Manufacturing System Laboratory

The manufacturing system lab includes MDH Machine Shop and Computer Aided Manufacturing (CAM) machine shop in Oliver Hall. MDH machine shop has five (5) Jet lathes (model GHP 1340), one (1) Enco lathe, and five Jet Vertical Mills (model JM2). CAM machine shop in Oliver Hall has one (1) HAAS CNC machine center (model VF4), one (1) South Bend lathe,and  one (1) Bridgeport vertical mill. This manufacturing system lab provides students with hands-on experience with various manufacturing processes for teaching purposes and enables  faculty and students to fabricate various components for senior design projects and other student projects. In addition, the lab provides faculty and students the  opportunities to conduct  experimental investigations of machinability of newly developed materials and performance of innovatively designed cutting tools.

Mechatronics Laboratory

Mechatronics lab is a teaching lab in Department of Aerospace and Mechanical Engineering. Mechatronics refers to the synergistic integration of precision mechanical structure and motion, electronic control, and system concepts in the design of industrial products and processes. We have autonomous mobile robots, Programmable Logic Control (PLC) Systems, and industrial robots. By using these mechatronics systems we give the students the opportunities to get hands-on experience and prepare students to be able to design and fabricate electro-mechanical systems and get industrial positions and/or succeed in future graduate studies.

Laser Peening Laboratory

Laser Peening is an emerging technology to improve the durability of precision metal components ranging from turbine blades and transmission gears to medical implants. The laboratory consists of a 1064 nm infrared pulsed laser, target positioning table, and associated optics. The lab is used to perform experiments involving laser-induced residual stress fields in precision metal components, with the intent to extend the fatigue life cycles. The facility is operated in collaborative research projects with the U.S. Air Force Research Laboratory. A student research group at Parks College has been formed to design and conduct computational and experimental research in laser peening.
