Stamping Tutor

 

Overview

The Stamping Tutor helps students understand the relationship between sheet metal part designs and equired stamping stations. The student creates a design on a blank metal part and the tutor constructs the necessary animated stamping stations. The Tutor identifies design issues such as dissimilar features, closely spaced features, narrow cutouts and projections and bends.

It demonstrates how many stamping stations are needed for each design through both 2D and 3D animations. Then the student designs a part within an interactive environment, see Figure 3. Using an underlying internal representation of rules, the Tutor dynamically generates an animation of the proper number of moving stamping stations required to build the part. The Tutor also provides a non-intrusive critique explaining why the features chosen may result in an inefficient design. Currently, a cross-platform introduction, an interactive tutor, and 3D animations of stamping processes are available for distribution.
