Tyler Grimm - Automotive Engineering Graduate Research Assistant


My interest in automotive manufacturing started at an early age. Working on cars with my dad allowed me to dissect the many systems within them and learn how they worked. In pursuing this interest, I attended college at Penn State Behrend for a bachelor’s degree in mechanical engineering. I quickly joined a manufacturing research group led by Dr. John Roth, an expert in this field. Over the next few years, my interest turned into a passion, and I was able to experience the remarkable influence academic research can have on industry. The research I am now conducting at Clemson University aims to improve advanced manufacturing processes for rapid implementation into domestic industries.

Featured Research

Incremental Forming

Incremental forming is an advanced manufacturing process capable of rapid prototyping of sheet metal shapes. These logos of the major automotive OEM’s were each formed in less than 20 minutes, without any dedicated dies. Whether it’s a desk ornament or an experimental panel on a concept car, incremental forming provides an excellent solution.


When machining freeform surfaces, geometric errors known as scallops are inevitably formed. Traditional toolpaths, which form these scallops in repetitive patterns, can easily produce a maximum scallop height. We’ve developed an algorithm to randomly generate toolpaths, while still maintaining a specified tolerance. With a unique surface finish, this process has an aesthetic appeal in addition to industrial advantages.


This highly exploratory research was recently presented at Automotive Circle conference Insight @ BMW Manufacturing Co., LLC. The goal of this project was to incrementally form tailor welded blanks created by only using friction element welding. What we discovered was that the fundamental nature of the incremental forming process made it very difficult to successfully form deep geometries.
