Repeatability vs Reproducibility

Repeatability:

→ An example is mentioned below:

Possible Causes of Poor Repeatability:

Reproducibility:

Possible Causes of Poor Reproducibility:

→ Repeatability and Reproducibility is an important parameter of. This is a very important concept to find out the Gauge R&R study.→ We can easily find the variation of the operator and gauge which helps us to improve our process.➨ It is the variation in measurements obtained,⇢ By one appraiser⇢ with one measurement instrument⇢ when used several times⇢ while measuring the identical characteristic⇢ on the same part⇢ in the same environmental condition⇢ repetition over a short period of time⇢ This is due to an error in gauge→ There is two possible cause are:[1] Equipment:⇢ Instrument needs maintenance⇢ or it should be more rigid[2] People:⇢ Environmental condition (Lighting, Noise)⇢ Physical Condition (Eyesight)➨ It is the variation in the average of the measurements made,⇢ By different appraisers⇢ using the same measuring instrument⇢ when measuring the identical characteristic⇢ on the same part⇢ This is due to operator error→ Measurement Procedure is not clear→ The operator is not properly trained in using and reading gauge.→ Operational definitions not established
