ACE metrology content

The online curriculum is composed of:

  • an introduction to manufacturing measurements, which covers measurement transducers for displacement, velocity, acceleration, strain, temperature, part dimensions, surface finish, and internal geometry
  • an introduction to measurement uncertainty, which includes a definition of terms, a description of measurement uncertainty evaluation, and a case study for density measurement
  • multiple choice quizzes to assess learning and track progress.

Step 1: Introduction to manufacturing measurements

  • Questions

  • Metrology is best described as:
  • A rotary encoder is used to measure the angular position of a shaft.
  • A piezoelectric accelerometer produces a voltage that is proportional to velocity.
  • A thermocouple is used to measure temperature.
  • A CMM may be manually controlled by an operator or it may be computer controlled.
  • A stylus profilometer does not touch the surface when measuring its profile.
  • Computed tomography is used to image internal features of manufactured parts to check for defects.
  • This field is for validation purposes and should be left unchanged.

  • Questions

  • The acronym NIST represents:
  • A measurement result should always be accompanied by the measurement uncertainty.
  • “The accuracy is 0.025 mm” is an acceptable description for a measurement device.
  • Variance is a statistical quantity that describes the distribution in measurement results.
  • When a measurement of a quantity includes several inputs, the combined standard uncertainty is used to describe the combination of the input uncertainties.
  • One standard deviation captures about 95% of the potential values for a normal distribution.
  • A uniform distribution is the same as a rectangular distribution.
  • This field is for validation purposes and should be left unchanged.
