During the milling of Carbon Fiber Reinforced Polymer (CFRP), the cutting force is influenced by various process parameters. CFRP is a composite material composed of carbon fibers embedded in a polymer matrix, and its machining behavior is different from traditional metals. In milling Carbon Fiber Reinforced Polymer (CFRP), the cutting force components (Fx, Fy, and Fz) act in different directions relative to the machining process. CFRP is a composite material with anisotropic properties; the cutting forces may vary significantly depending on the orientation of the carbon fibers relative to the cutting tool. Careful consideration of the fiber orientation and proper tool path planning can help manage the cutting forces and achieve desired machining results with minimal damage to the CFRP workpiece. In CFRP milling, the Fy force is typically the dominant component since it includes the weight of the tool and the forces required to lift the material and move the tool through the workpiece. Reducing the Fy force is essential to minimize the risk of delamination and surface damage in CFRP components. The Fx and Fz forces are influenced by the factors mentioned earlier, such as cutting speed, feed rate, and depth of cut, tool geometry, fiber orientation, and machine rigidity. Present study has been done to optimize the process parameters during machining of CFRP by CNC end milling process. Three input process parameters namely cutting speed, feed and depth of cut were chosen as variables to study the process performance in terms of cutting force. Cutting forces have been examined by tool dynamometer.
