Abstract

The small work volumes of Micro/Meso-scale Machine Tools (MMMTs) often present problems for calibration and error compensation, but also allow solutions not practical on the traditional scale. Measuring tool position with a separate metrology frame and compensating for error motions is one such solution. The metrology frame design follows principles of precision design and allows measurement of the position of the tool tip with respect to the workpiece while minimising Abbe errors. Kinematic analysis provides the relationship between metrology frame measurements and machine tool coordinates. Error analysis reveals that sensor error has the only first order influence on measurement accuracy.
