In order to study the effect of rolling texture on the cutting mechanism, cold-rolled aluminum alloy and brass plates which have distinctive preferred orientations were used as materials to be cut. Orthogonal cutting was performed by changing the angle e between the rolling direction and the cutting direction, and change in cutting phenomenon with θ was examined. Moreover, the obtained experimental results were analyzed by r-value and the anisotropic parameters which were determined from tensile tests of the same plates. The results showed that the effects of plastic anisotropy of the material appeared clearly at the cutting force, that is, cutting shear stress τ_s was affected by the harmonic mean value r in shearing direction.
