← TechnologyWhich consequence results when excessive collet pressure distorts workpieces in CNC lathes?
A)Geometric dimensioning and tolerancing deviation✓
B)Spindle bearing overheating failure
C)Cutting tool wear acceleration
D)Surface finish oxidation increase
💡 Explanation
Excessive collet pressure causes elastic deformation, thus affecting geometric dimensioning and tolerancing (GD&T) because the clamping force exceeds the material's yield strength and causes distortion, rather than thermal or chemical degradation. The workpiece deforms under excessive force.
