Paper Abstract

Active lap technology is usually used in the manufacture of large optics. As the feedback element, force sensor plays an important role in the lap control system. With regard to the condition that the calibration of pulling force sensor is completed manually and inefficiently then the process of calibration data is complicated, a new automatic calibration technology of force sensor is developed. In which the method of data acquisition, computer control, curve fitting and error analysis are integrated in the calibration process, so the efficiency and reliability of force calibration is improved observably. The result of calibration can satisfy the requirement of the control system of active lap.
