本文描述了一种评估流动成形工艺在特定部件制造中的适用性的方法。在确定可行的工艺计划之前,该过程首先筛选从组分收集中形成流动的潜在候选对象,然后对定量、技术和经济可行性进行详细评估。所描述的过程使用了从文献中得出的分析关系和标准。例如,使用极限强度预测的解析关系来评估定性的可行性。类似地,进行工艺验证,估计成形过程中的力和缺陷率,并对照阈值进行评估。为了评价经济可行性,提出了一种基于工序时间模型的混合成本模型。利用这些计算值,通过与报道的压下率和工艺参数进行比较,确定了生产的可行性。文章最后简要总结了将该工艺应用于工业案例研究的结果。
This paper describes a methodology for assessing the applicability of the flow forming process for the manufacture of specific components. The process starts by filtering potential candidates for flow forming from a component collection and then carries out a detailed assessment of quantitative, technological and economic feasibility before determining a viable process plan. The process described uses analytical relationships and criteria drawn from the literature. For example, qualitative feasibility is evaluated using analytical relationships for ultimate strength prediction. Similarly technological validation is done estimating forming process forces and defects rate which are evaluated against threshold values. A process time model is used to develop a hybrid cost model in order to evaluate economic feasibility. Using these calculated values production feasibilities are established by comparison with reported reduction ratios and process parameters. The paper concluded with a brief summary of the results of applying the process to an industrial case study.
