Abstract: Measurement systems play a significant role in helping manufacturing organization to improve product quality. In this paper,we propose the idea for applying statistical process control(SPC) to monitor the measurement process. Firstly,we point out the differences between measurement process and production process and set up the model of measurement process,then introduce the identical distribution principle for monitoring the measurement process. Finally,the method of transformation to implement the principle is provided by an example,which is from practical measurement process.

Key words: Statistical process control, identical distribution principle, measurement system, transformation
