    Abstract: A collaborative approach, incorporating a server for data transmission, security verification, and authentication verification, is implemented between a dental office and a dental laboratory to fabricate a designed dental restoration. A scanner is used in a dental office to take a scan of a patient's mouth. The dental laboratory designs the dental restoration with specialized design software taking into account the scan of the mouth as well as a prescription from the dental office. The parameters defining the designed dental restoration are contained in a design file. The design file is used to create milling specifications defining instructions for milling the designed dental restoration. The materials for the dental restoration are loaded into a mill, where the dental restoration is fabricated in accordance with the milling specifications. Security verification ensures authorized materials are used, and authentication verification ensures authorized materials and processes are used.

  • Patent number: 8702686
    Abstract: The present invention relates to an adaptable therapeutic, diagnostic or surgical guide for an intra-operative adjustment of a guidance element to a pre-planned position. An advantage and innovation of the present invention is that it provides a template or guide that adapts in a controlled way to a changed intra-operative anatomical situation compared to the default planned situation. This adaption maybe purely positional but it may also include force feedback. Feedback, either visual feedback or force feedback that results in an adjustment of a guidance element is also an aspect of the present invention. For example, the feedback can contain information either about the fit of the guide or template onto a bone (in case the guide or template fits onto one bone) or about the relative position of two bones of bone fragments (e.g. ligament tension between the femur and tibia).

    Abstract: In a machine tool having a rotary shaft for use in rotating a tool or a workpiece, a plurality of stable rotation speeds at which the chatter vibrations are expected to be suppressed, and at least one switching rotation speed across which a dynamic characteristic of a rotary shaft system changes are stored. The plurality of stable rotation speeds may be determined from chatter vibrations detected using a vibration detection unit. Optimum rotation speed that is a rotation speed to which a rotation speed of the rotary shaft is changeable without crossing the switching rotation speed is selected from the plurality of stable rotation speeds, and the rotation speed of the rotary shaft is changed to the optimum rotation speed. Thus, chatter vibrations generated during rotation of the rotary shaft can be suppressed effectively.

  • Patent number: 7534077
    Abstract: A surface of a workpiece is traced when a machining tool is pressed onto the surface of the workpiece under force control so as to find the positional data of the surface shape. This positional data is corrected by an error caused by a bend of a robot. The positional data is compared with the target shape of the surface, from which the burr is removed. A shift of the surface shape in the normal line direction is found. The burr generation start position, the burr generation end position and the height of the burr are found by the shift start position, the shift end position and the shift size. A machining program is made which is composed of a pass connecting the burr end position with the burr start position and also composed of a cutting pass for removing the burr, and the thus made machining program is executed. As the burr position is found and the burr is removed when the machining tool is moved to the burr position, the burr can be effectively removed.

  • Patent number: 5733079
    Abstract: 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.

The particular cuts in the profile line are analyzed and interrelated to define basic cuts which can be combined to form the final profiles. One tool of each tool stack provides a particular cut, and by precise positioning of the individual tools, the combination of sequential cuts provide the final profile. Each tool may form a complete cut, may overlap a previous cut to form a continuation of such previous cut or may form a cut which includes only a portion of its cutting face.

The routing apparatus is of the type in which a router is mounted on the end of a bar for extension over a panel to be routed and in which the router can be moved in any direction in a plane parallel to the panel by reason of the bar being mounted in a carrier for longitudinal movement in one dimension of the panel, and the carrier being mounted for movement parallel to the other dimension of the panel. The accessory comprises a radius arm which may be adjustably connected at one end to the bar and is slidably mounted in a pivot block mounted for movement in the same direction as the carriage. An adjustable stop on the radius arm limits its longitudinal movement and an adjustable stop limits movement of the pivot block whereby the router can be guided in a preselected curved path by causing the radius arm to pivot around the pivot block.
