  Machining Performance and Tool Wear Behaviour of 3D Carbon Fibre-Reinforced Silicon Carbide Composites

  By Santosh Kumar. K, V. Ajay Kumar, T. Nagaveni, K. Saraswathamma

  Abstract: 3D Cf/SiC composites, consisting of carbon fibers reinforced with silicon carbide are increasingly used in aerospace and defence due to their excellent mechanical properties and high-temperature strength. However, their heterogeneous, anisotropic, and abrasive nature makes them difficult to machine, resulting in accelerated tool degradation and poor surface integrity. This study explores the dry milling performance of 3D Cf/SiC composites using polycrystalline diamond (PCD) and cubic boron nitride (CBN) cutting tools. …
