Patent number: 6483269Abstract: A control apparatus for an automatic lathe includes a numerical controller, and comprises an input device, a readout section, and a machining program storage section. The input device inputs a machining program expressed by a predetermined language. The readout section reads out the machining program from the input device and digitizes it. The machining program storage section stores the digitized machining program into a timing table form in the order of execution. From the machining program storage section, various kinds of data such as the positional data of tools stated in the stored machining program, rotational data and movement data of a workpiece, and the like are sent out to an editing section. In the editing section, these various kinds of data are reedited and stored by a movement data editing portion.Type: GrantFiled: June 15, 2001Date of Patent: November 19, 2002Assignee: Star Micronics Co., LTDInventor: Tetsuya Sugiyama

Machining limit area specifying method and manuel feed machining method using numerical control unit
Patent number: 6269283Abstract: A machining limit area specifying method and a manual feed machining method using a numerical control unit capable of easily performing machining in a desired shape by manual feed. In specifying a machining limit area on an X-Y plane, a desired machining shape is defined by shaping data or a combination of some shaping data on the X-Y plane at a predetermined Z-coordinate, and the desired machining shape defined by the shaping data is specified as a machining limit area in which movement of a tool is permitted on the X-Y plane in manual machining using the numerical control unit. In specifying a machining limit area in the Z-axis direction, an inverse function using an X- or Y-coordinate value as a parameter is obtained based on a function for specifying the machining limit area on the X-Y plane on condition that a Z-coordinate value is used as a parameter, and the machining limit area in the Z-axis direction is specified based on the inverse function.Type: GrantFiled: May 19, 1998Date of Patent: July 31, 2001Assignee: Fanuc LimitedInventors: Satoru Shinozaki, Susumu Nagayama -
Patent number: 6243619Abstract: An operating state setting device and method of a plate material processing machine, includes multiple keys having corresponding functions relating to operation of the plate material processing machine. The keys include a skill mode selecting key for selecting an expert or beginner mode, an automatic mode key for executing a numeric control processing program, a manual mode key for allocating manual control of a movable member to the operator and moving keys for controlling the movable member in the manual mode. A numerically controlled controller is provided for setting an operating state of the plate material processing machine corresponding to the selected skill mode and executing a detailed procedure in the expert mode and a simple procedure in the beginner mode. The simple procedure may include an internal execution procedure and an editing history selection and corresponding product image display.Type: GrantFiled: April 2, 1997Date of Patent: June 5, 2001Assignee: Amada Company, Ltd.Inventors: Toru Inamasu, Kiyotaka Nishiyama

Patent number: 6161050Abstract: A numerically controlled milling machine is used to mill the surface of a coined spinnerette after punching and before broaching the holes in the spinnerette. A probe is mounted on the milling machine to obtain data points on the bumpy surface of the coined spinnerette. The low points in predetermined areas off of the protuberances on the bumpy surface of the coined spinnerette are detected. Splines connecting the low points in, e.g., concentric rings if the holes in the finished spinnerette will be in rings, are used to generate a representation of the finished surface. A spiral tool path is obtained using the representation of the finished surface and G-codes are generated to control the milling machine to move a tool along the tool path. After the coined spinnerette has been milled, conventional finishing, including broaching is performed.Type: GrantFiled: March 26, 1998Date of Patent: December 12, 2000Assignee: Eastman Chemical CompanyInventors: Ernest Edward Jessee, Michael Ray McLaughlin, Timothy Martin Pinto, James Emmett Grant, Jr.

Patent number: 6088627Abstract: A process for machining mechanical parts, including the milling of parts having a complex shape, includes the steps of determining the volume of the part to be machined, defining a corresponding machining grid, plotting the machining grid defined for the volume of the part to be machined, programming the plotted machining grid, and machining the part, grid line by grid line, according to the established programming. The process is implemented with an apparatus including a machining head coupled with a tool support. The tool support for the machining head (e.g., a cutting tool head) is positioned to face a predetermined point of the grid line to be machined, and immobilized. The machining head is mobilized to machine the desired grid line, with the tool support remaining fixed.Type: GrantFiled: June 6, 1997Date of Patent: July 11, 2000Assignee: Constructions Mecaniques des Vosges MarioniInventor: Francois Wildenberg

Patent number: 6009353Abstract: A controller for transferring information for managing and controlling machine tools, an automatic warehouse and a CNC device reads material information (e.g., size, shape, material) on an actual material on a pallet in an automatic warehouse before transferring a machining program for nesting. The controller judges whether the material information matches a material on which products are nested, newly nests the products of a machining schedule on the material of the material information when they do not match, and transfers the machining program for the nesting to the CNC device and machine tools.Type: GrantFiled: June 26, 1997Date of Patent: December 28, 1999Inventors: Kaoru Nakamura, Hideki Fujiwara
