摘要 |
A system for applying ultrasonic energy to a workpiece, the system including a horn stack; a mounting system upon which the horn stack is mounted; a source of energy coupled to the horn stack; an anvil having a surface for supporting the workpiece; and a controller configured to receive a resonant frequency of the horn stack, and to determine a quantity standing in known relation to a change in gap between the horn stack and the anvil.
