- Abstract:
- Recently, higher accurate and large size Coordinate Measuring Machine (CMM) is required in industry (especially aerospace and energy field). In case of large size CMM, very long gauge blocks or step gauge need for its acceptance test and calibration. However, the high accurate manufacturing of long size gauge blocks is very hard. Then tester used normal size of gauge blocks using stitching method in order to cover its long range of CMM. International rule of CMM acceptance test “ISO 10360-2:2009” accepts to use laser interferometer calibrated with an iodine-stabilized He-Ne laser and its combination with gauge blocks.
We developed a calibration tool using laser interferometer and gauge block. In order to improve the measurement uncertainty, this new tool uses a short length gauge block and positioning unit with motorized driving system. And this tool links measuring software to achieve full automatic measurement and calibration. - Keywords:
