Introduction to Manufacturing

Module Three: Metrology

VernierCaliper

Metrology 

Goal: Learn about measuring tactics, tools and practices!  There are a wide variety of tools for accurately measuring items, a few of which are covered in this module, along with how machines are calibrated.  At the end, you will get a chance to use these tools to tolerance and properly measure a bar for manufacturing.  You will also get a chance to identify the sizes of ball bearings, measure surface roughness of gears and more.

Presentation & Readings:

  1. This module includes two shorter presentations (Both are required)
    1.  Metrology Presentation Part One
    2. Tolerance, Dimensioning and Surface Roughness Part two
  2. Readings:
    1. Calibration information for roughness (Optional)

Videos & Resources:

REQUIRED VIDEO: You only need to watch about three minutes of this video.  This video covers the basics of calibration and why it is so important to manufacturing.

OPTIONAL VIDEO:  Interesting video on measuring the profile of a gas turbine engine using a coordinate measuring machine

OPTIONAL VIDEO:  Interesting video demonstration on automated deburring and surface finish.  Shows automation software in measuring and gauging various surface roughness.
