Title: Innovations by Tatsuo Kuloda in Wire-Cut EDM Technology
Introduction
Tatsuo Kuloda is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of electrical discharge machining (EDM), particularly in wire-cut EDM technology. His innovative approach has led to advancements that enhance the precision and quality of machining processes.
Latest Patents
Tatsuo Kuloda holds a patent for a method and apparatus for achieving a fine surface finish in wire-cut EDM. This patent describes a wire-cut EDM method that allows for machining to a fine surface roughness of 1 μm Rmax or less. The invention utilizes two power supplies and an electrode polarity switching system. The first high-energy power source is employed for initial profile cutting, while adjustments to machining pulse parameters, feed rate, and offset are made to achieve increasingly finer surface finishes. The wire electrode is maintained at a negative machining potential, and a second power supply with smaller offset values is used for subsequent cuts to further reduce surface roughness. Ultimately, the offset is minimized, and the wire electrode polarity is reversed to create a fine finished surface.
