Processing and Mechanical Properties of the Workpiece in Machining of Long‐Fiber‐Reinforced Composites

Abstract

This work focuses on the analysis of the influence of mechanical properties of long fiber reinforced polymeric composite (LFRP) on machining operations. Experimental works covering main aspects of the machining process, such as tool selection, wear evolution, and cutting parameters were briefly reviewed. It can be concluded from this analysis that the composite properties strongly influence machining process. The selection of the tool, both cutting material and geometry, should be done depending on the type of composite family (carbon, glass, or aramid). This aspect also influences the evolution and mechanism of tool wear. On the other hand, numerical modeling is a useful tool to get a better knowledge of machining operations. Mechanisms of chip generation, cutting forces, and damage can be evaluated depending on the workpiece properties. Finite element approach involves modeling the mechanical behavior of the composite, material properties influence damage generation through the models formulation.
