Which outcome occurs when a lathe's tool post suffers deflection under load?

💡 Explanation

Increased chatter vibration results because deflection allows self-excited oscillations to build during cutting due to a loss of rigidity; therefore surface roughness becomes unacceptable due to resonance, rather than a smoother finish at the set parameters.
