Abstract: In a temperature estimation method, a rotational speed of a spindle is acquired. Moreover, a temperature rise table and a temperature fall table are used to calculate a temperature of a bearing from the rotational speed of the spindle every time a fixed time elapses. The temperature rise table stores in an associated manner the rotational speed of the spindle and a temperature rise of the bearing due to rotation of the spindle in a predetermined fixed time. The temperature fall table stores in an associated manner the temperature of the bearing and a temperature fall of the bearing due to heat dissipation in the fixed time.

Abstract: A tool replacement apparatus according to the present invention includes: a turning tool magazine capable of attaching or removing a tool to/from a spindle of a machine tool; a tool replacement control unit which controls operations of turning the tool magazine and attaching or removing a tool to/from a spindle; and a setting unit which sets a rotatable range of the tool magazine. The tool replacement control unit includes: a determining unit which determines whether or not a designated rotation angle in an instruction for turning the tool magazine is within the rotatable range set by the setting unit; and a unit which stops an operation of replacing a tool when the determining unit determines that a designated rotation angle is out of a rotatable range.

Abstract: A display unit is controlled to display guidance such as to instruct an operator to move a spindle up and down near the Z-axis position at which the tool is transferred between a grip and the spindle and to observe a lateral movement of the tip of a tool at the same time. Then, when the tip of the tool moves laterally, the display unit is controlled to display guidance to instruct the operator to raise the spindle and turn a turret so as to reduce the lateral movement of the tip of the tool.

Abstract: A learning model is constructed for adjusting control information so that a cycle time becomes shorter while also avoiding the occurrence of overheating. A learning model construction device includes: an input data acquisition means that acquires, as input data, control information including a combination of an operation pattern of a spindle and parameters related to machining in a machine tool, and temperature information of the spindle prior to performing the machining based on the control information; a label acquisition means for acquiring temperature information of the spindle after having performed the machining based on the control information as a label; and a learning model construction means for constructing a learning model for temperature information of the spindle after having performed machining based on the control information, by performing supervised learning with a group of the input data and the label as training data.

Abstract: A cutting fluid passageway that supplies a cutting fluid is disposed in a machining space (inside of a machine tool) of a machining tool isolated by a cover. The cutting fluid passageway is formed so that the upper portion thereof is opened in the passageway direction. Then, the cutting fluid is supplied from the cutting fluid passageway to a workpiece and a tool during machining or to the inside of the machine tool on which scattered chips produced by the processing are accumulated.
