← TechnologyWhich consequence arises when a lathe's tailstock shifts during a steel workpiece cut?
A)Tapered workpiece dimensions result✓
B)Increased tool bit edge chipping
C)Harmonic resonance in the spindle
D)Excessive thermal expansion of frame
💡 Explanation
Tapered dimensions result because the tailstock misalignment induces non-parallel movement, and the **change in center distance** creates a difference in the radius. Therefore, tapering occurs, rather than even stock removal or unrelated vibrations; it only affects the cut piece.
