X-Chart Design for Quality Control by Amit Pandey is a document available to read on EtoBox.
The Precision Machining Company produces tools on an assembly line. The critical quality dimension is the diameter of a hole bored in the tools. Management wants to detect any shifts in the average diameter from 0.015 inches using an X-chart. Data from 80 minutes of production is provided, with the process average changing once. X-charts will be created with sample sizes of 4 and 8 to determine when to stop the process to check for changes in the average diameter.
