Dr. Ngaile’s long-term goal is to contribute to the dramatic reduction of the use of toxins in metal forming lubricants.
At the undergraduate level, Dr. Ngaile teaches Modern Manufacturing Processes (MAE 495M) and Mechanical Engineering Design (MAE 416). In his manufacturing course, the students receive a hands-on introduction to modern manufacturing processes. Dr. Ngaile conveys his own experiences in manufacturing and takes the students on a tour of a manufacturing plant. In his design course, Dr. Ngaile places an emphasis on the general features of the design processes addressing issues that go beyond the design project being completed that semester.
Dr. Ngaile teaches Materials Processing by Deformation (MAE 731), which exposes the students to a wide range of metal forming processes including state-of-the-art techniques, and he teaches Applied Finite Element Method (MAE 589). In his applied finite element course, the focus is on developing the capability to solve a wide range of problems involving solids, thermal, fluids, and vibration. In MAE he collaborates with Dr. Fang.
Dr. Ngaile’s graduate students have a strong interest in solid mechanics. They gain experiences with numerical modeling of metal forming processes and hands-on experiences with machine design.
Outside of work, Dr. Ngaile enjoys to travel.
University of Dar Es Salaam
Dr. Ngaile is interested in design and manufacturing, tribology in manufacturing, modeling and optimization of manufacturing processes, material characterization, and finite element analysis. Dr. Ngaile is developing new formulations of metal forming lubricants, and is studying how to tailor metal forming processes to minimize the quantity of toxic-rich lubricants needed in these processes. Also, he is studying the influence of ultrasonic vibration on microforming processes.
