摘要:
基于响应面法建立选区激光熔化成形工艺参数与点阵孔隙误差和致密度的数学模型,分析工艺参数对拱形点阵孔隙误差和致密度的影响规律,通过工艺优化获得内部致密、外部成形优异的工艺参数组合。结果表明,扫描间距与激光功率分别是影响点阵孔隙误差和致密度最显著因素,成形工艺优化组合如下:激光功率292 W、扫描速度1 095 mm/ s、扫描间距0.10 mm。优化后拱形点阵孔隙误差和致密度分别为0.65% 和99.20%,相比预测值,误差控制在5%内,表明所建立模型预测精度高,可有效实现对拱形点阵成形质量的预测与控制。
Abstract:
A mathematical model based on response surface experiments was established to correlate the process parameters of selective laser melting forming with the pore error and density of the arch lattice; analysis was conducted of the influence of process parameters on the forming quality of the structure, and the process was optimized to obtain an internal dense and externally well-formed process parameter combination. Results show that the scanning spacing and laser power are the most significant factors affecting the structure’s pore error and density. The optimized process combination for forming quality is as follows: laser power 292 W, scanning speed 1 095 mm/s, and scanning spacing 0.10 mm. The resulted arch lattice pore error and density after optimization are 0.65% and 99.20% respectively, with an error within 5% of the predicted values, demonstrating the high prediction accuracy of the established model and its effective capability for precise prediction and control of the forming quality of the arch lattice.
