Abstract: A cutting insert for a ball nose end mill includes a body including two opposed substantially flat retention surfaces. Each retention surface includes a chip control groove thereon extending from a point at or near an axial center of the body at an angle relative to the axial center of the body. The insert further includes a peripheral surface joining the two retention surfaces, wherein the peripheral surface includes a locating surface at a first end thereof and two arcuate surfaces at an opposed, second end thereof extending rearwardly from approximately the axial center of the second end and positioned on opposite sides of the insert symmetrically with respect to the centerline of the insert. The arcuate surfaces each including an arcuate cutting edge at the intersection of outer portion of a chip control groove and the arcuate surface. The arcuate surfaces are formed with a face clearance angle under the cutting edges.

Abstract: Methods and systems are described to automatically lock and unlock a front axle disconnect mechanism in an all-wheel drive (AWD) system responsive to driving conditions to reduce parasitic losses and increase fuel efficiency. A control algorithm is described which automatically determines whether the front axle disconnect mechanism should lock or unlock responsive to various sensor readings throughout the vehicle. The sensor readings relate to the driving conditions. Advantageously, the present disclosure automatically decides the best mode for optimum fuel economy while safely responding to driving conditions, and therefore removes the requirement for a driver to select the operating mode.

Abstract: A method of treating a tool includes texturing at least a region of at least one surface of the tool to increase surface roughness and friction resistance. The tool may be in a variety of forms such as a cutting tool insert. The texturing process may be carried out by any suitable method such as laser beam impacting, grinding, sandblasting, molding, chemical etching, photolithography, and/or reactive ion etching. Tools made by the method also are disclosed.

Abstract: The method and apparatus for picking a lock which utilizes a single blade or pair of elongated thin, rigid, interchangeable blades which are to be inserted within the keyway of the lock. Each of the blades have an upper hiatused surface and can have an off-center sharpened edge so that the sharpened edge will contact the cylindrical lock pins of the lock spaced from the center of each of the lock pins. The off-center sharpened edge could be formed by beveling the side of the blade or by making a cut-out in the blade. The hiatused surface of the blades cause the “V” shaped tips of the cylindrical lock pins of the lock to move lineally with the sharpened edge causing the lock pins to pivot. Instead of a hiatused surface, there could be used one or more deflectable members, tufts of bristles or a brush. The blades are to be driven in a reciprocal manner with one blade moving in and the opposite blade moving out.
