High speed machining of the thin-walled aircraft constructions

Abstract: ) -Szel-Tech Szeliga Grzegorz; dr inż. Edward Rejman (erejman@prz.edu.pl), dr inż. Robert Smusz (robsmusz@prz.edu.pl) - Politechnika Rzeszowska im. Ignacego Łuka-siewicza Przedstawiono strategię obróbki przedmiotów cienkościen-nych, która stwarza szereg problemów technologicznych związanych ze zmianą kształtów i wymiarów przedmiotu obrabianego, oraz sposoby przeciwdziałania drganiom podczas obróbki skrawaniem, aby nie następowało pogorszenie struktury geometrycznej powierzchni obrabianej -chropowatość powierzc… Show more

“…The authors of the paper [24] presented the possibility of using an optical method to measure the deformation of thin-walled elements. In their development, they made an aircraft element from aluminum alloy 7075 and measured the deformation using a GOM machine.…”

“…Thin-walled constructions are increasingly used in various fields of industry, allowing to obtain monolithic structures that eliminate the need to perform assembly operations from multiple components. The advantages that give the ability to create structures made of thin-walled parts are difficulties in their implementation related to deformation under the influence of cutting forces resulting in deterioration of the surface quality, permanent deformation of the element and difficulties or impossibility to assemble [ 1 , 2 , 3 ].…”

“…The use of HSM (high-speed machining) allows for the simultaneous reduction of the cutting force components, which is very important when machining thin-walled workpieces, minimizing their deformation and at the same time obtaining a good quality of the treated surface. In addition, this treatment on the example of Bałoń et al tests gives the possibility of reducing the machining time four times compared to conventional machining [ 2 , 4 ].…”

“…The choice of an optimum thin-walled element machining strategy mostly depends on the ratio between the machined wall height and its thickness. Due to the above, three cases can be identified [ 17 , 48 , 49 ]: low height to thickness ratio < 15:1—where separate milling of each wall side in non-overlapping passes is recommended; moderate height to thickness ratio < 30:1: milling on a constant level—alternate machining at a constant depth of cut a p of both side walls, also in non-overlapping passes; milling at a difference of levels—alternate milling of both side walls with non-overlapping levels between consecutive passes; the depth of cut a p at the first pass should be a p /2; high height to thickness ratio > 30:1—Where it is recommended to change the sides and apply the “christmas tree” routine in order to achieve the wall thickness setpoint in stages. …”
