Abstract: This paper presents a fundamental study for the characterization of formability in bending/hemming, or “bendability/hemmability,” of automotive aluminum alloys. Based on the strain/stress nature of ...

Abstract: Fixtures are used to locate and hold workpieces during manufacturing. Because workpiece surface errors and fixture set-up errors (called source errors) always exist, the fixtured workpiece will ...

Abstract: This paper presents algorithms for workpiece positioning analysis under locating errors. Workpiece constraint equations are first constructed using the method of homogenous coordinate transformation. ...

Abstract: Hemming is a manufacturing process of folding a panel onto itself or another sheet. Quality of hemming is characterized by geometry and formability. This paper presents a response surface study ...

Abstract: Dimensional variation in assembled products directly affects product performance. To reduce dimensional variation, it is necessary that an assembly be robust. A robust assembly is less sensitive ...

Abstract: During process planning stage in an automotive vehicle development process (VDP), one of the tasks is to select tools such as weldguns and fixtures from large tool libraries and assign them ...
