Evaluation of Thin Wall Milling Ability Using Disc Cutters

et al. 2023

In some cases, industrial practice requires the production of walls or parts with a thickness of less than one millimeter from a metal workpiece. Such parts or walls can be made by milling using disc cutters. This machining method can lead to the generation of residual stresses that determine the appearance of a form deviation characterized by bending the part or the thin wall. To evaluate the suitability of a metallic material for the manufacturing of thin walls by milling with disc cutters, different factors capable of exerting influence on the deviation generated by the residual deformation of the walls were taken into account. A test sample and an experimental research program were designed for the purpose of obtaining an empirical mathematical model. The empirical mathematical model highlights the magnitude of the influence exerted by different input factors on the disc cutter milling process regarding the size of the deviation from the form, and the correct position of the wall or thin part, in the case of a test sample workpiece made of an aluminum alloy. Input factors considered were cutting speed, feed rate, cutter thickness, wall or part thickness, thin wall length, and height. To rank the input factors whose increase leads to an increase in shape deviation, the values of the exponents attached to the factors in question in the empirical mathematical model of the power-type function were taken into account. It was found that the values of the exponents are in the order 0.782 > 0.319 > 0.169 for wall height, feed rate, and wall width, respectively. It was thus established that the strongest influence on the residual deformation of the thin wall is exerted by its height.

“…In the aerospace field, many machineries, transportations and structural components have to be subjected to complex dynamic stress as the industry quickly develops [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. What is most important is that lots of structures and mechanical components are constantly working in a vibrating state or even in the resonant condition, and this is particularly the case in the aeronautical field.…”

It has been previously noted that the development of aerospace material technology and breakthroughs are inseparable when obtaining great achievements in the aerospace industry. Materials are the basis and precursor of modern high technology and industry. As one of the most powerful aluminium alloys, 7050 is widely used in the aerospace field. In this manuscript, the vibration fatigue behaviour of aircraft aluminium alloy 7050 is studied based on experiments. A vibration fatigue experiment and the traditional fatigue testing of aluminium alloy 7050 were performed. We found that there was an extreme difference between the vibration fatigue and the traditional fatigue curves. In addition, the experimental end criteria for the vibration fatigue experiment of aluminium alloy 7050 was obtained from the acceleration reduction and the frequency reduction value. For the acceleration experimental end criterion, 2% was the acceleration reduction value for the vibration fatigue experimental end criteria of aluminium alloy 7050. For the frequency experimental end criterion, 2% was the frequency reduction value for the vibration fatigue experimental end criteria of aluminium alloy 7050.

Aerospace parts have the characteristics of complex shape and high machining accuracy, the machining processes of which is complicated and diverse. Numerous special tooling fixtures need to be designed to ensure the smooth implementation of the machining process. In particular, the cabins of the aircraft have thin-walled, weakly rigid, complex, and special-shaped curved structures, the clamping alignment of which is difficult because of a great deal of human influence and poor versatility. In response to the above problems, off-machine clamping technology was investigated, which supports the non-intervention processing of flexible production lines. Then, a scheme suitable for accurate transmission of benchmarks was proposed. A cabin’s mathematical model of casting clamping force analysis was established. Immediately afterwards, the optimization of clamping project was realized by a finite element analysis method based on clamping force and deformation control. The off-machine clamping scheme was designed to realize rapid positioning and accurate datum transmission between flexible tooling and parts, flexible tooling, and equipment. Finally, the designed scheme was implemented through a case to verify its feasibility.
