Abstract:

From data obtained using a method of indent pairs it was possible to analyse different residual stress states generated in high-speed milled specimens of AA 6082-T6 and AA 7075-T6 aluminium alloys. The present method integrates a special device of indentation into a universal measuring machine, allowing the introduction of elongated indents to significantly reduce the absolute error of measurement. Diverse protocols for operations of high-speed face milling allow us to compare residual stress tensors inherent to climb and conventional cutting zones. Through an exhaustive analysis of the Mohr’s circles corresponding to those zones, a relationship was detected, which expresses the sensitivity of both alloys to develop surface residual stresses.
