He's not going to light up a tool sheet, but the guy just helps you win games".
However, non-uniformity in strain distribution is generated by the product geometry, tool-sheet contact conditions and material properties.
In the investigation, the causes of rough surface finish are investigated in detail, and the surface finish is refined by improving the contact condition at tool-sheet interface.
In this work, an improved E-DSIF process has been developed by combining the electrically-assisted forming technology, the double sided incremental forming (DSIF) and a newly designed slave tool force control device to ensure stable tool-sheet contact.
In the present work the tool path versatility has been explored by transferring some of the tool-sheet relative movements to the work piece by using a two-degree of freedom robotic manipulator with an aim to improve surface finish and achieve greater wall angles.
More recently, FEA has been shown to be an effective method of designing tooling for sheet forming processes.
In all experiments with angled tools, the sheet is clamped against the upper straight tool and free to move at the v-shaped tool, but due to unsheared material that counteracts the rotation of the free end, a F y somewhere between those calculated from shearing with parallel tools in one and two clamped configuration can be anticipated.
The tribological conditions between tools and sheet are the major factors affecting the product quality, forming limits and service life of tools in thin-walled titanium components warm forming.
Accurate prediction and controlling of springback is essential for the design of tools for sheet metal forming.
By combining nickel electroforming and the stereolithography process, press tools for sheet metal forming have been successfully produced.
For this reason, it is important to better understand the phenomena which occur at the interface between tool and sheet in this kind of process.
