The deceleration function based on the acceleration of AI HPCC / AI NANO
HPCC automatically calculates the optimum feedrate according to the geometry.
Depending on the geometry, the calculated feedrate may become very low.
If this occurs, to prevent the feedrate from becoming too low, deceleration to a
feedrate below that specified for this parameter can be suppressed.
If, however, the override by the deceleration function based on the cutting load is
enabled, the feedrate may become lower than the lower feedrate limit.
