In this research, a small coordinate measuring machine has been assembled using standard opto-mechanical parts, 3 precision carriages and a Keyence LT-8010 laser displacement measuring probe. A study was conducted to assess the
positioning accuracy of this machine by employing laser interferometry principles to measure error components of individual positioning carriages.

An error model of the small coordinate measuring machine was also developed to take into account these error components and compute the resulting positioning capabilities of this machine. From the analysis of linear and angular errors, it became clear that after 3 years of operation, the positioning carriages had developed faults that were affecting their normal working abilities. This research concludes by analysing the errors obtained from the measurement of the individual positioning carriages and determining possible causes for these errors
