A curved surface layering method suitable for additive manufacturing

The invention belongs to the technical field of additive manufacturing, and discloses a curved surface layering method suitable for additive manufacturing, which comprises the following steps of: (1)determining the growth direction of a part to be layered and drawing a growth line; (2) solving an intersection point of the growth line and the surface boundary of the to-be-layered part, connectingthe obtained intersection point into line segments, and solving the length of each line segment; (3) determining the number of layers according to the length of each line segment and the thickness ofa single layer, layering the to-be-layered part by adopting an equal-layer-thickness layering mode or a variable-layer-thickness layering mode, recording coordinate values of division points, and determining the number of layers where each division point is located; and (4) storing the division points of each layer according to a preset sequence, solving boundary points of each layer, forming point clouds of each curved sur
