Knowledge modeling method for additive manufacturing process

Abstract

The invention provides a knowledge modeling method for an additive manufacturing process. The knowledge modeling method comprises the following steps: acquiring concepts involved in the additive manufacturing process; and constructing a relation constraint between the concepts, and constructing an additive manufacturing knowledge rule according to a constraint relation to obtain a knowledge model. By establishing the knowledge model, storage, retrieval and recommendation of the process planning scheme are realized, more complex knowledge and relationships can be expressed, and storage and retrieval of the knowledge are facilitated. Meanwhile, a proper process planning scheme can be effectively established based on knowledge association and rules.

Description

technical field

[0001] The invention belongs to the technical field of additive manufacturing, and in particular relates to a knowledge modeling method for additive manufacturing process. Background technique

[0002] Additive Manufacturing (AM) technology is a technology that uses the method of gradually accumulating materials to manufacture solid parts. Compared with the traditional material removal-cutting technology, it is a "bottom-up" manufacturing method, which has the advantages of material utilization. High efficiency and high degree of freedom in product design. In recent years, AM technology has achieved rapid development. Various terms such as Rapid Prototyping, 3D Printing, and Solid Free-form Fabrication express this from different aspects. Features of the technology.

[0003] However, compared with traditional manufacturing technologies, the additive manufacturing process planning process lacks effective management methods, and the reuse rate of experience a...
