  • Patent number: 8701529
    Abstract: A method of grooving a work-piece of superalloy uses a grooving cutting insert at least partially covered with a Cubic Boron Nitride (CBN) layer and having one or more interior ducts formed therein which open out to the insert's rake face at one or more corresponding openings. One or more coolant fluid streams, conveyed via these interior ducts at a pressure of no less than 200 bars, are directed upwardly and outwardly toward an interaction area between a cutting edge of the cutting insert and the work-piece, to thereby limit lengths of work-piece chips created during the grooving operation. The openings of the cutting insert's interior ducts may be located between 0.5-3.0 mm from the insert's cutting edge.

    Abstract: An electronic control system is programmed to control movement of a cutting tool relative to a rotating workpiece. After engagement of the stock, the tool is controlled to follow a curved path until the cutting surface of the tool reaches a predetermined depth of cut in the stock. The tool is then controlled to follow a straight/linear path, with the cutting surface of the tool engaged with the stock at said predetermined depth of cut. The control system varies the feed rate as the tool rolls into cut along a known path of curvature, to control the thickness of the material which is removed as the tool rolls into cut, e.g. to induce fracture as the material begins to coil. The feed rate as the tool rolls into cut is programmed to vary in relation to an arc of engagement between a cutting surface of the cutting tool and the stock into which the cutting tool is being moved.

  • Publication number: 20130139660
    Abstract: Methods are described for calibrating a turning machine having a first rotatable portion or chuck for holding a workpiece. The first rotatable portion has a first feature associated therewith. The method comprises the steps of using a measurement probe to determine the position of the first feature, rotating the first rotatable portion through an angle, and using said measurement probe to determine the new position of the first feature. The extension of the technique to swivel head mill-turn machines is also described.

  • Patent number: 8453544
    Abstract: A feeder for rods into a lathe by a motorized thruster for sliding and pushing a rod along a guide towards a processing lathe until the rod is taken by the lathe. An automatic control device actuates the thruster to advance according to a first thrust value and a sensor detects the movement of the thruster. If the sensor detects a minimum movement or no movement at all a thrust increase is commanded up to a predetermined maximum value. If the thruster does not move at all, this indicates jamming.

  • Publication number: 20130104706
    Abstract: A method for processing an inner face of a housing having an opening, in particular a housing of a driving mechanism, by means of a machine tool, which has a multiaxially movable tool retainer. A tool retained by the tool retainer is introduced through the opening into the housing, which is stationary relative to the machine tool, and the tool is moved along a circular path and in the direction of the housing in order to process the inner face. In order to create advantageous method conditions, the control head of the tool retainer that accommodates the tool is driven in a rotational manner by means of an angle drive on the tool retainer in order to move the tool independently of the axes of motion of the machine tool along a circular path in order to process the inner face.

  • Patent number: 8424427
    Abstract: There is provided a roll surface machining method and apparatus for using a cutting tool to carry out ultra-precision machining in the surface of a roll with a reduced amount of data. The apparatus and method for roll surface machining includes setting a machining start position of a cutting tool with respect to the surface of the roll by C-axis indexing of the roll and positioning of the roll in the axial direction (Z-axis direction) both with respect to the cutting tool. Also the cutting tool and the roll are moved relative to each other in the axial direction of the roll by position control using C-Z axis interpolation, thereby forming a three-dimensional pattern in the surface of the roll.
