IT 250 - Coordinate Measuring Machine


Credit Hours: 2

Provides students with a thorough understanding of coordinate metrology. The emphasis is on geometric measurement and inspection techniques as they pertain to a Coordinate Measuring Machine (CMM). This course also covers construction, calibration, operation and maintenance of CMM's.

Course Outcomes
Upon successful completion of this course the student will be able to:

  • identify quadrants and be able to make measurements and calculations relative to the Cartesian coordinate system;
  • plot various X&Y coordinates on graph paper;
  • using the CMM and a sample part, demonstrate the ability to:
    • translate the part coordinate system in the X,Y&Z axis;
    • rotate the part coordinate system in the X,Y&Z axis; and
    • store and recall the part coordinate system.
  • explain and define machine coordinates and part coordinates;
  • identify measurement planes for various features on a CMM test piece;
  • using the CMM and a sample part, demonstrate the ability to:
    • display machine coordinates;
    • recall precious measured features and establish a part coordinate system; and
    • recognize an incomplete coordinate system.
  • define various geometric features;
  • using the CMM and a sample part, demonstrate ability to measure each of the geometric features;
  • explain how geometric dimensioning and tolerancing is a dimensioning system which thoroughly defines a part;
  • list advantages of geometric dimensioning and tolerancing;
  • demonstrate how datums are established using a CMM;
  • demonstrate proper technique for hard probe calibration;
  • demonstrate proper technique for touch probe calibration;
  • explain the differences between mechanical and air bearing systems and the function of both;
  • identify at least four materials utilized in the construction of CMM's;
  • use proper cleaning techniques and solvents for various parts of a CMM; and
  • properly and safely use a CMM to accurately measure part features to print specifications.
