NAME EHiNA, Intelligent Tool Wear Measurement
EHiNA is an intelligent system for monitoring cutting tool wear, developed by IMH. Its main objective is to provide direct, accurate, and real-time measurement of tool condition during machining processes, through the analysis of process data (operation, material, tool, etc.), time series (energy consumption and vibrations), and images of cutting tools. The system enables the reduction of downtime, optimizes tool usage up to the end of their useful life, and supports maintenance decisions based on objective information, thereby enhancing efficiency and sustainability in advanced manufacturing environments.
