Abstract
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.
