Maximum allowable feed rate for reference-pulse Computer Numerical-Control (CNC) system is limited by the interpolator iteration speed. In other word, it means higher iteration speed corresponds to higher maximum allowable feed rate. To develop interpolator with higher maximum allowable feed rate, t...
