Abstract
We explain an algorithm to do numerically controlled tapping. This dual predictive control algorithm achieves both high speeds and precise positioning. By predictively controlling z-axis motion and also predicting spindle-axis positions, we ensure good synchronization between these two motions. An experiment achieving tapping with 6,000 rpm/160 ms acceleration/deceleration, 6,000 rpm rotational speed and 20 micrometer precision is reported.
