An Introduction to Dimensional Metrology

Course Description: This course was developed for operators and technicians who are/will be responsible for taking dimensional measurements using the common measuring instruments found in a machine shop or lab. Each section of the course includes hands-on exercises so that students become familiar with the use of each type of instrument. Gage error studies are used throughout the course to provide a basis of comparison for the capabilities and limitations of the various instruments.
