Abstract

The active-lap optical manufacturing technology under computer control has many advantages in fabrication of large aspheric surface. As the lap is translated across the rotating workpiece, the lap's horizontal speed and rotation rate and the total force on the lap to the lap are dynamically controlled to reduce the residual surface error. In order to get the better convergence of the error, the material removal rate (MRR) and a new compositive strategy of lapping with the active-lap are presented. The compositive model is based on not only Preston's relation but also an adaptive fuzzy-neural algorithm, in which the adaptive part is developed to compensate the linear part through learning the feedback on the lapping process. The computer simulation and examination of lapping show good evidence of the effects of the fuzzy-neural model.
