Problems solved by technology

However, due to the characteristics of layered molding, the different inclination angles of additive manufacturing technology have a great influence on the surface quality when forming inclined surfaces, that is to say, the surface quality of parts with different inclination angles formed by additive manufacturing technology is very different.
Usually we have high requirements for the consistency of the surface quality of parts, but when using additive manufacturing technology to form curved surfaces, the consistency of surface quality is difficult to guarantee

Abstract

The invention discloses a surface appearance adjusting and controlling method for an additive manufacturing technology formed inclined plane, and belongs to the technical field of additive manufacturing. The method includes the following steps that (1), a three-dimensional model of a part is established, the relative position of the part relative to a base plate is determined, and then the inclination angles of all the portions of the surface of the part relative to the base plate are determined; (2), the part is subjected to axial gradient segmentation according to dip angle information of the surface of the part; (3), all parts obtained after axial gradient segmentation are subjected to circumferential gradient segmentation; and (4), according to a gradient result and the corresponding dip angle information, different forming process parameters are configured for the different portions, and finally forming is carried out. The surface consistency generated when a variable-dip-angle curved surface is formed is greatly improved, and the surface quality of the formed part is improved.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and specifically relates to a method for controlling the surface morphology of an inclined surface formed by additive manufacturing technology. Background technique [0002] Additive Manufacturing technology (Additive Manufacturing), as an emerging manufacturing technology, has developed rapidly in recent years. This technology is based on the principle of discrete-stacking, and the parts to be processed are manufactured in layers in a layered manner. Due to the principle of layered molding, the molding profile of each layer can be changed greatly, which can make the parts not limited by the space shape, which greatly increases the shape freedom of the molded parts. Compared with the traditional subtractive manufacturing technology, the additive manufacturing technology can greatly reduce the waste of materials; at the same time, the additive manufacturing technology can form parts...
