    Abstract: The present relates to a method for automatically determining a finishing recipe of a manufactured component. A non-finished 3D model, consisting in a 3D representation of the manufactured component at a non-finished stage, is received at a computer. And a finished 3D model, consisting in a 3D representation of the manufactured component at a finished stage, is received. The non-finished 3D model and the finished 3D model are further processed, to calculate a finishing recipe of one or more tool(s), The tool performs a finishing operation according to the finishing recipe on the manufactured component at the non-finished stage, to obtain the manufactured component at the finished stage. The finishing recipe may include a trajectory of the tool(s), an operational parameter(s) of the tool(s). The manufactured component may consist in a blade.

    Abstract: An improved electronic controller for the motor of a high-speed spindle attachment used in conjunction with a cnc milling machine. The controller comprises preventative circuitry that protects the spindle assembly of the attachment from overload accruing as a result of relatively moderate increases in torque demand during use. The controller senses the power level being used by the motor while it causes high-speed spindle rotation, and when it identifies a power consumption rate by the spindle that exceeds the operator pre-set maximum level determined to be safe for avoiding catastrophic spindle damage, the electronic controller sends a signal back to the computer controlling the axes of the cnc milling machine that is sufficient to slow, pause, and/or stop the feed-rate.

A driven feed-screw advances the cutter relative to the work. Hydraulic motors drive the cutter and the feed screw as well as a pump used to establish the hold-down power. The suction motor and pump are mounted in a separate oil-filled and pressure-compensated casing. Another small and portable casing provides diver-controlled hydraulic flow regulation for the cutter motor, the feed screw drive and the suction pump motor. By controlling the drive speeds, cuts can be made utilizing only the suction grippers to firmly hold the frame to the work. At the end of each cut, the cutter is manually returned and the suction released to permit the frame to be quickly repositioned and secured for another continuation cut.

  • Patent number: RE31304
    Abstract: A drilling machine comprises a ram movable up and down on a carriage slidably mounted on a horizontal crossrail. A toolhead is mounted on the bottom end of the ram for pivotal movement about a horizontal axis at right angles with the crossrail and is pivoted to a desired angular position by a first drive shaft within the ram via bevel gearing. Rotatably mounted in the toolhead for rotation about an axis lying in a vertical plane is a toolholder which rigidly supports a drill and which is driven from a second drive shaft within the ram via bevel gearings. Preferably, the machine further comprises a rack-and-pinion mechanism driven from the second drive shaft for securely but releasably locking a turning tool at the bottom end of the ram, so that the machine can be used also for turning operation as a workpiece is rotated on a turntable. This turntable is of course held stationary during drilling operation.
