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.
