摘要：Laser cladding forming (LCF) is a type of additive manufacturing technologies, which is promising in many fields such as individuation manufacturing, parts repair, green remanufacturing, and so on. However, uneven mesh model distribution and mutation points of layer shape are bad for LCF process. Aiming at these problems, the optimization methods of STL model and layer shape are proposed. To improve the smoothness of stereo lithography (STL) model, the STL model is optimized by the discrete Laplace mesh deformation method. Then, the smoothness of STL model and the uniformity of the triangular face in the model are both improved. The regularity calculation model is established to quantify the optimization results by radius ratio method. Regarding the turbine blade as a research object, the optimization of STL model for turbine blade is conducted, and the optimizing results of turbine blade STL model are quantified. To solve the problem of path point mutation of the cladding path for the robot, an optimization method based on the path interpolation of layer shape is proposed, which is verified by simulation and experiment.
