Abstract

Vibration dampening in machining processes is an important part of a machine being precise, low maintenance, and long lasting. Being able to utilize dampening materials in the design of machinery in existing structural tubing could allow designers to isolate vibration sources from critical components more effectively than with current methods. The purpose of this research was to show and analyze the effect of dampening materials undergoing specific machining vibration. An experiment was designed that used hollow columns both with and without dampening material and a CNC Mill to generate different types of vibration. These vibrations are detected using accelerometers at the top and bottom of the structure. By creating a variable matrix testing different viscosity dampening materials, different spindle speed, and different depth of cut, vibration with different frequency and amplitude was tested. By analyzing the characteristics of the vibration transmitted by the structure without a dampening material compared to that same vibration with a dampening material, a conclusion was made as to whether these materials dampen machining vibration.
