Abstract
The effect of cutting speed, feed rate, depth of cut and tensile strength on the residual stress distribution in the machined surface region caused by milling of five different materials are determined using Eddy Current and Hole Drilling Strain Gauge techniques. The analysis of experimental data is carried out using Minitab software. The results show that residual stress is low tensile at the machined surface and increase with an increase in depth beneath the surface reaching a maximum tensile, then decreases with a further increase in depth, eventually becoming vanishingly small. The residual stress is found to be strongly dependent on both milling condition and tensile strength of work material.
