EVALUATION OF MACHINING INDUCED RESIDUAL STRESSES IN 2014 A T6 ALUMINUM ALLOY USING INDENTATION METHOD AND ITS CO-RELATION TO DISTORTION DUE TO TOOL PATH LAYOUTS

In this work, effect of different tool path layouts on machining induced residual stresses and in turn on distortion in aluminum alloy 2014 A T6 were studied by calculating residual stresses using indentation method. Results showed that tool path layout effect the residual stress distribution and lead to distortion. Machining induced stresses by using pocket out machining were minimum leading to minimum distortion.
