Patent number: 11977199Abstract: A device for evaluating characteristics of a target ground containing a metal component is proposed. The device includes a penetration probe having a main frame and a pair of side frames respectively installed at opposite side ends of the main frame, wherein each side frame has a lower end thereof extending downward from the main frame; a plurality of electrodes installed to be exposed to outside on the main frame; an electrode measurement part for measuring apparent chargeability of the target ground by applying power for measurement to the plurality of electrodes; and a main processor for calculating a weight ratio of a metal component of the target ground on the basis of the apparent chargeability measured by the electrode measurement part and calculating a volume ratio of the metal component of the target ground on the basis of the calculated weight ratio of the metal component.Type: GrantFiled: October 26, 2020Date of Patent: May 7, 2024Assignee: KOREA UNIVERSITY RESEARCH AND BUSINESS FOUNDATIONInventors: Jong-Sub Lee, Sang-Yeob Kim, Nam-Sun Kim, Joon-Ki Chun

Patent number: 10279401Abstract: Provided are a cutting insert and a tool holder on which the cutting insert is provided. The cutting insert includes a circular upper surface, a circular lower surface, a cylindrical lateral surface for connecting the upper surface and the lower surface, an upper cutting edge formed between the upper surface and the lateral surface, a lower cutting edge formed between the lower surface and the lateral surface, and a plurality of rotation-preventing parts provided at the lateral surface so as to prevent the cutting insert from rotating with respect to the tool holder. Each rotation preventing part includes an inner curved surface recessed toward the center of the lateral surface and convexly rounded so as to form concentric circles in conjunction with the lateral surface, and a stepped rotation-preventing surface parallel to the axial direction of the insert and connecting the inner curved surface and the lateral surface.Type: GrantFiled: July 21, 2015Date of Patent: May 7, 2019Assignee: KORLOY INC.Inventors: Sang-Yong Lee, Ki-Chan Nam, Nam-Sun Lee, Kane-Hee Lee, Sun-Yong Ahn, Young-Heum Kim

Patent number: 10112241Abstract: A technical object of the present disclosure is to provide an insert, which can maintain rigidity thereof regardless of a clearance angle of a clearance surface that forms a circular cutting edge. To this end, the insert according to the present disclosure includes a circular upper surface, a circular lower surface, and a clearance surface portion connecting the upper surface and the lower surface. The clearance surface portion is divided into first and second clearance surfaces along a circumference thereof, by a first wave line that forms a waveform of valleys facing the lower surface and mounts facing the upper surface.Type: GrantFiled: November 7, 2014Date of Patent: October 30, 2018Assignee: KORLOY INC.Inventors: Sang-Yong Lee, Ki-Chan Nam, Nam-Sun Lee, Kane-Hee Lee, Sun-Yong Ahn, Young-Heum Kim
