A review on drilling of FML stacks with conventional and unconventional processing methods under different conditions

Fiber and metal materials used in Fiber Metal Laminate (FML) have different machinability properties due to their different structures. This case has made it a research topic to obtain good hole quality in these materials. A good match between the parameters used is required for the machinability of FML. Traditional and nontraditional machining methods in the machining of FML in this article were investigated and a comprehensive review regarding the machining parameters and hole quality were conducted. Considering the methods and parameters used, the defects occurring in the holes (delamination, hole size and circularity, surface roughness, etc.) were determined and the most suitable processing methods and parameters were picked in order to minimize these defects. As a result, the most suitable machining method and optimum cutting parameters for a better hole quality in FML machinability are determined, and it is aimed that this study will be beneficial to scientific and industrial societies.
