Drilling force is the main factor affecting the drilling quality and tool wear of carbon fiber reinforced resin matrix composites (CFRP), selecting the appropriate process parameters can effectively control the drilling force, improve the drilling quality and tool life. In this paper, in order to accurately predict and effectively control the drilling force under the process of internal chip removal hole drilling: Firstly, based on the application of support vector regression (SVR) in data analysis, the theory of the prediction model of drilling force in CFRP is given; Secondly, on the basis of the above theories, the experiment of chip removal in CFRP is designed and completed, designed and completed the CFRP internal chip removal processing drilling experiment, it provides preparation for the solution of parameters in the subsequent model; Again, based on the above theoretical analysis and experimental data, under the premise of choosing the appropriate kernel function and loss function, the sequential minimum optimization (SMO) algorithm is applied to solve the unknown parameters in the model, to complete the construction of the SVR-based CFRP internal chip removal machining drilling force prediction model; Finally, using the constructed predictive model, it is predicted that when CFRP internal chip removal hole machining is studied, The relationship between cutting parameters (speed, feed), tool parameters (drill diameter, peak angle, relief angle) and suction parameters (negative pressure) and axial force.

Because of their high specific strength; carbon fiber reinforced plastics (CFRPs) are widely used in the aerospace industry. Metallization of CFRP by cold spraying as a surface modification method can improve the low thermal resistance and electrical conductivity of CFRP without the need for high heat input. Herein; we cold spray a Sn coating on cured CFRP substrates and examine the Sn/epoxy interface. The results suggest that the Sn coatings are successfully obtained at a gas temperature of 473 K and indicate no severe damage to the CFRP substrates. The stress and plastic strain distributions at the cross-section of the Sn/CFRP interface when a Sn particle is impacted onto the CFRP substrate are obtained using the finite element method.

“…So, there is a need to divide the cutting lip into small elements and then solve the elemental forces relation using integration. The associated formulation is discussed in detail in the available literature [29,[31][32][33]. It has been observed that cutting process is efficient towards the outer part of the cutting lip due to higher rake angle and cutting velocity, whereas cutting action is more dominated in the middle of the drill due to low cutting velocity and rake angle (negative in chisel edge), where i(ρ) is the inclination angle and can be represented using Eq.…”

Key composite made aerostructures such as fuselage inner walls, flap support fairings, empennage ribs, and the vertical fin ribs are comprised of non-vertical inclined and radial holes that join with other key metallic and non-metallic structures. Carbon fiber reinforced plastics (CFRP) are also used in the aerospace, automotive, marine, and sports-related applications due to their superior properties such as high strength to weight ratio, better fatigue, and high stiffness. CFRP drilling operation is different than the homogenous materials as the cutting-edge interacts with fiber and matrix simultaneously. Flank face of the tool rubs on the workpiece material and develops high frictional contact due to the elastic recovery of broken fibers. Lubrication during CFRP cutting can reduce the friction involved at tool-workpiece interface to enhance cutting performance. Dry cutting, cryogenic machining, and minimum quantity lubrication (MQL)-based strategies are termed as ecofriendly cooling/lubrication methods when machining high performance materials. The abrasive nature of carbon fiber is responsible of producing cutting forces which leads to different types of imperfections such as delamination, uncut fiber, fiber breakout, and fiber pullout. The integrity of CFRP drilled hole especially at the entry and exit of the hole plays a significant role towards the overall service life. The presented paper aims to characterize the interrelationships between hole inclination, lubrication/cooling methods, tool coating, and drill geometry with inclined hole bore surface quality and integrity during drilling of CFRP laminates. In dry cutting, thrust forces were found 2.38 times higher in the 30° inclination when compared with the reference 90° conventional inclination angle. Compressed air provided lowest increase (1.46 times) in the thrust forces for 30° inclination.
