    • A method for producing ultrasonic vibrations at a preselected amplitude in a workpiece (10). The method includes the steps of: providing a clamping element (82) having a surface to engage the workpiece; relatively moving the clamping element (82) and workpiece (10) between (a) a first relative position wherein the surface of the clamping element is spaced from the workpiece and (b) a second relative position wherein the surface of the clamping element is urged against the workpiece with a first predetermined force; energizing the surface of the clamping element from (a) a first state wherein the surface of the clamping element is one of (i) vibrating at a first amplitude and (ii) not vibrating to (b) a second state wherein the surface of the clamping element is ultrasonically vibrating at the preselected amplitude that is greater than the first amplitude; and coordinating relative movement between the clamping element and workpiece and energizing the surface of the clamping element to the predetermined amplitude so that the clamping element and workpiece realize the second relative position substantially at the same moment that the surface of the clamping element is energized to vibrate at the preselected amplitude.
    • 一种用于在工件(10)中以预选幅度产生超声波振动的方法。 该方法包括以下步骤:提供具有与工件接合的表面的夹紧元件(82); 将夹紧元件(82)和工件(10)相对移动(a)夹紧元件的表面与工件间隔开的第一相对位置和(b)夹紧元件的表面被推动的第二相对位置 以第一预定力对着工件; 从(a)第一状态激励夹紧元件的表面,其中夹紧元件的表面是(i)以第一幅度振动和(ii)不振动到(b)第二状态之一,其中, 夹紧元件以比第一幅度大的预选幅度进行超声波振动; 并且协调夹持元件和工件之间的相对运动并且将夹紧元件的表面激励到预定的幅度,使得夹紧元件和工件基本上在钳位元件的表面被激励以振动的同一时刻实现第二相对位置 在预选的幅度。
