Which consequence results when radial cutting forces excessively deform a CNC lathe's spindle?

💡 Explanation

When excessive radial cutting forces deform the spindle, self-excited vibration, or chatter, occurs because regenerative effects amplify small disturbances via dynamic instability. Therefore, the surface finish degrades and dimensions become unstable, rather than primarily affecting tool wear or overheating.
