← TechnologyWhich 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.
