IMPACT OF PART MICROSTRUCTURE ON RESULTING SURFACE FINISH AFTER FINAL MACHINING

Machining is used ubiquitously in an enormous number of sectors. The surface finish resulting from machining operations is critical for performance attributes such as fatigue, wear, corrosion, etc. However, little is known about the influence of underlying microstructure on the resulting machined surface finish. This project would investigate the role of microstructure by systematically varying microstructures and developing a standardized methodology to measure surface roughness after machining. The project would be performed in close collaboration with John Deere, who would assist with experimental machining.

More Information

Very little literature exists in this area.

Grand Engineering Challenge: Not applicable

Student Preparation

Qualifications

Ideally, the student will have taken MTGN202.

Time Commitment

20 hours/month

Skills/Techniques Gained

The student will have the opportunity to learn heat treatment processes and microstructural characterization techniques. Unique to this project is the opportunity to utilize different possible methodologies for surface roughness including optical profilometry.

Mentoring Plan

At the beginning of the project, I will work with the student to develop their background in the project area, and we will develop a project plan together. I will also facilitate training for the student on the critical laboratory skills needed. As the project proceeds, I will work with the student to learn the research process including developing research questions and interpreting data. We will meet weekly.
