摘要
提出了虚拟激光柔性加工系统的体系结构,运用IGRIP建立包括虚拟场景和虚拟加工设备的虚拟激光柔性加工平台;以覆盖件模具表面激光硬化加工为例,综合分析其过程中各影响因素(几何、激光、材料等方面的因素),建立了基于神经网络的工艺力学模型,并嵌入到虚拟加工平台中,以实现包括几何仿真与物理仿真的完整仿真过程,预测加工效果,为真实加工提供有效依据。
The architecture of virtual system on laser flexible manufacturing was put forward. Virtual processing platform including virtual environment and virtual devices was built by IGRIP software. A new processing model about laser surface hardening was built based on neural network after analyzing the affecting factors such as geometrical surface, laser parameters, material properties etc. The model is embedded in the virtual processing platform to implement the whole processing simulation combined geometrical simulation and physical simulation. The processing effect that provides valid reference for the real processing is predicted by the simulation results.
