...Liviu Nistor; Adriana Neag; Ionut Marian; Dan Frunza In this paper, the cold simultaneous toothing of spur gears has been investigated. This method can be described as a press-rolling process. The influence of gear geometry such as teeth number and the deformation mechanism was investigated by 3D...

... research and development activities in the area of plastic forming of metals and will be a valuable resource for our colleagues and friends. A paper on “Using Servo-Drive Presses to Determine the Effect of Blank Holder Pressure on Temperature Change in Warm Forming of Sheet” is presented by Altan’s...

..., the material models required to obtain accurate results, and the advanced stamping presses and approaches for shaping modern steel sheet materials into desired shapes. Present research trends are summarized, which point to further developmental possibilities. Within the next decade, it is predicted...

.... The interference produced by penetration is much more when compared to interference generated during full machining of thread. Thus, there is a pressing need to analyze interference during penetration. So, this study evaluates different applied penetration strategies and the level of interference produced. Further...

.... This process begins with unfolding the part and constructing the required part geometry with a series of forming operations. In this study, the same process steps have been used to automate the progressive die design for a given part and stamping press capacity. Therefore, the strip layout already considers...

... to their limited formability at room temperature, forming needs to take place at elevated temperatures and mostly under nonisothermal conditions. In this study, nonisothermal deep drawing process using aluminum and magnesium alloys was investigated using a servo motor driven press and a heated tool set. Using...

...R. Luri; C. J. Luis; J. León; M. A. Sebastian Equal channel angular extrusion or pressing (ECAE or ECAP) is a process used in order to impart severe plastic deformations to processed materials with the aim of improving their mechanical properties by reducing the grain size. The grain size reduction...
