Abstract
A new approach to obtaining three-dimensional cutting edges on a tapered cutting surface is proposed based on an image obtained on a measuring machine in the control section. The method is developed based on forming a spline and evaluating the shape using a unique algorithm, which is in turn based on an analytical mathematical model. The developed method allows estimating the main geometric parameters of the cutting edge and analyzing the shape of the helical groove of the drill. In the experiments, the drill was installed on a rotary table capable of adjusting the position around its axis. The validity of the new approach was corroborated by physical tests and analysis of the set of images obtained using an optical measuring system.
