“…Conventional milling strategies are prone to generate undercut while climb milling is usually related to overcut [37]. Symmetric tool paths are selected to compensate the effect of residual stresses in the part deformation [41] as well as to reduce in-process deflection. Similarly, particular tool paths may be designed to increase the part stiffness during the cutting operation [42].…”

Machining operations are chosen by aircraft manufacturers worldwide to process light aluminum alloys. This type of materials presents good characteristics in terms of weight and physicochemical properties, which combined with a low cost ratio making them irreplaceable in aircraft elements with a high structural commitment. Conventional machining processes such as drilling, milling and turning are widely used for aeronautical parts manufacturing. High quality requirements are usually demanded for these kinds of components but aluminum alloys may present some machinability issues, basically associated to the heat generated during the process. Among others, surface quality and geometrical deviations are highly influenced by the condition of the cutting-tool, its wear and the cutting parameters. Consequently, the understanding of the relationship among the process parameters, the quality features and the main wear mechanism is a key factor for the improvement in the productivity. In this chapter, the fundamental issues of drilling, milling and turning are addressed, dealing with the relationship between cutting parameters, wear phenomena and micro and macro geometrical deviations.

“…Jiang et al 11 indicated that the shrinking overlap coefficient K echoes with the decreasing influence of the deformation affected by the residual stress distribution, inevitably accompanied by the lowering material removal rate. Wu et al 12 investigated the milling deformation of aluminum alloy using the quasi-symmetric machining method. Yao et al 13 concluded that the maximum residual compressive stress and the depth of residual stress layer increased significantly after shot peening, and the residual stress and hardening distribution are very good.…”

This work describes the experimental investigation of the residual stress distribution in the square pocket milling of 2219 aluminum alloy. The results reveal that the axial depth of cut is the most important factor influencing the residual stress distribution of the machined pocket surface, and the more tensile stress states are found with the increase in axial cutting depth due to the thermal deformation. The dominant mechanical deformation at all spindle speeds tends to produce the compressive residual stress. Altered feed rate and radial depth of cut show little changes in the residual stress distributions and the average values. In addition, the pattern of residual stress distribution of the square pocket surface is dramatically changed and the more tensile stresses are produced as the milling operation further proceeds. From this investigation, it is suggested to shorten the cutting time by raising the cutting parameters such as the feed rate and the radial depth of cut to achieve the compressive stress and the good surface roughness.

“…At present, thin-walled structures are widely used in aerospace, civil, and automotive industries because of their exceptional strength and light weight [1]. However, local low-rigidity positions are especially vulnerable to vibrations and deformations when dynamic and static loads are applied [2].…”

Finite element (FE) models are utilized to investigate the influence of preload force and the stress stiffening on the dynamic characteristics of a thin-walled rectangular plate. An experimental platform system is established to obtain the dynamic characteristics of the specimen using the resonance method. Simulation and experimental results agree well with each other, which validates the effectiveness of the FE model. The results show that the preload force not only improves the overall dynamic performances of the thin-walled plate but also contributes to the local stiffness of the loading position because of the generation of stress.
