Such parameters as the geometry in the static coordinate system, the working length of the cutting edge and the cut layer cross-section are studied. Based on the previously obtained data the main features of straight cutters are described. Graphic charts of the considered parameters under the same processing conditions are shown. On the basis of theoretical data obtained recommendations on the choice of cutting tools are given.
