      C. Mischke (The American Society of Mechanical Engineers (ASME), 1970)
      The size of a plate cam moving a translating, offset roller or knife-edged follower is sensitive to the magnitude of the offset. The designer should not omit the opportunity to reduce size ...

    • A Kinetic Hydraulic System for High Energy Rate Metal Forming 

      V. H. Larson (The American Society of Mechanical Engineers (ASME), 1970)
      A high energy rate metal forming concept is described that uses energy from a high velocity free piston impacting on a liquid. The piston is driven by compressed air. The characteristics of ...

    • Upper Bound Solutions to Plane-Strain Extrusion Problems 

      P. C. T. Chen (The American Society of Mechanical Engineers (ASME), 1970)
      A method for selecting admissible velocity fields is presented for incompressible material. As illustrations, extrusion processes through three basic types of curved dies have been treated: cosine, ...

    • Shear Stress in Metal Cutting 

      B. F. Von Turkovich (The American Society of Mechanical Engineers (ASME), 1970)
      Since the shear stress is the main parameter influencing the energy requirement in machining, the estimation of this stress remains one of the principal problems in the theory of chip formation. ...

    • A New Method of Making Square and Pentagonal Tubing 

      D. Lee; L. F. Coffin (The American Society of Mechanical Engineers (ASME), 1970)
      A new process of forming square and pentagonal-shaped tubes from round tubes by rotating the tube between three rollers is described. It is found that, depending on the ratio of the roller ...

    • Analysis of the Effect of Strain Hardening on Central Bursting Defects in Drawing and Extrusion 

      Z. Zimerman; B. Avitzur (The American Society of Mechanical Engineers (ASME), 1970)
      Central bursting defects in a strain-hardening material are analyzed. A criterion has been derived for the conditions that promote these defects, as a function of the coefficient of strain ...

    • Micro-Machining of Copper and Aluminum Crystals 

      B. F. Von Turkovich; J. T. Black (The American Society of Mechanical Engineers (ASME), 1970)
      The process of chip formation in copper and aluminum single crystals has been examined with a scanning electron microscope. The morphology of the shear planes clearly illustrates that the actual ...

    • Metal Flow Through Conical Converging Dies—A Lower Upper Bound Approach Using Generalized Boundaries of the Plastic Zone 

      Zeev Zimerman; Betzalel Avitzur (The American Society of Mechanical Engineers (ASME), 1970)
      The boundaries of the plastic zone in radial flow through conical converging dies are analyzed. The assumed boundaries are generalized, so that their shape and location are functions of the ...

    • Effect of Surface Slope on Shear Angle in Metal Cutting 

      G. Boothroyd (The American Society of Mechanical Engineers (ASME), 1970)
      The effect of the work surface slope, or the rate of change of undeformed chip thickness, on the shear angle in metal cutting is studied experimentally. It is shown that the results of ...

    • Analysis of Tool Wear: Part II: Applications of Flank Wear Models 

      A. Bhattacharyya; A. Ghosh; Inyong Ham (The American Society of Mechanical Engineers (ASME), 1970)
      For machining with cemented carbides and ceramics, a quantitative assessment of tool failure at the flank for establishing “limit criterion” is necessary. The arbitrarily chosen flank wear limit ...

    • Mechanics of Gear Hobbing 

      A. Bhattacharyya; S. R. Deb (The American Society of Mechanical Engineers (ASME), 1970)
      The exacting demands for producing accurate gears make it necessary to determine the cutting forces coming on the hob-shaft which is the weakest element subjected to severe bending and torsion. ...

    • Deformation in Orthogonal Cutting 

      S. Ramalingam (The American Society of Mechanical Engineers (ASME), 1970)
