← TechnologyWhich failure outcome occurs when sensor ADC non-linearity accumulates in CNC mill axes?
A)Reduced part positional accuracy✓
B)Increased motor servo oscillation
C)Encoder signal phase distortion
D)Excessive spindle drive heating
💡 Explanation
In a CNC mill, ADC non-linearity introduces errors in position feedback; the control system interprets inaccurate positional data via the sensor, and inaccurately moves the axes. Reduced part accuracy ensues because the control loop corrects to an incorrect location, rather than motor oscillation, encoder error or spindle heating.
