New Promising Approaches to the Design of Cutting Tools Based on the Search for Optimal Control Indicators

Cutting tools with shaped cutting surfaces are widely used in industry. Their use allows to improve cutting conditions and to increase productivity. The faceted cutting surface is formed by cutting edges of complex shape. Since, there does not exist a standard/conventional methods for controlling a specialized tool, the development of methods for controlling chips of a cutting wedge of a complex shape is of high importance. In this paper, an image processing algorithm that allows to search for the shape of the edge and find deviations in the form of a chip from the theoretical result has been developed. The algorithm helps to quickly transform from a digital image to the real scale of the cutting edges. The translation of the coordinate system of the measuring machine calibrate and control the angular position of the cutter during measurement. The approach to finding the coordinates of the cutting edge, developed in this article, includes an error elimination block with experimental verification of functional dependencies, which allows to quickly correct the angular position of the controlled tooth online. This can significantly increase the efficiency and speed of measuring end mills for adjusting the angular position and correction when controlling a multi-blade tool while evaluating the accuracy of the cutting edge and the magnitude of the chip on the back surface.
