← TechnologyWhich outcome occurs when the infeed rate is excessively high during creep-feed grinding of turbine blade roots?
A)Increased wheel wear and glazing✓
B)Reduced surface finish roughness average
C)Decreased thermal damage defects
D)Enhanced chip formation shearing action
💡 Explanation
Increased wheel wear and glazing occurs during creep-feed grinding if the infeed rate is too fast because excessive mechanical loads exceeds the bond strength, causing abrasive grains to shed prematurely, therefore reducing cutting efficiency, rather than achieving optimal material removal.
