Fig. 4From: Observation of machined surface and subsurface structure of hinoki (Chamaecyparis obtusa) produced in slow-speed orthogonal cutting using X-ray computed tomographyCT images of the machined workpiece obtained by type I chip formation. Cutting angle was 50° and depth of cut was 0.3 mm. The circled area in a and the bright areas pointed by white arrows in b and c indicate the compressed areas. White triangle in c indicates a poor surfaceBack to article page
