摘　　要：合理的锻件余量设计,可以减少新产品试制时的废品损失,也可以减少金属材料的消耗与机加工成本。依据空间向量求和算法,提出一种全新的、基于数据统计的热轧环锻件余量设计方法。该算法将热轧环锻件几何方向的尺寸偏差及产品的表面缺陷视作空间几何向量,这些向量的叠加产生热轧环锻件的最小机加工余量;通过对生产线生产的产品进行测量和统计得到以上向量值,代表了生产线具备的实际生产能力。依据正态分布的概率密度,可预判产品最终尺寸的合格率。与以往的余量设计方法相比,该余量设计方法是以生产线生产出的产品的数据为依据,所设计的热轧环锻件余量更适合生产线的精度需求。该方法的应用可避免新产品试制时余量过大或过小,有效减少新产品试制时的材料浪费或废品浪费,也可用于其他如模锻、自由锻等产品。Reasonable allowance design of forgings can reduce the loss of scrap during the trial production of new products as well as reduce the consumption of metal materials and machining cost.Therefore,according to spatial vector summation algorithm,a new allowance design method of hot rolled ring forgings based on data statistics was proposed,which regarded the size deviation in geometry direction of hot rolled ring forgings and the surface defect of product as the spatial geometry vector,and the summation of these vectors produced the minimum machining allowance of hot rolled ring forgings.Then,these vector values were obtained by the measurement and statistics of the products produced by the production line,representing the actual production capacity of the production line,and according to the probability density of normal distribution,the final size qualification rate of product could be predicted.Furthermore,compared with the existing allowance design method,this allowance design method was based on the product data produced by the production line,and the designed rolled ring forgings allowance was more suitable for the accuracy requirements of the production line.The results show that the application of this method can avoid the excessive or insufficient allowance during the trial production of new product and effectively reduce the material waste or scrap waste,which can also be used in other products such as die forging and free forging.
