At the mesoscopic scale, the milling deformation of complex components with micro-thin-walled features such as micro-channel cold plates and aerospace honeycomb materials is the main factor affecting their machining accuracy. In order to effectively control the deformation in the process of milling and improve the machining accuracy of micro-thin wall, this paper starts with improving the stiffness in the milling process of micro-thin wall. Firstly, the deformation control method based on the optimal tool path is proposed during milling the micro-thin wall, including the deformation control of micro-thin wall with cantilever boundary in asymmetric step milling and the deformation control of micro-thin wall with complex boundary in piecewise variable feed milling; secondly, a lots of micro-thin-walled milling experiments are carried out with different milling parameters, tool paths and cooling methods; finally, compared with the free milling, the thickness and surface morphology of micro-thin wall after milling under the two control strategies are analyzed to verify the effectiveness of the control strategy and determine the optimal control strategy.

在细观尺度上，具有微薄壁特征的复杂部件（例如微通道冷板和航空航天蜂窝材料）的铣削变形是影响其加工精度的主要因素。为了有效地控制铣削过程中的变形并提高微薄壁的加工精度，本文从提高微薄壁铣削过程中的刚度入手。首先，提出了一种在薄壁铣削过程中基于最优刀具路径的变形控制方法，包括非对称阶梯铣削中悬臂边界的薄壁变形控制和复杂边界的薄壁变形控制。在分段可变进给铣削中；第二，在不同的铣削参数，刀具路径和冷却方法下进行了许多微薄壁铣削实验；最后，与自由铣削相比，分析了两种控制策略下铣削后的微薄壁的厚度和表面形态，以验证控制策略的有效性并确定最佳的控制策略。
