Abstract. This paper provides an analysis of the Rigid Body Motion (RBM) in multi-stage Single Point Incremental Forming a cylindrical cup. The RBM is studied using Digital Image Correlation to track material each contour tool, resulting better understanding phenomenon than has been shown literature. study shows that highest Z-translations midpoint cone take place last contours stage, where the...

This paper describes single point micro incremental forming (SPMIF) applied to the fabrication of meso-scale shell structures. The authors have developed SPMIF without using any die and backing plate for flexible micro forming of miniature 3D products in a range of micro meters to sub-millimeters. A desk-top type of CNC milling machine was constructed as an experimental apparatus. Thin aluminum...

In this paper, we revisit the formability of tube expansion by single point incremental forming to account for material strain hardening and non-proportional loading paths that were not taken into consideration in a previously published analytical model process built upon rigid perfectly plastic material. The objective is provide new insight on reason why critical strains at failure are far sup...
