Course Description:
FARO’s CAM2 inspection software packages for the FARO Arm. They are engineered for computer-aided measurement supporting 3D feature measurement/inspection and CAD-to-part comparison.
More About This Course
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.
