Fig. 7
Relationship of the residual strain \(\varepsilon_{{x{\text{r}}\_0.10\;{\text{mm}}}}\) to the depth of cut and the cutting angle. The color of each bar corresponds to the value of residual strain \(\varepsilon_{{x{\text{r}}\_0.10\;{\text{mm}}}}\). Error bar represents the standard error. The data are not shown for the cutting angle and the depth of cut, 80° and 0.3 mm, respectively, since the strain was measured only two times (color figure online)
