The invention proposes a high-efficiency batch additive manufacturing method, including three steps of process margin model processing, batch manufacturing model processing, and additive manufacturing. Among them, the processing of process margin model includes analyzing the structural characteristics of parts, comprehensively considering the machining and assembly requirements of parts and the direct forming accuracy of additive manufacturing, designing the process margin of blank parts for additive manufacturing, and obtaining the process margin model; batch manufacturing model processing includes According to the structural characteristics of the process margin model and the forming characteristics of additive manufacturing, the superposition and placement of parts for efficient batch additive manufacturing is determined. The formed part of the present invention has high dimensional accuracy, small machining margin, and good product performance; it can effectively improve production efficiency, material utilization rate and equipment utilization rate, effectively reduce production cost, effectively adapt to rapid production verification of complex structures, and promote Rapid iterative upgrade of equipment.
Description
technical field [0001] The invention belongs to the technical field of additive manufacturing processing design, and in particular relates to a high-efficiency batch additive manufacturing method. Background technique [0002] With the leap-forward improvement of advanced aerospace technology, a new generation of aircraft is developing rapidly in terms of high speed of sound, long range, and lightweight. New aircraft equipment has higher and higher requirements for the selection of materials and structural design of parts. Compared with traditional industrial fields, aerospace parts have the characteristics of complex product structure, high performance requirements, many types of non-standard structures, and low degree of mass production. . The application of a large number of complex non-standard structures puts forward higher requirements on the processing and manufacturing technology of products. Traditional processing methods have been difficult to meet the high-effici...
