摘要：
为实现飞机蒙皮的自动化切边, 提出基于工业机器人的螺旋铣削方法. 针对螺旋铣削加工参数进行正交试验研究, 建立周向铣削力和表面粗糙度的经验模型, 并对刀具自转转速、公转转速、每公转进给量、每齿进给量及铣削深度5个加工参数进行极差分析, 利用相对灵敏度模型确定每公转进给量是影响周向铣削力和表面粗糙度最为显著的因素. 综合考虑加工质量与效率要求, 优选加工参数并进行试验验证. 实验结果表明: 机器人铣削蒙皮试验系统加工性能稳定, 加工效率达48 mm/min, 轮廓精度达±0.15 mm, 表面粗糙度在4 μm以内, 切边无毛刺, 实现了高效精确的蒙皮自动化切边, 为飞机蒙皮切边提供了一种新的方法.
Abstract:
An orbital milling method based on industrial robot was presented to trim aircraft skins automatically. First, the orbital milling parameters were studied through orthogonal experiment design  the empirical models of circumferential milling force and surface roughness were established. Then, the spindle speed, orbital speed, feed rate per revolution, feed rage per tooth the depth of cut were studied by range analysis. Relative sensitivity model shows that the feed rate per revolution has the most significant effect on the circumferential milling force and surface roughness. Considering the requirements of both processing quality and efficiency, the optimal set of process parameters was obtained verified by experimen. Results in dicate that the experiment system of robot milling skin works steadily and reliably, the machining efficiency is 48 mm/min, the contour accuracy is ±0.15 mm, and the roughness is less than 4 μm, even without burr. The proposed system provides a new automatic method for aircraft skins trimming.
