具振动、机械结构振动、进给系统的运动误差等，都会对加工表面产生影响。然而，动态激励对五轴联动加工表面的影响至今尚未得到研究。本研究针对五轴联动加工时，平移轴与旋转轴之运动误差对加工表面之影响进行探讨。测试所用的几何形状是圆锥台，它通常用于评估五轴数控机床的加工精度。在考虑进给系统动态特性的基础上，提出了一种五轴机床刀具运动轨迹和刀具姿态的仿真方法。根据仿真结果预测了圆锥台的加工表面。为了验证仿真结果的正确性以及各轴运动误差对加工表面的影响，进行了切削试验。试验证明，该仿真方法可以预测加工表面。根据切削试验和仿真结果，讨论了各轴运动误差对加工表面质量的影响。负责绩效考核的选择和同行评审。第六届CIRP国际高等教育会议国际科学委员会
In the machining process the dynamic behaviors of machine tools, such as tool vibration, vibration of mechanical structure, and motion error of feed drive systems, influence the machined surface. However, the influence of dynamic ehaviors onto the machined surface generated by simultaneous five-axis motion has not been investigated up to now. This study focuses on the influence of motion error of translational and rotary axes onto the machined surface generated by a simultaneous five-axis motion. The geometry used for the tests is the cone frustum, which is typically used for evaluating machining accuracy of five-axis controlled machine tool. A method to simulate the tool motion trajectory and tool orientation for a five-axis machine has been developed based on the modeling of he feed drive systems considering their dynamic characteristic. The machined surface of cone frustum is predicted based on the simulated results. In order to verify the validity of simulation result and the influence of motion error in each axis on the finished surface, cutting tests have been carried out. The tests have proven that the proposed simulation method can predict the machined surface. The influence of motion error in each axis on finished surface is also discussed based on the results of cutting tests and simulations.
