HPMA: High Performance Machining of Aluminum/Aerostructures

Our flagship course covers all aspects of high-performance machining of light alloys, specifically Aluminum, that is most susceptible to chatter and other vibration issues.

A general overview of state-of-the-art cutting technologies for high performance (HP) machining of aluminum is first covered. Once the basics and common ground are established by standard references provided for the class to pursue on their own the focus is on understanding the dynamic behavior of machining systems and how they influence cutting performance. Dynamic behavior is unique to every setup of machine, spindle, holder, cutting tool and workpiece and therefore needs to be considered independently of other machining technologies. Stability theory and dynamic behavior of cutting is presented. Cutting theory, frequency response and machine monitoring is presented with emphasis of predictive, diagnostic and corrective actions to vibration problems and improvements of poor quality of the machined part, e.g., bad surface finish or machining errors both dynamic and static. Complete coverage of dynamic behavior of tool and work piece will provide the student with a comprehensive and time-proven approach to maximizing the benefits of high-performance aluminum machining.
