| Abstract: | Based on force and deformation analyses of chuck and workpiece at high speed turning,a new analytic computation model of dynamic clamping force for the chuck with centrifugal force compensation(CFC) was built and verified by means of experimental investigations.The clamping characteristics at high speed turning such as the loss of dynamic clamping force,centrifugal force compensation efficiency and clamping force hysteresis were investigated.Some problems of design and application of modern chuck with CFC were discussed.The study results provide reliable theoretical and technical supports to reasonably utilize the potential of modern chucks at higher rotational speed and guarantee a safe high speed turning process. |
