Abstract:The applications of ultrasonic vibrations for material removal processes exist predominantly in the area of vertical processing of hard and brittle materials. This is because the power generated by vertical vibrating oscillators generates the greatest direct penetration, in order to conduct material removal on workpieces by grains. However, for milling processes, vertical vibrating power has to be transformed into lateral (horizontal) vibration to produce the required horizontal cutting force. The objective of this study is to make use of ultrasonic lateral transformation theory to optimize processing efficiency, through the use of the finite element method for design and analysis of the milling tool. In addition, changes can be made to the existing vibrating system to generate best performance under consistent conditions, namely, using the same piezoelectric ceramics.
