Aims & Objectives

  • The instructor will work with students to define or influence a metrology process providing controlled dimensional quality in engineering and manufacturing of an application specific to the students’ work environment carried out by using the laser tracker.
  • Students will apply learned topics in the course to practical situations so they gain an appreciation of the nature of the work.
  • The students will work towards defining a systematic approach to establishing the correct methodology and providing a measurement based process for managing an inspection job correctly.

This is done by associating the students’ knowledge of the fundamentals of measurement with the measurement science concepts:

Dimensional Metrology 

  • Introduce measurement uncertainties relative to dimensional metrology, sources of error, and the effect of the measurement environment
  • Define the difference between measurement accuracy and measurement error and tolerance limits
  • Introduce maintaining measurement traceability

Physical Metrology 

  • Application of measurement principles as applied to physical properties; for example, measurement of temperature (ambient and object) and monitoring scale change of the part being inspected
  • Identification of sources of error and applying techniques to minimize error

Quality Control and Inspection 

  • Application of methodologies for analysis of the results in the inspection process
  • Solution of quality problems to the inspection process
  • Reporting methodology to ensure positive and unambiguous transfer of technical information
  • Selected examples of applications: tooling building & certification, part inspection, first article inspection, alignment, and surface profiling.
