Alum Success

"I chose to transfer to Lake Superior State University because of the personal attention I would receive. I did not want to attend a large university where I would be a number lost in the masses. The well-rounded curriculum allowed me to obtain my position at John Deere. Having a good balance of theory and hands-on knowledge is critical for my position and Lake State gave me a good foundation in these skills."

Project Description: Team Laser Control Solutions (LCS) is working alongside Mactech On-Site Machining Solutions to develop and test a real-time self leveling system for one of their specialty milling machines. Mactech is a small US company which specializes in on-site machining solutions for large industrial clients. One of their more specialized machines is the Large Diameter Facing Machine (LDFM), which is used to machine large diameter flanges (6’-18’) for the oil, marine, and power industries.

Currently the LDFM is operated by skilled machinists and can achieve a .015” tolerance on the flatness of the flange. The purpose of this project is to develop a real time monitoring system which will use a laser measurement device, custom controller, and servo motor to maintain the mill head within .005” of a pre-determined plane. This will result in much tighter machining tolerances and require almost no operator input. Some of the challenges that LCS will face are the vibrations and heat that the LDFM produces during machining. Due to the small tolerance that is to be held any amount of vibrations or thermal expansion can affect the measurement system. Through testing data and a well-designed control system LCS will be able to conquer these challenges.
