A machine learning apparatus determines a control parameter of an active vibration isolation apparatus on which an industrial machine is mounted. The industrial machine includes a movable part, a drive source that drives the movable part, and a drive source control section that controls the drive source to position the movable part at a command position. The machine learning apparatus includes: an acquiring section that acquires, as teacher data, a positional deviation, which is a difference between the command position and an actual position of the movable part; a storage section that stores a learning model that outputs the control parameter corresponding to a state quantity concerning the industrial machine; and a learning section that updates the learning model using the teacher data.

A parameter setting method includes a parameter value changing step of, when the magnitude of a deviation that is a difference between a command position and an actual position of a movable portion is greater than or equal to a prescribed value during operation of an active damper, selecting an unselected set of candidate values from among a plurality of sets of candidate values and changing the values of respective types of parameters of the active damper to the selected set of candidate values, and when the magnitude of the deviation is less than the prescribed value, not changing the values of the respective types of the parameters. After the parameter value changing step is finished, the parameter value changing step is repeated until the magnitude of the deviation becomes less than the prescribed value.

Parameter setting method and control apparatus

A linear motion mechanism includes: a shaft; a base member having a through hole through which the shaft can be inserted; a static pressure bearing provided between the shaft disposed in the through hole and the base member to slidably support the shaft relative to the base member by introducing a pressurized fluid to the shaft; and an annular member provided between the static pressure bearing and the base member to elastically support the static pressure bearing.

Linear motion mechanism, balancer device and machine tool

A temperature control system for a machine tool is equipped with a first temperature control device configured to control the temperature of gas supplied to a gas bearing, a second temperature control device configured to control the temperature of a room interior and to issue a notification of its own operation state to the outside, a gas supply section configured to supply gas whose temperature has been controlled by the first temperature control device, and a gas supply control section configured to perform the gas supply control of the gas supply section so that gas is distributed to both of the gas bearing and an interior space, when receiving the notification that the operation state of the second temperature control device is abnormal.

Temperature control system for machine tool

A mounting stand for an injection molding machine has a base member and an erecting member, to which an injection apparatus is attached, vertically arranged on the base member, and is movable with respect to a support supporting the base member. The mounting stand includes a base member protruding portion provided upward from the base member around a portion at which the base member comes into contact with the erecting member, and an anchored portion at which a side surface of the base member protruding portion is anchored to a side surface of the erecting member.
