Course Objectives
Metrological Traceability — Know-how of traceability to validate results
- What is a VALID result?
- How does one maintain traceability?
- International vocabulary of metrology – Basic and general concepts and associated terms (VIM)
- Precision
- Gage R&R
- Bias
- How to avoid failing BIAS test
- When we fail BIAS, how do you move forward?
- Accuracy
Importance of Calibration — Applying the process to assure success
- What is a Calibration?
- Understanding errors inherent to CMMs
- Calibration intervals and interim artifact testing
Metrology Standards – Industry needs and Applications
- ISO 1 – it was the start to this successful application
- How are these standards tied to each other and within the industrial segments?
Measurement Technologies — Broad Overview of hardware and software solutions for the practical user
- Almost all the new technologies are software driven
- Manual, semi-automatic, automatic – Stationary as well as portable solutions
- International vocabulary of metrology – Basic and general concepts and associated terms (VIM)
CMM Specifications — Interpretation of published literature to facilitate proper use
- How to interpret a system specification?
- Is measurement uncertainty listed and if so, why is it important?
- TAR and TUR
CMM data collection and analysis criteria
- Hole fitting algorithm – know that they exist, what they mean, and how to choose which to use in each situation
- Least squares
- Maximum inscribed circle
- Minimum circumscribed circle
- Lighting considerations and how they affect the results
- Top vs. bottom lighting
- Fiber/fluorescent/coaxial (through the lens) lighting
- Light intensity (washing out edges)
- Color
- Contact CMM probing factors
- Probe type
- Probe size
- Probing contact/approach angle and Cosine error
