### Clamping Force Calculation | What It Is & How .

The amount of force applied to a workpiece by closing and locking a clamp is called clamping force. It is an important calculation because it allows a clamp to have adequate capacity to resist external machining forces. Clamping force is determined by considering several factors including cutting force and workpiece material.

Get Price### Rotating unbalance Wikipedia

Rotating unbalance is the uneven distribution of mass around an axis of rotation. A rotating mass, or rotor, is said to be out of balance when its center of mass (inertia axis) is out of alignment with the center of rotation (geometric axis). Unbalance causes a moment which gives the rotor a wobbling movement characteristic of vibration of rotating structures.
