Tool Materials and Tool Wear

Chapter

Machining of fiber-reinforced polymers (FRPs) is a challenging process from the point of cutting tool requirements. Unlike metal cutting where plastic deformation is the predominant cause of chip formation, the cutting of FRPs takes place by compression shearing and fracture of the fiber reinforcement and matrix. This puts stringent requirements on the cutting edge geometry and material. A sharp cutting edge and large positive rake angle are often required to facilitate clean shaving of the fibers, and a tool material with high hardness and toughness is required to resist the abrasiveness of the fibers and the intermittent loads generated by their fracture. Only a limited choice of tool materials that can meet these demands is available. This chapter is an overview of cutting tool materials and their wear characteristics in machining FRPs. The types of tool wear, tool wear measurement, and the controlling wear mechanisms are discussed. Recommendations for good practices in selecting...
