On the Topology of Sheet Metal Parts
Abstract This paper analyzes the topological properties of sheet metal parts represented schematically (zero thickness, zero bend radii). Although such parts are usually non-manifold objects, the paper establishes a general topological invariant f = s + b + e + w v gnm + m regarding the number of facets, components, bends, free edges, welds, vertices holes and volumes, respectively. Correspondi...
متن کاملMultiple Fault Diagnosis for Sheet Metal Fixtures Using Designated Component Analysis
This paper presents a new approach to multiple fault diagnosis for sheet metal fixtures using designated component analysis (DCA). DCA first defines a set of patterns based on product/process information, then finds the significance of these patterns from the measurement data and maps them to a particular set of faults. Existing diagnostics methods has been mainly developed for rigid-body-based...

متن کاملAn Experimental Study of Springback of Bent Sheet Metal Parts
Bending is the uniform straining of material around a straight axis and is used commonly in various sheet metal industrial products. Since all materials have a finite modulus of elasticity, plastic deformation is followed by some elastic recovery when the load is removed. In bending processes this phenomenon is called springback. Springback occurs not only in flat sheets or plate, but also in b...
متن کاملOn planning immobilizing fixtures for three-dimensional polyhedral parts
We propose a simple three-dimensional modular xturing device and present an algorithm for enumerating all of the immobilizing xtures of a polyhedral object that can be achieved with this device and four friction-less contacts. Our approach is based on the second-order mobility theory of Rimon and Burdick 19, 20, 21].
