We propose a method for detecting the boundaries of the cutting edge and flank surface of
helical drills. To implement the proposed method, the drill is installed in a rotating holder on …

In this paper, a new method for determining the curvature of the drill's rake surface is
developed. The new method is based on the identified functional relationships between the …

This article proposes a method for finding the focal length for determining the coordinates of
the cutting edge on the toroidal section of the end producing surface, formed on the basis of …

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 …

The application of solid carbide tri-flute drills is important for machining high-precision holes.
The main advantages of a tri-flute drill are high productivity, very good self-centering and …

Within the scope of an extended monitoring of the production a 100%-control of the
workpiece is absolutely important. Especially the measurement of inside contours in small …

The helical groove, which has a complex shape in the radial section, strongly affects the
performance of solid ceramic mills. The accuracy of shaping is strongly affected by the size …

This paper presents novel approach to drill condition assessment using deep learning. The
assessment regarding level of the drill wear is done on the basis of the drilled hole images …

A new method for determining surface roughness based on improving the kinematics of the
milling cutter movement during micro-cutting has the advantage of the precise spatial …

In this paper, a new system for designing drills with a full parametric cycle of connection of
the main parameters of the rear surface of the drill, based on the identified functional …
