Abstract

The 5-axis CNC milling machines are complex mechanical systems, and they can be designed with hundreds of 5 degrees of freedom mechanisms. The kinematic and dynamic modelling of machines is crucial for optimising the machine design and the milling process. However, formulating the dynamics model of 5-axis milling machines has never been proposed so far. Moreover, efforts have been made to develop kinematic models for the machines; however, formulating the generalized kinematic model for all possible 5-axis milling machines in closed form is challenging. In this paper, a novel method of kinematic and dynamic modelling for the entire family of 5-axis milling machines is developed. First, the special features of the machines family are fully studied to formulate effectively the generalized forward and inverse kinematic equations in closed-form. Second, by treating each 5-axis mechanism as a closed mechanism subject to a nonlinear kinematic constraint characterizing the machining process, the dynamics model for the whole family of 5-axis milling machines is successfully formulated, and the inverse dynamic equation is derived in closed-form. Finally, to demonstrate the importance and impact of the proposed method, useful applications were conducted; and these were supported by both numerical simulations and actual cutting experiments. Compared with previous works, our study includes new generalized equations of kinematics and dynamics for the family of 5-axis milling machines, and useful applications of the proposed equations for optimization of the 5-axis machining.

五轴数控铣床是一种复杂的机械系统，可以设计成数百个五自由度机构。机床的运动学和动力学建模对于优化机床设计和铣削过程至关重要。然而，迄今为止，还从未有人提出过五轴铣床的动力学模型。此外，人们一直在努力开发机床的运动学模型；然而，以封闭形式为所有可能的五轴铣床建立广义运动学模型具有挑战性。本文为整个五轴铣床系列开发了一种新的运动学和动力学建模方法。首先，对机床系列的特殊性进行了充分研究，从而以闭合形式有效地计算出广义的正向和反向运动方程。其次，通过将每个五轴机构视为受加工过程非线性运动学约束的封闭机构，成功地建立了整个五轴铣床系列的动力学模型，并以闭式推导出了逆动态方程。最后，为了证明所提方法的重要性和影响，我们进行了一些有用的应用；这些应用得到了数值模拟和实际切削实验的支持。与之前的研究相比，我们的研究包括五轴铣床系列的新的广义运动学和动力学方程，以及所提方程在优化五轴加工中的有用应用。
