用于后处理翘曲控制的对组件的预处理应力加载
Abstract:
本发明揭示一种抵消因微应力的堆积而产生的翘曲效应的过程及设备，所述微应力的堆积因用长波长激光器机器加工部件而导致。在不使待机器加工的所述部件中的任何其它特征屈曲的情况下，使用用于固持所述部件的固定件沿由于机器加工所致的翘曲应力的相反方向对所述部件施加预应力。当将所述部件固持于所述固定件中的预应力位置中时对其进行机器加工。
Abstract(English):

A process and apparatus neutralizes a warp effect resulting from a build up of micro strains caused by machining a part with a long wavelength laser. The part to be machined is pre-stressed in an opposite direction of a warp stress due to machining using a fixture for holding the part without yielding any other features in the part. The part is machined while held in the pre-stressed position in the fixture.
