Cutting Force Estimation at NIST

National Institute for Standards and Technology

May 2021 - August 2021

Gaithersburg, MD

MATLAB, Linear Algebra and Calculus

The goal of this research was to develop a MATLAB program that processes inertial sensor input data with Fourier transforms and interpolation to estimate cutting forces experienced by machine tools, with the goal of applying the model in real-time machine health monitoring for large-scale manufacturing plants.

As an intern, I was responsible for this project under the mentorship of Dr. Greg Vogl.

I presented my cutting-force estimation model at the NIST Summer Undergraduate Research Fellowship Colloquium. The model showed reliable force estimates, while is detailed in the results below.

This project required overcoming the challenges of a virtual internship platform in order to collaborate with my mentor Dr. Vogl in developing this product. I learned about how to organize large scale programming projects and improve the efficiency of these processes through algorithms like Fast Fourier Transforms and interpolation.
