← TechnologyWhich consequence results when a CNC-milled aluminum part’s dimensions deviate outside tolerance?
A)Premature wear accelerates component failure✓
B)Increased hardness reduces material ductility
C)Surface finish improves unexpectedly and exponentially
D)Thermal expansion precisely offsets deviations
💡 Explanation
If CNC-milled parts exceed dimension tolerance, increased friction arises because of improper fit, therefore accelerating wear. The resulting component fails sooner because of excessive material loss, rather than benefitting from changes in its surface or by dimension compensation.
