Abstract
In the paper, the wood as natural fibre-layered composite is used to study the principles of effect in machining of such composites and provide the suggestion how to eliminate the unwanted effects in composite material cutting. The suggestion is not in special tool geometry, cutting tool material, toolpath strategy etc. but is based on basically different principle of machining. The actual research in cutting of composites is focused on orthogonal cutting as 2D process. We have to take into account the 3D behaviour of chip forming, as the workpiece material is non-homogeneous and directionally oriented. Thus, we studied the idea of so-called free cutting or cutting by straight cutting edge. The principles of such cutting were tested on wood as natural fibre - layered composite and the results are presented in the paper.
