Fortunately, the correct cutting speed can estimated with reasonable accuracy from tool-life graphs or form the Taylor tool life Relationship, provided that necessary data are obtainable.

The resonance frequency shift in the space atomic clock prototype is analyzed in the paper. The preliminary results show that a higher accuracy is obtainable in the proposed new prototype.
