| Abstract Scope |
Narrow channels or ribs can be commonly found in sheet metal products. These narrow with high length-to-width aspect ratio channels are often integrated into sheet metal panels for functional features such as stiffeners or guide rails of various topographies, i.e. straight line or composite of curves. This work focused on development of Single Point Incremental Forming (SPIF) as a cost-efficient forming alternative to stamping or embossing of these features in short-series production. These channels present unique forming challenges, i.e. effects of channel spline geometry, varying cross section, end geometries on part formability and geometrical accuracy. SPIF of SS316L 0.5mm-thick narrow channels of three different geometries with maximum width of 20mm and its length-to-width aspect ratio lager than 5, i.e. 1) straight channel, 2) taper channel, and 3) curvature channel, was investigated. Based on the experimental results, 5mm dia. carbide tool and 0.1mm step-down size was recommended to optimize SPIF of these narrow channels. The effects of the different part features and their interactions with SPIF forming parameters on part formability and deviations are presented and analyzed for further development of die-less narrow channel forming for sheet metal industry. |
