MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202614003569 A) filed by Sodick Co. , Ltd. on January 13, 2026, for Machine Tool And Thermal Displacement Correction Method For Machine Tool.
Inventors include Miyahara, Nishiki; Narishima, Asuma -; and Yamamoto, Yoshinobu.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: First temperature sensors (MS) are respectively provided on surfaces of a Y-axis moving body, an X-axis moving body, and a U-axis moving body that are machine body components (3, 4, 6). A second temperature sensor (AS) is provided on a frame (10F) located between a cover (10) and the machine body components. A first estimated temperature is calculated by correcting a detection temperature of the temperature sensor (MS) with a predetermined first correction coefficient (KM), a second estimated temperature is calculated by correcting a detection temperature of the temperature sensor (AS) with a predetermined second correction coefficient (KA). The second estimated temperature is added to obtain a synthesis temperature of each machine body component. A thermal displacement amount in a predetermined direction of the machine body is calculated based on the synthesis temperature, and thermal displacement correction in the predetermined direction is performed.
