"Continuous optimal infeed control for cylindrical

The controller performance is demonstrated on an instrumented internal cylindrical grinding machine. A new methodology is developed for optimal infeed control of cylindrical plunge grinding cycles. Unlike conventional cycles having a few sequential stages with discrete infeed rates, the new methodology allows for continuous variation of the infeed rate to further reduce the cycle time.
