The article proposes an algorithm for designing round shaped cutters by graphical and analytical methods. Depending on the shaped profile of the part, this algorithm systematizes the calculation and allows you to apply a unified approach and easily automate it. The purpose of the design is the possibility of automating and reducing the calculation time of shaped cutters and is based on determining the radii of the nodal points of the shaped cutter through projections between the nodal points on the horizontal plane. A feature of the proposed algorithm for calculating shaped cutters is the consistency and the possibility of automating calculations that are simple and visual.
