| dc.description | In this research, the implementation of simultaneous trilateration to measure three-dimensional, dynamic computer-numerically controlled (CNC) contours using the laser ball bar was investigated. The motivation behind this work is the desire to perform rapid, pre-process verification of CNC part paths without machining a test part. This reduces scrap and increases process efficiency. A prototype simultaneous trilateration laser ball bar (STLBB) system was designed, constructed and tested. Verification testing of the STLBB system was also completed. This investigation was composed of two parts: (i) comparisons between dynamic, two-dimensional paths measured both with the STLBB system and with an optical grid encoder; and (ii) static and dynamic reproducibility evaluation. Good agreement between the STLBB system and independent measurement devices provided authentication of the STLBB measurement capabilities. Once the validity and reproducibility of the STLBB system as a dynamic measurement tool had been confirmed, several three-dimensional CNC contour measurements were performed at micrometre-level accuracy. |
