Evaluating & Monitoring Your Process Using MSA and SPC

Presenter: Jerry Fish

Quantifying Measurement System Variation and How it Impacts Your Process 

See how to:

  • Understand basic measurement system evaluation principles
  • Understand purposes and types of Gauge Studies
  • Understand considerations for conducting a Gauge Study: Random part order, time of day, operator confidentiality, following standard procedures, monitoring but not interfering with tests
  • Perform Continuous Gauge Study
    • Interpret Variability Gauge Chart, Gauge R&R Measurements, Variance Components for Gauge R&R
    • Run Crossed Tests
    • Select tolerance intervals or specifications (LSL and USL)
  • Perform Attribute Gauge Study
    • Interpret Gauge Attribute Chart, Agreement Reports
  • Use EMP method to achieve an interclass correlation perspective for classifying a measurement system
    • Interpret Range Charts, Parallel Plots, EMP Results, Gauge Classification
  • Understand purpose of Process Screening: To determine if process is steady, stable and predictable so you can use it to monitor future performance and/or evaluate impact of changes on the process
    • Examine Voice of Process: Is process in control and exhibiting minimal variance?
    • Examine Voice of Customer: Is process yielding good/best parts that are within specification?
  • Use Control Chart Builder to examine process capability
    • Interpret Individual and Moving Range Charts, Limit Summaries, XBar and R Charts, Process Capability Analysis
  • Understand purpose of Multivariate Control Charts introduced in JMP 15: To identify two or more interrelated process variables where the interrelation might impact process capability although the individual processes might appear in control
