Abstract
The article examines the problem of improving the efficiency of the hardening process for welded rod structures of transport machines. The relevance of this research lies in the need to improve the quality and reliability of load-bearing structures while simultaneously ensuring safe working conditions. This paper describes a robotic system that can improve the efficiency of the hardening process for welded rod structures of transport machines. The proposed robotic system includes a device for clamping and rotating the workpiece to be hardened, an actuator module with a ball-and-rod hardener, and a process parameter control system. Algorithms for generating tool paths and selecting machining modes that ensure specified quality parameters have been developed. The practical significance of this work is confirmed by the implementation results: the automated system increases the fatigue life of structures by 40–50% compared to manual processing. Working conditions are significantly improved, vibration levels are reduced, and manual operations in the processing area are completely eliminated.
