SHORT TERM FIX FOR IMPROVING MEASUREMENT SYSTEM

 

Measurement system analysis

Chapter 13

Improving the Measurement System

Gauge incapable :

Repeatability  ( Gauge )

           Take multiple measurement and use average. 

             ( short term fix )

• Mistake proofing  

        ( e.g. provision of tooling to hold part during measurement )

• May need maintenance. 

Reproducibility  ( Operators )

• Use 1 operator  ( short term fix during improvement only )
• Have several operators measure the part and take the average  ( short term fix )
• Ensure consistency  ( training SOPs , WIS , ..... )
• Mistake proofing  ( e.g provision of tooling to hold part during measurement )
• Calibrations on the gauge dial may not be clear.

   Reproducibility       operator × part interaction.

•        Identify cause of interaction and then as operator.
