  • Publication number: 20200108505
    Abstract: A machine tool is disclosed which continues monitoring even when there is an obstacle such as swarf or a cutting fluid between a machining portion to be monitored and a visual sensor. A visual sensor is attached to an in-machine robot which is movable in a machine tool. A controller operates the visual sensor while judging influences of the swarf and the cutting fluid, automatically judges an orientation experiencing less influence, and executes monitoring from an optimum direction.

  • Publication number: 20190217396
    Abstract: A holder for clamping a tool includes a clamping mechanism for clamping the tool, and an exposed portion. The clamping mechanism is switchable between a clamping state and an unclamping state. The clamping state is a state in which removal of the tool from the holder is hindered. The unclamping state is a state in which removal of the tool from the holder is allowed. The exposed portion is exposed outside the holder and directly or indirectly and mechanically linked to the clamping mechanism. The exposed portion is pushed in one direction for movement to thereby switch the clamping mechanism to the unclamping state.

    Abstract: A shape-memory alloy valve device includes a shape-memory alloy wire configured to make a valve member perform an opening/closing operation and a valve actuation control unit configured to control an opening/closing operation of the valve member. The valve actuation control unit controls energization of the shape-memory alloy wire in accordance with an input valve open signal or an input valve close signal so as to make the shape-memory alloy wire contract by raising a temperature of the shape-memory alloy wire beyond an operating environmental temperature, thereby controlling valve opening/closing. A preheating unit heats the shape-memory alloy wire to a preset preheat set temperature by energizing the shape-memory alloy wire from a power circuit when the temperature of the shape-memory alloy wire which is measured by a temperature measurement unit is lower than the preheat set temperature.
