  • Publication number: 20250144759
    Abstract: To accurately perform movement control of a moving body, a machine tool includes a feed driver that moves a moving body in the machine tool, a feedback controller that feedback-controls the feed driver in accordance with a state variable, a friction compensator that, to compensate for rolling friction that occurs in the feed driver, adds, in advance, a friction compensation value obtained from measurement data of rolling friction or a friction compensation value calculated using a rolling friction model to a command value to be input to the feed driver, and a reverse response reducer that reduces, using the state variable of the feedback controller, a reverse response that occurs due to addition of the friction compensation value.

  • Patent number: 12286977
    Abstract: A scroll casing has a scroll portion, a discharge portion provided with a discharge port, and a tongue portion. An extended plate has, in a cross section obtained by cutting in a thickness direction, a change point, at which an enlargement ratio of an area of the cross section is enlarged so as to be larger on a downstream side than that on an upstream side due to a change of inclination. In the extended plate, an angle ?1, and an angle ?2 satisfy a relationship of either 0??2<?1 or 0<?2??1. A distance L1 and a distance L2 satisfy a relationship of L2<L1.
