Abstract

Even now, in 21 century, there is no separately explained theory of simple cutter profiling, however, available theoretical bases of the wood cutting theory are capable to arm designers with necessary data. But it is necessary to look at considered object from the other side and to correct available data in some moments, to present in other light, otherwise, to line up to other mission, especially for cutting tool designing, for the analysis and profiling it’s cutting elements. Based on the functional element analysis were marked main cutter’s elements – front face, back face and cutting edge which is perpendicular to the cutting velocity vector. Elements of the simple cutting tool are: cutting edge, front surface, back surface. Elements and the whole of object functions were described in the natural form, with necessary imposition on them special conditions and limits. On the cutter-wedge main element is the cutting edge, the edge which located on the connection and at the end of the front and back faces of the cutter. This edge effect on cutting process: separation from the object of the part by the forceful, concentrated impact on the local area of this subject. V-shaped form of the cutting edge gives the required strength and rigidity, transfer the energy. Functional element analysis of the simple cutter showed that the interrelated elements of cutter – front and back, surfaces assist to cutting process function by cutting edge differently, depending on the thickness of the chips, rake angle and other cutting process conditions. In addition, assistance is limited by simple shape of the cutter-wedge. Therefore, to increase the efficiency of the cutting process reviewed elements of the cutter should be made more complex, equipped cutter with additional elements, adapt cutter to the specific terms and conditions of cutting process.
