Abstract

The article is dedicated to the optimization of low-current wire electrical discharge machining for the production of precision micro-components under conditions of constrained thermal input. The relevance is determined by the increasing demand for high-accuracy elements in aerospace, medical, and micro-engineering applications, where conventional machining regimes introduce excessive thermal damage. The work describes the transformation of erosion mechanisms under reduced discharge energy and studies the interaction between electrical parameters, dielectric behavior, and material response. Special attention is paid to the restructuring of the discharge process, where stability becomes dependent on synchronized parameter control rather than energy intensity. The work sets itself a task to explain how low-current regimes reorganize the machining system and to identify the conditions under which dimensional accuracy and surface integrity are improved. Analytical synthesis of recent studies is used to solve this problem. The conclusion describes the transition of WEDM from a high-energy removal process to a controlled sequence of micro-scale interactions. The article will be useful for engineers and researchers working with precision manufacturing and advanced materials processing.

Keywords: Low-Current Machining, Micro-Components, Surface Integrity, Discharge Stability, Process Optimization.
