Distribution of the strain normal to the cutting direction (\(\varepsilon_{y}\) and \(\varepsilon_{{y{\text{r}}}}\)) and CT image of the workpiece. Depth of cut was 0.3 mm; cutting angle was 50°. a Distribution of the strain \(\varepsilon_{y}\). b Strain \(\varepsilon_{y}\) detected along the dashed line drawn in a. c Distribution of the residual strain \(\varepsilon_{{y{\text{r}}}}\). d Residual strain \(\varepsilon_{{y{\text{r}}}}\) detected along the dashed line drawn in c. e Cross-sectional view (RT plane) of the workpiece obtained by X-ray CT scanning
