Forming Limit Diagram, Void Analysis, Strain Distribution and Surface Roughness for SS430 Sheets During Multipoint Incremental Forming [PDF]
Single point incremental forming process is a most economical Die-less forming process. The major constraint of it is that it is a time consuming process. In this work, a new attempt was made in incremental forming process using Multipoint tool for SS430

The Forming Limit Diagram of 2A16 Aluminum Alloy Sheet Based on Hydraulic Bulging Test of Elliptical Die [PDF]
An elliptical die hydraulic bulging test was carried out to explore the forming performance of 2A16 aluminum alloy sheets during hydroforming. By using five groups of elliptical dies with ovality of 1.0, 0.9, 0.8, 0.6, and 0.4, the effects of different ...
