Abstract In recent years, requirements of “High value-added” has increased to the wire-cut EDM under the situation of the high precision requirement of industrial products or the high labor cost. For corresponding to them, focusing on “Improvement of performance being helpful for the practical cutting in factories”, we have developed advanced cutting technologies, various effective functions and a management tool for productions and quality data on our wire-cut EDM, ROBOCUT. One of the latest cutting technologies is “High precision cutting for thick work-pieces”, developed for resin molding die cutting. It greatly improves the straightness of thick work-pieces by our optimum discharge control. And we have developed “Automatic wire feeding function at the wire break point in taper cutting” that can thread the wire automatically when the wire breaks in a taper cutting of a press die with relief angles. It contributes to unmanned machining. The rotary table for ROBOCUT named “ROBOCUT CCR” expands the range of applications, so that various applications such as cutting tools, medical parts, etc, are available. The management tool for productions and quality data named “ROBOCUT-LINKi” can observe machine status in real time, and support the productions quality control, so that it can contribute to decrease the machine downtime. For factory automations, we have also promoted robotaization of ROBOCUT aggressively, and actually we have seen many ROBOCUT systems combined with FANUC robots in Europe and USA. We correspond to the needs of markets, and continue to develop new technologies to contribute to the worldwide manufacturing industry. Herein, we introduce the latest technologies of ROBOCUT.
