Ultrasonic machining is a subtractive manufacturing process that removes material from the surface of a part through high frequency, low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles. Hence ultrasonic drilling will demonstrate strong competition to the conventional as well as the nonconventional machining processes for this composite material. The machined surface produced by ultrasonic machining is found to be free from any surface defects (heat affected zone, cracks, recast layer, etc.) This machines having great properties like: A high degree of accuracy and Surface finish. The effect of ‘parameters’ on machining performances can be studied and determined. Diagram shows some of the factors that affect the USM. The aim of the experiment described in the article was to verify, if the rotary ultrasonic machining is suitable for machining fiberglass and how does the technology and its parameters affects the delamination. USM is a versatile machining process as far as properties of materials are concerned. Another function used for the first time worldwide is the monitoring and tracking as well as of frequency and amplitude during the ongoing machining process. They are important because Introduction They can be used on all types of materials ranging from soft metals to hardened steels and hard nonmetallic materials such as Ultrasonic machining process is an abrasive process and material removal is purely mechanical. When very frequency vibrations are applied on to the tool, the tool is vibrating at a very high frequency. The experimental investigations take into account the effect of the key rotary ultrasonic machining input parameters including the ultrasonic power, spindle speed and feed rate on the output responses of cutting force, exit chipping, surface roughness, hole cylindricity and overcut errors, and surface integrity.
