This course is designed to familiarize Engineers and Scientists with Metrology, the science of measurement. A quantitative analysis of design based on sound metrology principles will help engineers and scientists to design better products and services. In order to evaluate multiple solutions to the design, physical measurements are made and the data analyzed. Predictions need to be made on how well the design will perform to its specifications before full scale production begins. Tests are performed using prototype models, computer simulation, designed experiments, destructive and non-destructive tests, scale models and stress tests among the many other methods of evaluation. In this course, you will learn to apply end-to-end metrology across all disciplines involved in producing a product. The role of metrology in the various phases of a products lifecycle will be covered.
