Composites are very difficult form a machining due to non-homogeneous and anisotropic environment and it require unique cutting tools. This piece of research investigates-GFRP composite round machinability performance in CNC machining of UD-GFRP composite round rods under wet condition as well as cryogenic machining. This investigation considered the Poly- crystalline diamond tool for both group of samples machining. The responses which measure the machining quality are: the tool wear, quality of the surface and forces generated at various stages of inputs given to the machining of UD-GFRP composite. The optimization technique i.e.Taguchi L9 orthogonal array is used for examinations and find out the targeted. The design includes three independent variables at three levels. The pro- posed process control independent variables are: rate of feed of tool, spindle speed or velocity of cutting and operation depth tool in the work. The investigation aims to establish the process control by studying the relationship between level of inputs and degree of responses to identify the optimal level of process inputs for acceptable surface quality with minimum tool wear and cutting force.
