| description | The invention belongs to the technical field of laser material additive manufacturing, and particularly relates to a laser power regulating method based on model features. The laser power regulating method comprises the following steps that a special region with a complex structure in a model is obtained, slicing processing is conducted on the workpiece model, and preprocessing is conducted on thesplice contour of a special region in the contour data of each layer, the laser power of the point needed to be adjusted is calculated point-by-point; and the slice contour of a non-special region ineach layer contour data is filled in a conventional filling mode; and the process is repeated until layer processing of all slices of the workpiece model is finished, and finally the laser printing path data of the workpiece model is generated. According to the laser power regulating method based on the model features, the heat accumulation effect generated by excessively intensive scanning and printing of in the local re |
