Abstract

At present, unidirectional fiber-reinforced composites (UD-FRC) are widely used. The machining of UD-FRC workpieces has some characteristic features. Thus, homogeneous materials cutting experience may not be used directly. One of the problems of UD-FRC machining is interfacial debonding between fibers and matrix at cutting wedge punching-in which results in surface quality deterioration. Therefore, prediction of the obtained surface quality is a vital problem. A rational selection of tool geometry results in debonding reduction. It is reasonable to apply numerical calculations methods as a pilot research stage. In the present research, the results of an SPH method modeling of UD-FRC workpiece machining are given. For the verification of the obtained results, experimental studies have been conducted. A qualitative agreement of modeling and experimental results proves that SPH method application is expedient for UD-FRC workpiece machining modeling.
