COMPOSITES MACHINING
is expanding rapidly due to their inherent advantages of durability, resistance to corrosion, and high strength-to- weight ratio. Difficulty of machining can vary greatly de- pending on the combinations of matrix material and fiber
reinforcements chosen. Composites are as varied as the matrix formulation, fiber type, fiber content, fiber orienta- tion, and build-up of the material.

Possible combinations and their machining character- istics, according to Kennametal’s Composite Machining Guide, include fiber reinforcement materials like carbon fiber/graphite fiber, glass fibers, ceramic fibers, polymer fibers, and tungsten fibers. Poly matrix materials include epoxy, phenolic, polymide, and polyetheretherketone (PEEK). Machin- ing characteristics of CFRP/CFRP and CFRP/metal materials are impacted by the abrasiveness of fibers, fiber size, fiber diameter, fiber length, volume of fiber percentage, and fiber layout, i.e. unidirectional or fabric weave. For example, fiber abrasiveness increases with strength and diameter. Short fibers tend to delaminate, as do unidirectional layered composites. Enhanced software is available that
increases the ability of manufacturing engineers to analyze, optimize, and document the CNC programming and machining process for advanced com- posites. For example, the latest release of Vericut CNC from CGTech (Irvine, CA) can simulate all types of CNC ma- chining of composites, including drilling and trimming, water jet cutting, riveting, mill/turn, and parallel kinematics. The release features several enhance- ments designed to increase workflow, enabling users to quickly access only the menu choices needed at the time. A new ribbon bar helps users find the functionality they need quickly and with minimal mouse clicks. At AeroDef Manufacturing 2017,
CGTech will showcase the steps needed to get from a CAD-designed composite part to CNC programs. Highlighted will be the implementation and use of machine-independent, off-
