  • Publication number: 20250172918
    Abstract: A machine control unit to control a machine tool, includes a user interface to receive inputs by an operator, and a processor configured to be electrically connected to at least one component provided in the machine tool. A memory stores instructions that when executed by the processor, cause the machine control unit to perform operations. The operations includes: displaying an initial power value in the display, the initial power value indicating an electric power consumed by each of the at least one component during running of the machine tool, receiving, via the user interface, a first input for selecting a target component from the at least one component, receiving, via the user interface, a second input including an operation parameter of the target component for changing the electric power consumed by the target component, and controlling the target component to operate based on the operation parameter.

  • Publication number: 20250144714
    Abstract: A turret lathe includes a turret and circuitry which determines whether a designated tool is attached to a designated mounting surface of the turret and which selects a specific operation pattern from operation patterns based on the determination. The plurality of operation patterns includes a first operation pattern executed when the designated tool is not attached to the designated mounting surface, and a second operation pattern executed when the designated tool is attached to the designated mounting surface. The first operation pattern includes rotating the turret about the first axis such that the designated mounting surface is brought to an indexed mounting position before the designated tool is attached to the designated mounting surface. The second operation pattern includes rotating the turret about the first axis such that the designated mounting surface with the designated tool mounted thereon is directly brought to the tool nose measurement indexed position.

  • Publication number: 20250116975
    Abstract: A machining simulation apparatus includes a memory and a processor. The memory is configured to store a plurality of constituent models, a plurality of holding unit models, a workpiece model, and a machining program. The processor is configured to set a specific tool model, select a specific holding unit model among the plurality of holding unit models, calculate a recommendation value of a protrusion length of the specific tool model with respect to the specific holding unit model, create an assembly model in which the specific tool model and the specific holding unit model are combined such that the protrusion length is either the recommendation value or a corrected value that is calculated by correcting the recommendation value, and virtually execute the machining program in order to determine whether the assembly model abnormally interferes with the workpiece model or any of the plurality of constituent models.

  • Patent number: 11998990
    Abstract: A machine tool includes a workpiece spindle being rotatable about a rotation axis of the workpiece and configured to hold a workpiece such that the workpiece. A tool holding device is rotatable about a tool rotation axis and configured to hold a turning tool via which turning is performed on the workpiece. A movement mechanism is configured to move the tool holding device such that the turning tool rotates relatively to the workpiece toward an arbitrary direction perpendicular to the rotation axis of the workpiece. Control circuitry is configured to execute a machining program, to perform the turning, which includes an additional code which designates a target cutting direction of the arbitrary cutting direction, and to control the movement mechanism to move the turning tool in the target cutting direction with respect to the workpiece while the control circuitry executes the additional code.

  • Patent number: 9873174
    Abstract: A turning controller includes a storage, a working program processing device, a command value setting processing device, an approach angle setting command amount calculator, and a command processing device. The storage is configured to store a working program and tool shape data. The working program processing device is configured to analyze the working program and to calculate and output command amounts. The command value setting processing device is configured to set an approach angle command value for defining an approach angle. The approach angle setting command amount calculator is configured to calculate, as an approach angle setting command amount, a B-axis command amount for controlling to cause the approach angle to have the approach angle command value based on the tool shape data. The command processing device is configured to output the approach angle setting command amount to the B-axis driver.

  • Patent number: 7313458
    Abstract: The NC device of the machining center has the data memory for storing exchange history and data concerning a tool therein when the tool has been manually exchanged. When the data concerning the tool is updated, the data memory also stores update history. The main control unit determines whether the tool is changed on the basis of at least either of the exchange history and the update history. On the basis of a determination result, the main control unit controls the spindle head moving unit to stop the tool as well as allows a caution about the tool to be displayed on the display unit.
