Pfefferkorn to investigate use of diamond coatings and modulation in drilling applications

The Wisconsin Alumni Research Foundation (WARF) has awarded Mechanical Engineering Associate Professor Frank Pfefferkorn two grants to investigate the use of diamond coatings and modulation-assisted drilling applications. 

Funded by both an Innovation and Economic Development Research Grant and a supplemental technology transfer research award from the UW Graduate School, the yearlong project will support two graduate students. They will work closely with NCD Technologies in Madison, Wisconsin, and M4 Sciences in West Lafayette, Indiana, to combine the benefits of nanocrystalline diamond coatings and modulation-assisted drilling to increase productivity without metalworking fluids. Pfefferkorn says that embracing diamond coatings and vibration or ultrasonic modulation could reduce manufacturing costs while also making the process greener by eliminating the need for environmentally hazardous fluids used in wet drilling.
