中文摘要: |
针对可修复产品的成本问题,分析了产品生产过程中影响成本的主要因素,研究了可修复产品在制造过程中花
费的成本,提出了可修复产品公差成本模型。该模型可以确定设计公差、工艺均值和工艺公差的最佳值,通过调整工艺
能力指数值,降低了因产品质量原因造成的损失。以拨叉轴为例,应用该模型获得制造零件的总成本,并对单个零件修
复前后的单价进行比较,验证了本模型的有效性。应用结果表明模型不仅提高了产品质量还降低了产品成本。 |
英文摘要: |
ln view of the problem of repairable product cost. the various factors that affect the cost were analyzed, and
the product cost was studied during the process of mechanical product manufacturing. The tolerance-cost model of
repairable product was proposed. The optimum value of design tolerance, process mean and process tolerance could be
determined by using the model. The production cost could be reduced by adjusting the process capability index. A fork
shaft was used to obtain the total cost of manufacturing parts. Comparing the unit price for single part before and after
repair, the effectiveness of the model was verified. The result shows that the model not only improve the product quality,
and reduce the cost of production. |
