This article presents the results of a study investigating feed forces in milling processes for glass and carbon fiber-reinforced plastics. The forces are measured in both conventional and climb milling. The novelty of this article is use the feed forces values as signals for recurrence analysis. Recurrence quantifications obtained in different types of milling for the two different composite materials are plotted. 3D surface topography maps after conventional and climb milling are also presented. The results show that the use of climb milling produces lower feed force values for both types of composite materials. The milling of composites with glass fibers results in lower feed force values and better surface quality. Increased feed per revolution and cutting speed (in range 50–300 m/min) results in higher feed force values. It is also shown that the recurrence quantifications such as determinism (DET), entropy (ENT), laminarity (LAM), trapping time (TT), recurrence time of 1st type (T1), and clustering coefficient (CC) depend on the type of machining, composite material and technological parameters. The work extends the existing research in the use of recurrence methods, because the current research only concerned conventional milling.
