浅谈刀具在PFMEA中的潜在失效因素

汽车行业零件的机加工PFMEA的潜在失效,一般的工程技术人员考虑的主要对象是机床对产品质量的影响,很少把刀具、化学品、检具、维修、操作影响也一道考虑进去.文章提出了刀具在PFMEA中的潜在失效因素及控制手段,对控制计划的编制完善,保证产品质量具有一定的支持作用.

Discussion on the Failure Factors of Tools in PFMEA

About the failure modes introduced in PFMEA in auto industr y,many engineers will just consider the equipment as the main factor w hich can influence the product quality,while less attention was paid to the che mical, tools, gages, maintance and operators which all can affect the product qu ality. The tools failure and the methods to control it better will be mainly dis cussed in this article,it will be helpful to work out the control plan,and als o be helpful to guarantee the product quality.
