Assessing Mold Tooling Life 模具寿命评估T. J. Schorn Enkei America, Inc., Columbus, Indiana Copyright 2004 American Foundry Society ABSTRACT 摘要A substantial part of the cost structure for a permanent mold process foundry is tooling cost. 一个永久性模具铸造的成本结构中相当大的一部分是加工成本.This means that extending tool life is an important aspect of a cost reduction strategy for the PM shop. 对PM店来说,这意味着延长模具寿命是一种很重要的减少成本的策略.Because of the significant role tooling plays in the quality of permanent molded castings, tool life extension is an important topic for quality improvement as well. 因为加工在永久性模具铸造中扮演着一个重要的角色. 在改善质量方面, 延长模具的寿命也是非常重要的课题.Yet while the literature available to AFS membership discusses a variety of ideas for lengthening tool life, there is almost nothing written to describe how one actually measures tool life.然而至今, 国际文化交流组织成员讨论各种各样的延长模具寿命的点子的, 可利用到的文献, 几乎没有提到如何测量模具寿命的方法. A characteristic of such importance to cost and quality should be very carefully measured. 成本和质量如此重要的特性应该要能仔细的被测量.This article discusses the proper approach to use to measure permanent mold tool life. 这篇文章讨论了测量永久性模具寿命的正确方法.Practical guidance on the data gathering, calculation and evaluation of mold tooling life is provided. 在对模具寿命方面的数据采集, 分析, 评估提供了实用的指导.Examples from the author’s PM facility are provided to illustrate the terms of life measurement. Uses of the data are also explored to offer additional opportunities for cost and quality improvement.且提供了一些来自作者的实例去直观的阐明寿命测试的方法, 数据使用方面的探讨为成本和质量的改善提供了更多的契机.
