← TechnologyWhich outcome occurs when a lathe's tool turret crashes due to servo motor failure?
A)Increased surface finish roughness
B)Workpiece deformation beyond tolerances✓
C)Harmonic resonance within the workpiece
D)Reduced tool wear from lubrication loss
💡 Explanation
When the servo fails during rapid traverse, inertial forces cause plastic deformation because the lack of position feedback leads to uncontrolled force application, therefore causing deformation, rather than just impacting surface finish issues.
