← TechnologyWhich risk increases when machining a batch of tight-tolerance parts on a CNC lathe using flood coolant cycling between 20°C and 30°C?
A)Tool wear accelerates predictably.
B)Bacterial growth in coolant decreases.
C)Thermal expansion causes dimension variation.✓
D)Surface finish improves consistently.
💡 Explanation
Thermal expansion causes dimension variation, due to expansion and contraction of the metals because the coefficient of thermal expansion is non-negligible in high-precision applications; therefore parts deviate from specified dimensions, rather than tool wear, bacterial issues, better finishing happening.
