Drilling quality can affect the properties of composite components; nevertheless, the evaluation on the drilling quality of carbon fiber-reinforced plastics (CFRP) mainly relies on experience and there is no mature theory that can be used to assess the drilling quality. This paper chose appropriate factors such as drilling parameters, conditions, and materials as the evaluation indexes and presented a comprehensive evaluation model. Further, the mathematical software MATLAB was used to fit and analyze the relationships of the drilling parameters and the evaluation sub-factors (delamination, surface roughness, and burrs). Then, the semi-empirical polynomial function of 3D level was established based on historical data of drilling experiments. In addition, the fitting result of the historical data indicates that the tool materials and the feed rate show the most significant influence on the drilling quality. In order to contrast the optimization results of the numerical examples, the drilling experiments have been conducted, and the results of the comprehensive evaluation were found to be in a good agreement with the experimental results through judging the quality of the holes.
