Double Sided Incremental Forming (DSIF) Machine at Macro-scale

Prototype of Gen-1 macro-scale DSIF machine

Schematic

The first generation of macro-scale DSIF machine has been built in the AMPL at NU. Two opposite x-y-z linear stages were designed to hold two forming tools. 

In order to increase the forming stiffness, accuracy and flexibility, the second generation of the macro-scale DSIF machine has been built in the AMPL. A novel configuration of the parallel kinematic mechanism (named Tri-pyramid Robot) was designed for the new machine. Also, an adaptive clamping system was developed to implement a higher forming flexibility corresponding to the different toolpath strategies.

A novel DSIF desktop machine has been built for DSIF at meso scale. The new desktop machine with meso-scale motions was developed based on our design of the Tri-pyramid Robot.
