← TechnologyWhich consequence results when a CNC lathe unexpectedly loses power during a facing operation?
A)Workpiece surface hardening occurs
B)Catastrophic tool-workpiece collision occurs✓
C)Spindle bearing lubrication failure rises
D)Deformation of the chuck increases
💡 Explanation
The likely outcome is a collision because tool servo motion immediately stops and loses its position relative to the workpiece, due to inertia of the still-rotating chuck; therefore, a catastrophic collision is highly likely, rather than surface imperfections or lubrication breakdown that needs time to happen.
