Abstract:

Due to superior mechanical properties with lower weight compared to metals, there is an extended use of Carbon Fiber Reinforced Polymer (CFRP) and hence requires efficient machining solutions. For high quality surface roughness and to remove excess material, milling is one of the most practical machining techniques. Optimization of end milling parameters with multiple performance characteristics is done by a combination of Grey Relational Analysis and Taguchi design with L18 orthogonal array. Milling operation is performed on a vertical milling machine. The four input parameters considered for this investigation are milling strategy, feed rate, spindle speed and depth of cut. Machining force and delamination factor are selected as output performance parameters. It is observed that the largest value of GRG is for up milling, spindle speed of 1000rpm; feed rate of 70mm/min and depth of cut 0.2mm. Depth of cut and feed rate are found to the two most dominating factors
