Which outcome occurs when the collet of a CNC lathe experiences excessive clamping force on tool shanks during high-speed aluminum machining?

💡 Explanation

Increased tool shank deformation occurs, because excessive clamping force initiates plastic deformation via the mechanism of "cold welding," particularly at high speeds. Therefore, the tool shank deforms, rather than maintaining its original geometry or benefiting from vibration damping under these elevated pressure conditions.
