Increased machining performance through the use of vibratory cutting

Wed, 03 Jun 2026 00:00:00 +0400

Traditional machining methods are associated with a number of fundamental technological limitations. These include significant heat generation in the cutting area, leading to increased tool wear and thermal deformations of the workpiece, the development of undesirable self-oscillations (vibrations) that negatively affect the accuracy and quality of the surface, as well as problems associated with the formation and removal of chips that can cause damage to the treated surface. The use of vibration cutting methods offers a promising direction to overcome these limitations. Giving a cutting tool or workpiece controlled vibrations of a certain frequency and amplitude fundamentally changes dynamics of the cutting process. The mechanism of action of vibrations consists in the periodic disruption of the continuous contact of the tool with the chips and the workpiece. This leads to a number of positive effects: a significant decrease in the temperature in the cutting area due to improved heat dissipation during periods of absence of contact, effective damping of parasitic vibrations due to the intermittency of the process, easier chip breaking and removal due to its dynamic destruction into small segments, as well as the possibility of increasing the cutting depth without increasing negative phenomena. The combination of these effects of the vibration cutting method makes it possible to achieve significant improvements in the technological parameters of the process. As a result, the roughness of the treated surface is reduced, burr formation is minimized, the accuracy of observing the geometric parameters of the part is increased and, as a result, a significant increase in machining performance while increasing the durability of the cutting tool.

Development of a mechatronic module for automatic detection of power transmission line faults

This article presents the development of a system for detecting and classifying power transmission line (PTL) faults using multifunctional sensors, including an RGB camera, thermal imager, and passive radar, integrated into a mechatronic module. The article analyzes existing PTL monitoring systems and identifies their limitations. A new approach is proposed, involving the creation of a mechatronic module for automatic fault recognition in PTLs and the use of an unmanned aerial vehicle (UAV) with a high payload capacity equipped with various sensors. The methodology for designing the mechatronic module structure is described. Methods of fault detection are presented, as well as requirements for the control system.
