制造业过程控制中的测试保证方法研究

A Study of Process Measurement Assurance Method in Manufacture Process Control

制造市场的激烈竞争要求制造业开发一种保证产品质量的过程控制 ,而不是依靠常规检测来找出造成重大经济损失的废品。在产品生产过程的研究中 ,文中采用连续校准的方法 ,给出确定和控制测量误差的过程测试保证方法。这个方法的应用和产品统计过程控制 (SPC)共同确定了产品的结果 ,即当在过程控制的测量中确定了有关测量误差后 ,相应的产品测试结果误差也就确定了 。

High degree of competitiveness in manufacturing markets has demanded to develop a method for process controls that build quality into products, rather than relying on inspection to sort out costly rejects. This article describes a process measurement assurance method that determines and controls measurement errors as the product is produced. The results of this method coupled with production statistical process control (SPC) determine the product values with a known certainty. When the measurement error is determined along with the product variation, the product error is known and further inspection activities are greatly minimized or eliminated.
