Title: Innovations by Yukihiro Shimogaki
Introduction
Yukihiro Shimogaki is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of coated tools, holding a total of 9 patents. His work focuses on enhancing the performance and durability of cutting tools through innovative coating technologies.
Latest Patents
One of his latest patents involves a coated tool that features a base and a coating film. This coated tool includes a first surface, a second surface adjacent to the first surface, and a cutting edge located on at least a part of a ridge part of the first and second surfaces. The coating film consists of an AlTiN film that includes titanium, aluminum, and nitrogen. Notably, the first aluminum ratio and the second aluminum ratio are both 0.7 or more. The first aluminum ratio is defined as Al/(Al+Ti) at a point located 0.1 mm away from the cutting edge, while the second aluminum ratio is measured at a point located 0.2 mm away from the cutting edge on the first surface. Importantly, the second aluminum ratio is larger than the first aluminum ratio. Another patent describes a coated tool that also includes a base and a coating film. This coating film has a first compressive stress in a direction parallel to the surface of the base, intersecting with the cutting edge at a right angle, and a second compressive stress in a different direction, also intersecting at a right angle. The first compressive stress differs from the second compressive stress, showcasing the complexity of his designs.
