A comparative study on conventional drilling and helical milling has been reported under the context of aircraft alloy hole making. The impacts these two different machining processes microstructures fatigue performance alloys have elaborated. Results show that both undergo more severe surface/subsurface plastic deformation comparing to process. Helical leads a longer coupon life compared for alloys. Al 2024-T3 is significantly than Ti-6Al-4V all conditions. use coolant generally produces...
The carbon fiber–reinforced plastics have gained considerable attention in the aerospace industry recent years. Drilling of plastic is relatively difficult with too much fiber delamination and pulling out entry exit holes. As an advanced hole-making technology, helical milling being developed machining plastic, which tool moves on a course to workpiece. Experiments were carried effects cutting parameters wear forces are analyzed, relation between hole quality also discussed. In order...
Abstract This paper reports an experimental investigation into joining mechanism and mechanical properties of carbon fiber reinforced polyphenylene sulfide (CF/PPS)‐AA7075 friction stir blind riveting (FSBR) joints made different structure rivets. Four types rivets were obtained by second machining the commercial rivet, corresponding FSBR test conducted. Penetration forces temperatures during penetration process collected. The joint quality, tensile shear strength, failure mode four...
Hole-making for Carbon Fiber Reinforced Plastics (CFRP)/Ti-6Al-4 V stacks is crucial the assembling strength of aircraft structure parts. This work carried out experimental helical milling (HM) with sustainable cooling/lubrication (dry, MQL and cryogenic) conditions. Cutting forces temperatures at CFRP layer, Ti-6Al-4 layer interface were obtained by a developed measuring system. The in machining cryogenic condition varied from −167 °C to −94 °C, which much lower than those dry maximum...
Laser surface pretreatment is an effective approach for improving the mechanical properties of adhesive joints. In case laser treatment carbon fibre reinforced polymer (CFRP), ultraviolet (UV) lasers and lower pulse fluence infrared (IR) are usually used to ensure quality. With respect efficiency as much possible, influence higher (12.7 J/cm2) IR parameters on CFRP/aluminium alloy hybrid joints were investigated in this study. Scanning electron microscopy (SEM), contact angle measurements,...
The aim of the present paper is to reveal influence different fiber orientations on tool wear evolution and mechanism. Side-milling experiments with large-diameter milling tools are conducted. A finite element (FE) cutting model carbon reinforced plastics (CFRP) established get insight into stress status at stages. results show that bring about distinct differences in extent, profile mechanism wear. Severer occurs when 45° 90° plies, followed by 0°, correspondingly, least obtained θ = 135°...
