Problems solved by technology

[0002] After the parts are layered and sliced, the program automatically sorts the cutting areas of each slice layer. The default sorting method is irregular, and there are many empty paths of the equipment. Some areas have serious heat accumulation, which affects the forming speed, efficiency and quality, it is necessary to manually adjust the order of the cutting areas, the workload is very large, and the scanning trajectory overlap rate between the original layer and the copied layer is high, which affects the combination between the original layer and the copied layer
Therefore, the traditional method has the problems of low forming efficiency and poor part quality.

Abstract

The invention relates to a laser deposition scanning path planning method. The method comprises the steps that forming zones for performing additive manufacturing are selected by means of two standards of a temperature value and distance; sequential order of the forming zones is controlled for avoiding ineffective strokes, lowering heat input to the maximum extent and improving the forming efficiency; and the scanning direction of a laser head is adjusted by 90 degrees for additive manufacturing, so that the associative property between layers is enhanced, and the quality of parts is improved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a laser deposition scanning path planning method. Background technique [0002] After the parts are layered and sliced, the program automatically sorts the cutting areas of each slice layer. The default sorting method is irregular, and there are many empty paths of the equipment. Some areas have serious heat accumulation, which affects the forming speed, efficiency and Quality requires manual adjustment of the order of the cutting areas, which requires a lot of work, and the scanning trajectory overlap rate between the original layer and the copied layer is high, which affects the combination between the original layer and the copied layer. Therefore, the traditional method has the problems of low forming efficiency and poor part quality. Contents of the invention [0003] In view of the above technical problems, the present invention provides a laser deposition...
