Abstract
This paper focuses on solving the bottleneck problem-process simulation in virtual manufacture (VM), a solution of whole process simulation including geometrical aspect and physical aspect is put forward in the domain of laser surface hardening. For the difference of mechanisms among the different laser machining modes, the architecture integrated with the common and the distinction is constructed for the whole process simulation, and it is suitable for all laser machining modes. The virtual processing equipments for the laser machining are built by IGRIP software. The processing model is the map of the processing mechanism and the different models mapping to different machining modes. The whole process modeling of laser surface hardening is described. The extracted modeling parameters comprise geometrics, laser characters, material properties and mechanical properties, the model is built by artificial neural network method, and the finished model is embedded to IGRIP by quadric development. The whole virtual processing is implemented combining the whole model and the visualization simulation, the simulation result including the joints movement of the processing robot, collision-free report, processing effect prediction etc. are output. The analysis for the simulation result and the influence of parameters on processing effect are discussed to guide the real laser machining.
