  • Patent number: 11833630
    Abstract: In one aspect, a swiss-type machine tool is provided that includes a workpiece holding shaft, a workpiece supporting shaft, and a tool holder associated with the workpiece supporting shaft for holding at least one tool. The machine tool includes a drive operable to rotate the workpiece holding shaft and the workpiece supporting shaft around an axis. The workpiece holding shaft has a work holder configured to secure a workpiece to the workpiece holding shaft. The workpiece holding shaft is axially shiftable relative to the workpiece supporting shaft to adjust a position of the workpiece relative to the workpiece supporting shaft. The machine tool further includes a removable workpiece support, such as a guide bushing, configured to be releasably connected to the workpiece supporting shaft and rotate therewith. The workpiece support slidably contacts the workpiece and permits axial movement of the workpiece relative to the workpiece support.

  • Publication number: 20220274202
    Abstract: An additive manufacturing machine that includes a wire supply including a wire drive configured to advance a wire at a wire feed rate and a wire heater configured to apply resistive heating to heat the wire. The additive manufacturing machine includes an additive head for emitting a laser beam to weld the wire to a substrate, a sensor configured to detect a weld parameter, and a controller operatively connected to the wire supply, additive head, and sensor. The controller is configured to determine a failure mode of the weld as the laser beam welds the wire to the substrate based at least in part upon the weld parameter. In response to determining the failure mode, the controller is configured to adjust at least one of the wire feed rate, the resistive heating, and a power of the laser beam as the laser beam welds the wire to stabilize the weld.

  • Patent number: 10379523
    Abstract: A machining program editing assist apparatus includes a display controller. While the display objects are being displayed in either one of the program data display area and the process list display area, the display controller decides that a designated display object of the one of the display areas is the display object designated by the display objects of the one of the display areas and a specific point, differentiates the designated display object from the other display objects in the one of the display areas, decides that a designated display object of the other of the display areas is the display candidate of the other of the display areas, includes the designated display object in the display objects of the other of the display areas, and differentiates the designated display object from the other display objects in the other of the display areas.

  • Patent number: 9727222
    Abstract: A device includes a CPU and a touch-panel display. In a first display mode, when control functions that belong to a first level are assigned to menu switches of a plurality of menus, one of the menus is displayed. In a second display mode, all the menus are displayed. A change switch is provided in a menu display selection area, and includes a plural-row mark to indicate that a plurality of menus exist at the first level. The CPU switches between the modes to display one or all menus in the menu display selection area. When a plurality of menus exist at the first level, the plural-row mark is displayed; otherwise, the plural-row mark is erased. When the menus are displayed in the second display mode, the plural-row mark is lit. When the menu is displayed in the first display mode, the plural-row mark is unlit.

  • Patent number: 5052021
    Abstract: A digital signal decoding circuit of this invention includes a detection circuit, a reference signal generation circuit, and a discrimination circuit. The detection circuit detects central values of an amplitude in each bit of interest of a received digital signal. The reference signal generation circuit generates a reference signal having a signal value according to the central value detected by the detection circuit. The discrimination circuit compares the signal value of the received digital signal with a signal value of the reference signal generated by the reference signal generation circuit, thereby outputting a decoded binary signal.
