This paper reports the experimental investigation of high speed drilling of glass fiber reinforced composite. The relevance of this study is that it establishes empirical relations as a function of machining variables, relevant to analyse the machinability of glass fiber reinforced composite. The response functions considered delamination factor at entry and exit and the machining variables are point angle, cutting speed and feed rate. Experiments are conducted on the basis of response surface methodology technique. Empirical models correlating process variables and their interactions with the said response functions have been established. The models developed reveal that point angle is the most significant parameter. These models can be used for selecting the values of process variables to get the desired values of response parameters.
