Which risk increases when a rotary encoder in a CNC mill's spindle suffers excessive mechanical vibration?

💡 Explanation

Inaccurate spindle speed reporting occurs because **encoder jitter** adds noise to the position signal, degrading accuracy. This causes deviation in the feedback loop. Therefore, spindle speed control becomes unreliable, rather than other effects linked to cooling or tool wear.
