英文摘要Thermal accumulation in the laser directed energy deposition (LDED) process is a crucial issue that can significantly affect the microstructure and texture of the deposited layer. In addition to the process parameters (including beam type, power, and scanning speed), the scanning strategy is also a significant factor that affects the temperature field. Most scanning strategies used in the past are heuristic methods due to the computation limit of the finite element model. In this paper, an optimal framework for the fast selection of scanning patterns for the LDED process is proposed. Firstly, a temperature field dataset is built based on the finite element simulation results of random scanning patterns. Secondly, a deep regression model based on skip-connected 3D convolutional autoencoder (SC-3DCAE) is developed and trained by the dataset for temperature field prediction. Afterward, optimal scanning patterns are quickly selected from randomly generated candidates using the validated SC-3DCAE model based on the thermal variance criterion. Finally, finite element simulations and a 50layer thin-wall deposition process are performed with the recommended optimal scanning pattern. The trained SC-3DCAE model shows high accuracy and fast prediction of the temperature field. The optimized scanning pattern achieves higher cooling rates and temperature gradients compared to the continuous deposition pattern. Smaller dendrite spacing and grain size are found in the samples with the optimized scanning pattern.
