Dry Machining of Carbon Fiber Reinforced Plastic Composite by Rotary Ultrasonic Machining: Effects of Machining Variables

Abstract

Rotary ultrasonic machining (RUM) has been used to drill holes in brittle, ductile, and composite materials. However, all these experiments were conducted with help of water or oil based coolant. This paper presents an experimental study on RUM of carbon fiber reinforced plastic (CFRP) composite using cold air as coolant. It reports effects of machining variables (ultrasonic power, spindle speed, and feedrate) on outputs (cutting force, torque, surface roughness, and burning) in RUM of CFRP using vortex-tube (VT) generated cold air as coolant.
