Zahner


Research and Development Intern - May to August 2019

I worked at Zahner to develop a way to crimp wall studs into curves to hold panels that skin buildings. The crimping device was modeled off of the curveatrack crimping tool. Using an input surface in Rhino, a Grasshopper program split up the surface into a set of curves of the bent studs.

The locations are collected into an excel file that a python program reads and sends into a Vention one axis robot. The robot then moves the stud according to the crimp locations and pauses to allow the stud to be crimped.

Modeled in SolidWorks, Rhino, and Grasshopper.













Model of desired structure.





















Crimping device modeled in SolidWorks.

























When the structure’s Rhino model is input into Grasshopper, the program I created calculates the length of each stud needed, the number of crimps, and how far apart each crimp must be to obtain the desired curvature for each stud.














These values are input into a Python program to control a one-axis Vention robot and move the stud at precise distances.
