Abstract
A double ball bar (DBB) system is an imperative device for measuring contouring accuracy, error characterization and interpretation of machine tool performance in volumetric workspace. The advantage that makes it popular and widely used by machine users is its quick performance checking, easy to use, portability and minimizing the down time of machine tools. Periodic calibration of this system is vital to ensure its correctness by providing its accuracy information. An in-situ calibration method is devised by the authors to calibrate DBB for ensuring correct indication and its metrological characteristics. Direct calibration method is adopted and laser interferometer is engaged for this purpose. Calibration is carried out under controlled environment and results are reported and compared against its required accuracy, calibration curve is drawn for its further utilization.
