  2010 AUG 24 - (VerticalNews.com) -- According to recent research published in the journal Cirp Annals - Manufacturing Technology, "A measure of product variety induced manufacturing complexity has been proposed based on the choices of assembly activities that operators make in serial, manual mixed-model assembly lines. In this paper we extend the complexity measure to assembly systems with parallel and hybrid configurations. ...read more

  2010 AUG 24 - (VerticalNews.com) -- According to a study from Dortmund, Germany, "A new roll-based process and machine for three-dimensional bending of profiles with symmetrical and asymmetrical cross-sections have been developed."

  "Compared to conventional processes like stretch bending, the advantage of the Torque Superposed Spatial (TSS) bending is the kinematic adjustment of the bending contour, leading to higher flexibility and cost efficiency, especially in small batch production. To define the spatial geometry of the workpiece, a torque is superposed to the bending moment," wrote S. Chatti and colleagues, Technical University ...read more

  2010 AUG 24 - (VerticalNews.com) -- According to recent research published in the journal Cirp Annals - Manufacturing Technology, "Due to the lack of coolant in dry machining processes, there is an increase of heat input into workpieces during the cutting process. As a result, an inhomogeneous temperature distribution occurs, which can lead to problems concerning compliance with critical tolerances, because of distortions of the workpiece. ...read more
