摘　　要：单点渐进数字化无模成型技术存在局部特征减薄严重尤其缺乏工艺参数对减薄率的影响。建立了标准工艺参数验证模型,对特征样件进行多轮试制。从层间距,进给量,加工速度,成型道次等关键参数出发,选择不同的参数组合进行验证,对交付的样件减薄率进行评价。其中提升减薄率最优参数组合:一道次成型,进给量为0.2 mm,刀路为单向等高线成型,进给速度为6400 mm/min时,减薄率为26%。该参数组合有助于样件的减薄率最优化成型。There is serious local feature thinning in the single point progressive digital dieless forming technology,especially the influence of lack of process parameters on the thinning rate.In this article,the standard process verification model is established and the characteristic samples are trial-produced in multiple rounds.From the perspective of key parameters such as layer spacing,feed,processing speed and forming path rank,different parameter combinations are selected for verification and the thinning rate of delivered samples is evaluated.Among them,the optimal parameter combination for improving the thinning rate:one secondary molding with the feed quantity of 0.2mm,the cutter path is unidirectional contour molding,and the thinning rate is 26%when the feeding speed is 6400mm/min.The parameter combination is helpful to optimize the parts thinning rate.
