Measurement System Analysis (MSA)

MSA is the study of measurement error committed by the operator while reproducing and repeating measurement data of parts using a measuring equipment. The Training coursework includes; Components of MSA; Resolution or Discrimination, Bias, Repeatability (Equipment Variation), Reproducibility (Appraiser Variation), Gage R&R, Part to Part Variation, Total Process Variation (TPV), Linearity, Stability, Calibration Plot, and Attribute R&R.

Programme Language: English/Hindi

Mode of Training: In-House/Open House/Individual

Participants: Junior, Middle and Senior level Engineering and Management Executives from manufacturing or service industry. Students of Engineering, Management, B.Sc./B.Com/ B.A. with Maths may also participate.

ROI: Participants can measure the risk of the failure of a product or a process and eliminate the responsible causes, skill development, and knowledge enhancement
