等离子熔积复杂金属零件的数字化制造方法
Digital Method for Plasma Depositing Complex Metal Part
摘要
Abstract
Aimed at the characteristics of plasma depositing metal part process, we proposed the combination slicing technology for the complex metal part, including single direction growth, multidirectional growth and gradient growth structure slicing method, to meet the requirement of the hybrid plasma deposition process. Then we introduced the path generation technology with global optimization characteristics based on Voronoi diagram method, and proposed the real-time control method of the plasma deposition current and feeding rate parameters, considering the performance of self-developed multiple axes digital hybrid plasma deposition platform. The effectiveness of the proposed method was verified by the cap shape pieces and hollow solenoid manufacturing experiment. This method solves the supporting process problems of hybrid plasma deposition complex metal parts, and eliminates the staircase effect of plasma deposition process by re-slicing, which improves the manu?facturing precision. It provides a relatively complete digital theory and technical support for plasma depositing complex metal part.关键词
