Even if turning is a small portion of what this machine is used for it would have other benefits as well such as higher drawbar force. I remember a mention of how Brother once offered a...

    3D metrology

    How about "scanning white light interferometry", a non-contact method of measuring surface finishes. It would take knowledge of optics and image processing but should be achievable over a semester of work. You would need to make a mounting brackets during your internship to hold the optical...

    What are these Doosan coolant gun/washwand/air blow nozzle options?

    I use a Kurita SP100 spray gun, it's what Japanese machine tool builders such as Makino use. It took a while to find it but it feels heavy and well built. https://us.misumi-ec.com/vona2/detail/221000613487/?HissuCode=SP100 Another suggestion is to hang the coolant hose and nozzle inside the...
