← TechnologyIn a CNC milling machine employing servo motors for axis control, which outcome directly indicates incremental encoder signal corruption?
A)Spindle speed fluctuations increase sharply
B)Vibration amplitude begins resonant amplification
C)The programmed path deviates increasingly✓
D)Coolant flow rates diminish to imperceptible
💡 Explanation
When incremental encoder signals are corrupted, proper real-time position feedback is lost; the position control loop degrades. Because the path-following becomes inaccurate (path deviates) due to lost steps in position feedback rather than vibrations. Therefore, path errors diverge rather than other system errors.
