  • Patent number: 10977958
    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.

  • Publication number: 20170023417
    Abstract: A thermal displacement compensation device detects the temperature of a machine tool and the temperature of an environment in which the machine tool is placed, and estimates a temperature distribution in a machine component affected by the temperature of the environment from the relationship between the temperature of the machine tool and the temperature of the environment. Based on the estimated temperature distribution in the machine component, a position in the machine tool at which the time constant of the detected temperature matches the time constant of thermal displacement of the machine component affected by the temperature of the environment is found and set. Using temperature at the set position as a revised temperature of temperature detected by the machine temperature detection section, a thermal displacement amount of the machine component is calculated.
