In Response To Work Or Work Carriage Patents (Class 409/149)
  • Patent number: 11772222
    Abstract: A machine tool system is equipped with a machine tool and a controller. The machine tool is equipped with a machine tool body and at least one temperature sensor that acquires temperature data of the machine tool body. The controller is equipped with a storage that stores the temperature data acquired in time-series by the temperature sensor, and an auxiliary power supply that supplies power to the temperature sensor and the storage when the supply of power to the machine tool body is stopped. The controller controls the machine tool by using the temperature data over a predetermined time range stored in the storage, and selects, in response to a charge state of the auxiliary power supply, the temperature data to be used in first control after the supply of power to the machine tool body is resumed.

  • Patent number: 6859988
    Abstract: One embodiment of the present invention is a compact, low-cost, lightweight, versatile and easy-to-operate, processor-controlled carving and multi-purpose shaping device (“PCCMPS machine”). The PCCMPS machine that represents one embodiment of the present invention is configured, in part, similarly to common, commercially available portable wood planers and ubiquitous laser and ink-jet computer printers, with work pieces fed into the PCCMPS machine in a horizontal direction. The PCCMPS machine includes a motor-powered cutting head that can power detachable bits to drill, cut, shape, and rout a work piece under processor and computer control. The cutting head may be translated, under processor control, back and forth across the surface of the work piece in a direction perpendicular to the direction in which the work piece is fed into the PCCMPS machine and moved by motor-powered rollers.

  • Patent number: 6830415
    Abstract: A portion (14a, 14b) of a chip remover (14) is defined to be vibratory to give an NC machine tool (MT 1) a vibration transferable onto a surface (FS) of a work (13) under a finishing by the NC machine tool (MT1), a decision is made whether the NC machine tool (MT1) enters the finishing, and vibration of the vibratory portion (14a, 14b) is controlled, as the decision is true. A chip removal method and an NC machine tool equipped with a spiral chip remover (113) as a chip remover have various chip removal rules for determining permission/prohibition of the operation of the spiral chip remover (113). This spiral chip remover (113) operates based on commands described in a machining program. When a command in the machining program is executed, the permission/prohibition of the operation of the spiral chip remover (113) is controlled according to the chip removal rules.

  • Patent number: 5895181
    Abstract: A feedrate and travelling distance before the feed orientation of a feed drive axis is obtained by analyzing NC programs when carrying out a machining action, and the lost motion correcting quantity corresponding to said feedrate and travelling distance is calculated by using the relationship obtained in advance by experiments. Furthermore, the lost motion correcting quantity obtained by calculations is overlapped onto the instruction value to a servo motor which drives the feed drive axis, when the feed orientation of said feed drive axis is reversed.

  • Patent number: 5348431
    Abstract: A precision cutting process machine aligns a workpiece to be subjected to a precision cutting process by a continuously rotating cutting tool relative to the cutting tool, and cuts the work into a predetermined pattern so as to form fine grooves at a predetermined pitch by a continuous cutting processes. The machine includes a main body base portion and an up-and-down moving table driven in the up-and-down direction with respect to the main body base portion.

  • Patent number: 4976025
    Abstract: A machine tool has an array work stations which includes a plurality of machining stations. A plurality of hydraulic pallet assemblies are provided to hold workpieces to be machined. The hydraulic pallet assemblies are movable along a main track which extends through the work stations. Each of the hydraulic pallet assemblies includes hydraulic actuators which operate clamps to grip a workpiece. A test station is disposed to one side of a path of movement of the hydraulic pallet assemblies between the various work stations. A motor at the test station is operable to move a pallet assembly from the main track to a secondary track located at the test station. A connector assembly at the test station connects hydraulic fluid pressure with the hydraulic pallet assembly to operate the clamp assemblies under the same hydraulic pressure that they are actuated at a work station.

  • Patent number: 4832544
    Abstract: The present invention provides an improved piston milling machine. The invention milling machine in a preferred embodiment incorporates a breakaway lift arm whereupon a workpiece caught in the machinery will not damage the lift arm assemblies of the machine. Any excessive loads causing the lift arm to break away will further signal the milling machine to cease operations.

  • Patent number: 4633620
    Abstract: Methods and apparatus are disclosed for processing of steel billets or the like to remove surface defects. A material-removing device such as a grinding wheel is automatically controlled to initiate removal of material at points where defects have been detected and to continue removal of material as long as cracks or other defects continue to be detected. In certain disclosed embodiments, an inspection is performed using magnetic particle or other inspection equipment, the initial removal of material being controlled therefrom. Thereafter, material-removal is controlled from signals produced by a probe which is carried in the removal device or adjacent thereto. In other disclosed embodiments, a thin layer of material is removed to permit detection of defects by a probe, the material-removal being both initiated and continued under control of probe signals.
