| 摘 要： | 将基于传感器信息的智能型开放加工系统应用于曲面的高精度加工，提出了曲面加工误差的动态补偿方法。为预测加工误差的补偿量，建立了刀具弯曲模型，分析了刀具弯曲对加工误差的影响。实验结果表明，本系统可有效地提高加工精度，使加工误差降低1／3－1／4。

| Abstract: | This paper discusses the process to apply the open-architectured intelligent manufacturing system to the sculptured surface cutting. The real-time method of compensation for cutting errors was presented. A tool deflection model is developed to calculate the corresponding horizontal tool deflection at the surface generation points on the cutter. The sensitivity of the machining errors to tool deflections has been analyzed via the deflection sensitivity of the surface geometry. The ability of the developed system was verified by a machining experiment, and the cutting error was reduced to about 1/3-1/4. |
