Tracking and Trending Manufacturing Metrics

See how to:

• Understand how control charts to identify special causes of variation.
• Build charts using Control Chart Builder
• Save Control Charts to PowerPoint

See how to:

• Build IR Charts
• Avoid issues related to missing values
• Limit data points to improve readability
• Automate reproducing your work using scripts created by JMP and by implementing techniques to make the x-axis scaling dynamic

See how to:

• Use two different approaches for handling control limits
  • Use and reuse the same fixed limits based on best case when the process was in control
  • Calculate limits each time you have new data
• Save control limits both to the column and to a new table
• Add control limits from a limits table to a table containing the variables for the control charts

See how to:

• Use JMP Profilers to find settings that will result in the lowest probability of defects
• Model the process and compare maximized process settings to those for minimized defects
