[0013] In order to express the manufacturing advantages of the present invention more clearly, the present invention will be further described in detail below in conjunction with specific embodiments.
[0014] The invention uses CAD software to establish a three-dimensional model of the formed part. Firstly, the model is sliced according to the shape, structure and size of the formed part; secondly, the forming path is planned according to the size and shape characteristics of each layered slice. The numerical control codes required for the formation of each layer are used to control the movement of the numerical control machine tool to realize the accumulation and formation of each layer.
[0015] According to the quality requirements of the formed metal parts, determine the interlayer temperature distribution characteristics during the forming process, and then set the corresponding interlayer temperature control algorithm based on the thermodynamic criterion of molten pool stabili
