Which outcome occurs when quantization errors in an absolute encoder compromise CNC mill positioning?

A)Vibration amplitude increases drastically
B)Workpiece surface finish degrades visibly
C)Increased thermal expansion appears
D)System accuracy is greatly improved

💡 Explanation

Lost steps accumulate irrecoverably due to coarse angular discretization because of quantization errors which leads to inaccurate tool paths; therefore, the workpiece finish suffers noticeably, rather than thermal shifts or amplified amplitude, because the tool's movement becomes jerky and imprecisely controlled.
