Recently, materials made of natural resources have been gaining attention. In particular, high expectations are placed on bamboo fiber. However, conventional bamboo fiber extraction techniques have problems, primarily involving quality, accuracy, and efficiency. To solve these problems, a new method of obtaining bamboo fibers with a machining center (MC) is proposed. NC programs are designed according to a cutting theory based on a geometrical tool path for cylindrical work. The experimental results verify that fiber shape can be controlled by adjusting the appropriate end-milling conditions with a spiral tool path. The fiber length is influenced by the axial depth of the cut, while the fiber diameter is influenced by the vascular bundle size, which is a component of bamboo. Therefore, considering the direction and size of the bamboo components, the desired bamboo fibers can be obtained with high quality and accuracy using end-milling with an MC.
