    摘要： A method for automatically sizing a ground surface utilizes a detector having a reference edge position provided adjacent the rotatable spindle of a jig grinder. The jig grinder spindle center is moved a distance from the detector's reference edge equal to the finished radius value of the surface to be ground, or any known distance to be used as a datum. A tool or grinding wheel mounted for relative movement to the jig grinder centerline along the U-axis is moved relative to the jig grinder centerline to clear the detector's pick-up edge. Then, with the grind side of the grinding wheel facing the detector pick-up edge, the wheel is lowered and outfed back along the U-axis while in a conventional dynamic grinding mode until the wheel's outermost cutting position is equal to or in proximity to the detector's reference edge position, which can be confirmed by laser, force or sound apparatus. When contact is made, the outfeed is instantly stopped with no over-travel. This U-axis radial position relative to the position of the machine spindle centerline is the automatically sized radius value to be ground in the workpiece and is a datum or preset radial position to which the tool is moved relative to the jig grinder spindle centerline during the grinding mode.

    摘要： A force transducer and circuit are used to detect the edge of a rotating grinding wheel. The force transducer produces an output signal indicative of a force applied thereto. The output signal is filtered by a high pass filter coupled to the output of the transducer. The amplitude of the filtered transducer output signal is compared to a reference value. An output pulse is produced if the amplitude reaches a predetermined level with respect to the reference value. A timer responsive to a first output pulse establishes a fixed interval during which the number of subsequent output pulses is counted. If the number of pulses counted during the fixed interval reaches a predetermined quantity, a control signal indicative of edge contact of the grinding tool with the force transducer is produced.

    摘要： A machine tool is provided with a controller for computing, as a function of an established radius and a preset feedrate, a rotational speed for rotating the machine spindle to provide a uniform surface speed at the working edge of a tool as the tool alternates between linear movement along an X and/or Y axis and arcuate movement along the C-axis of the spindle. A method is provided for gauging straight surfaces and adjoining arcs at a constant feedrate without interruption.

    摘要： The present invention relates to an automatic measurement system and the method of employing the system with a cutting tool device. The measurement system includes a tool holder for mounting a cutting tool. A measurement probe is automatically mounted and dismounted from the tool holder without removing the cutting tool. The tool holder is preferably affixed to a work support table which is adapted to support a workpiece to be machined and measured thereon.
