  • Patent number: 9921571
    Abstract: This application relates to methods for applying automated precision machining operations to an oversized workpiece with a compact computer numerical control (CNC) machining apparatus. By shifting an oversized workpiece through a working area of the CNC machining apparatus, the CNC machining apparatus can apply machining operations to any portion of the workpiece in an automated manner. To achieve precision results, a position of the workpiece is tracked as the workpiece is shifted through the working area. In some embodiments, a probe can be utilized to track the shifting of the workpiece by determining a location of a machined feature after a particular shift has been completed. In this way, a position of the workpiece can be tracked without having to rely upon tolerances inherent to a workpiece manipulator.

  • Patent number: 9033623
    Abstract: At a contact step in a tool radius adjusting method, a reference portion of a movable body provided radially movably on a housing of a boring tool and a position adjusting reference member fixed on a machine tool are brought into contact by sliding the movable body relative to the housing so that the position of a cutting blade comes to a predetermined position in a direction to go away from a rotational axis. Then, at an adjusting step, the position of the cutting blade relative to the rotational axis is adjusted by changing the relative position between a tool spindle holding the boring tool and the position adjusting reference member in a direction to come close to each other by drive mechanisms of the machine tool used for positioning a spindle head with the tool spindle relative to a workpiece in machining the workpiece with the cutting blade.

  • Patent number: 7533453
    Abstract: A method and system design and manufacture of the monogrammed faceted and stone adorned eyeglass lenses via a computer program allowing a design, intricate facet cuts and stone placement on a computer lens model. Software may utilize a touch probe or laser scanner to gather point data from a previously designed lens, converting the data to a computer model. The data is then used to send signals to an articulated robotic arm holding a lens shape. The robotic arm receives the commands from the computer, moving and rotating the lens shape against an abrasive wheel, rotating cutter blade or rotating drill thereby duplicating the facet cuts, slots notches or depressions or other designs contained in the computer lens model. Varying pressure is applied by the articulated arm and various degrees of abrasiveness of the abrasive wheel.

  • Patent number: 7476065
    Abstract: A printed board drilling method and a printed board machining apparatus capable of improving machining quality, such as improving positional accuracy of holes and true roundness of machined holes, and improving work efficiency by minimizing a runout of the tip of a drill. An extension of the drill extending out of a spindle when the drill is held by the spindle is defined in advance per type or mode of use of each drill. One drill is selected among a plurality of drills corresponding to a shape of holes to be drilled in the printed board and the spindle holds the drill so that the selected drill extends out of the spindle by the extension corresponding to the selected drill. Then, the move of the spindle with respect to the printed board is controlled and the selected drill is rotationally driven by the spindle to drill the printed board.

  • Patent number: 7387475
    Abstract: Apparatus for positioning and holding a tool (3) relative to a workpiece (35) comprising a carriage (1) for conveying the tool over the surface of the workpiece (35) and means (7, 9, 11, 13) for holding the carriage (1) onto the surface of the workpiece (35), the holding means being selectively switchable between a low grip state in which the carriage (1) is held against the workpiece surface whilst remaining capable of movement relative thereto and a high grip state in which the carriage (1) is held substantially fixedly to the workpiece surface for the tool (3) in use to operate thereon. Such an arrangement provides a robot capable of “crawling” over a workpiece (35) and carrying out precise manufacturing operations thereon.

  • Patent number: 7375361
    Abstract: The orientation of a machine 2 relative to a work-piece 10 is manually controlled by means of an alignment device 4. The device 4 includes a light source 24 rigidly attached to a foot 12 that is resiliently movably attached to the main body 18 of the device. The body 18 of the device 4 houses a light detector 26 for detecting a light beam from the light source 24, the position of the region on the detector 26 illuminated by the beam depending on the orientation of the machine 2 relative to the work-piece 10. The operator is provided with feedback on whether the machine 2 is correctly aligned with a target orientation (usually perpendicular to the surface) and concerning the direction of corrective movement required, if any.

  • Patent number: 7367756
    Abstract: In adjusting phase for work (W), the operation of mounting/dismounting a reference tool on a spindle (6) is dispensed with and so is a storage space for the reference tool, and besides, it is arranged that the thrust on the work (W) does not directly act on the spindle (6) at the time of this phase adjustment. In a machine tool in which a spindle housing (7) supporting the specifically directed spindle (6) for rotation alone is supported for parallel motion in orthogonal three-axis directions (XYZ) by a numerical control mechanism (4), in determining the phase for the work (W) is feed-rotated around a specific axis (S), it is arranged that with a reference block (9) fixed to the spindle housing (7), the work (W) is feed-rotated around the specific axis (S) to abut the phase reference section (W1) of the work against the reference block (9), so as to find the amount of feed-rotation of the work at the time of this abutment.

  • Patent number: 7170076
    Abstract: A tool operates with a guide system to identify the orientation of a tool on a work piece. In one implementation, the tool identifies its orientation with respect to a guide signal supplied by the guide system. In an alternate embodiment, the tool determines its absolute orientation, such as a (x, y) coordinate. The tool includes an action component adapted to alter the work piece, such as a cutting head in a router. A guide detector in the tool detects a position of a guide signal from the guide system. A location detector in the tool receives the position data and employs it to determine the tool's orientation. Based on the detected orientation, the tool decides whether any tool adjustments are necessary. Examples of tool adjustments include the following: adjusting the position of the action component, enabling or disabling the action component, and providing operating indicators to direct a tool operator's use of the tool.
