我公司MSA的GR&R接受准则20%
我们公司的企业标准,规定MSA的GR&R接受准则20%,没有按照MSA手册的规定.上次莱茵公司审核,开了不符合项, 审核员完全不听我们的解释,完全不懂行业技术.
我公司的客户除福特公司外,其他公司并没有要求MSA的特殊要求,但是并没有当时我们没有找到大众接受我公司MSA小于20%可以接受的证据,因为大众不做PPAP签字。
后来,公司老外找到VDA 5 ,因为大众也遵循VDA的要求,由于该文件是德文版,只有下面图片。
下面我的同事又找到MSA手册第77页:
For measurement systems whose purpose is to analyze a process, a
general rule of thumb for measurement system acceptability is as
follows:
• Under 10 percent error – generally considered to be an
acceptable measurement system.
• 10 percent to 30 percent error – may be acceptable based upon
importance of application, cost of measurement device, cost of
repair, etc.
• Over 30 percent – considered to be not acceptable – every effort
should be made to improve the measurement system.
Further, the number of distinct categories (ndc)32 the process can
be divided into by the measurement system ought to be greater
than or equal to 5.
红色部分翻译出来的意思是:以下准则作为一个通用的准则供参考.
我们公司是行业的霸主地位,企业标准的制定之初肯定是经过多方论证的,作为TS审核员,全然否定我们的企业标准,这一点我们一定会坚持到底.
