Technology

During automated CNC milling of turbine blades, which consequence results from stackup of tool and fixture tolerances?

A)Resonance frequency shifts occur
B)Surface finish degrades rapidly
C)Cumulative dimensional errors increase
D)Coolant fluid flow becomes turbulent

💡 Explanation

Increased cumulative dimensional errors occur due to tolerance stackup, a linear addition of individual tolerances, because each tool and fixture has variation that compounds through the sequence. Therefore, part dimensions exceed specification, rather than altering resonance or coolant behavior.
