Which outcome occurs when the tailstock on a lathe loosens during high-speed machining?

A)Chatter and surface Finish degradation
B)Increased tool wear progression rate
C)Increased spindle motor amperage draw
D)Coolant temperature increase linearly

💡 Explanation

Surface finish degrades because torsional 'chatter' resonance emerges; the loose tailstock lacks damping leading to amplified oscillations, therefore unwanted chatter occurs rather than stability, due to insufficient rigidity unlike cutting at slower speeds
