Title:
ADDITIVE MANUFACTURING METHOD AND SYSTEM FOR FORMING COMPLEX METAL PART BY SUPERIMPOSING SHEET LAYERS
Document Type and Number:
WIPO Patent Application WO/2017/114104
Kind Code:
A1
Abstract:
Provided are an additive manufacturing method and system for forming a complex metal part by superimposing sheet layers. The method comprises: using a layer division device (901) to divide a three-dimensional data model of a part into multiple layers; using a processing and forming device (902) to process the respective layers to form metal sheet layers; and using a welding device (903) to combine, by means of diffusion welding or friction welding, the respective metal sheet layers into a metal part. In the invention, the compensatory combination of an additive manufacturing process with a subtractive manufacturing technique in a conventional machining process further expands and compensates the production capacity of the additive manufacturing process. The invention is applicable to manufacturing of complex metal parts, and satisfies high precision and finish requirements of the metal parts.
