Milling Examination on CFRP Composites for Automobile Structures.

Abstract

The CFRP is widely used in automobiles to reduce vehicle weight and give higher fuel efficiency due to greater strength to weight ratio. It should be needed to machine with accurate structure and integrity. The post curing process is necessary after machining the CFRP composite material to remove burr and delamination. The dual helix mill tool is used to perform slotting to eliminate burr formation and delamination. From the study there is no delamination is occurred when CFRP is machined at the cutting speed of 2500 rpm, feed rate of 600 mm/min and 1 mm depth of cut and also burr formation is highly reduced at this condition.
