Abslracf In drilling of composite laminates, it is important to minimize or reduce wcmnces of delaminations. In particular, B peel-up delamination at entrance and poabdnt delamination at exit are common. Delaminations may be avoided by regulating the drill thrust force can be controlled by adjusting the feednte of tbe drill. Dynamics involved in drilling of composite laminates is time varying and nonlinear. lo this paper, a fopr logic model and conhml strategy are proposed. Simulation results show that the fuzzy model can deseribe the nonlinear time-varying proeess well. The fuzzy controller realizes a fast rise time and a tittle oversboot of drilling force.
