Minimizing Distortion in Machining

From Lambda Technologies

Distortion of the work piece during machining can result in costly increases in scrap rates. Residual stresses may be present in the original forging or casting. When machining away portions of the material relieves these residual stresses, the re-equilibration of the remaining residual stresses distorts the shape of the work piece. Secondly, machining and grinding operations used in finishing a component invariably induce residual stresses.
