Milling Induced Residual Stresses in Structural Parts out of Forged Aluminum Alloys
Machining operations of aluminum structural parts are typically carried out under high feeds and high cutting speeds. These cutting conditions exert thermal and mechanical loads on the workpiece, which cause changes in the subsurface material. Residual stresses belong to the machining induced changes and can lead to considerable rejection rates as a consequence of part distortion. Due to the si...
متن کاملA New Analytical Approach to Reconstruct Residual Stresses Due to Turning Process
A thin layer on the component surface can be found with high tensile residual stresses, due to turning operations, which can dangerously affect the fatigue performance of the component. In this paper an analytical approach is presented to reconstruct the residual stress field from a limited incomplete set of measurements. Airy stress function is used as the primary unknown to directly solve the...
متن کاملInfluence of Process Parameters on Residual Stresses Induced by Milling of Aluminum Alloy Using Taguchi’s Techniques
In this paper, the straight flute end-milling cutter used for machining of Al-Si-Mg-Fe alloy work pieces was investigated. The machining processes could induce residual stresses that enhance greatly the performance of the machined component. Machining residual stresses correlate very closely with the cutting parameters. In the experiments, the residual stress on the surface of workpiece was mea...
متن کاملDrying patterns: Sensitivity to residual stresses.
Volume alteration in solid materials is a common cause of material failure. Here we investigate the crack formation in thin elastic layers attached to a substrate. We show that small variations in the volume contraction and substrate restraint can produce widely different crack patterns ranging from spirals to complex hierarchical networks. The networks are formed when there is no prevailing gr...
متن کاملDetermination and Evaluation of Residual Stresses in Thick- Walled Cylinders Due to Autofrettage
Autofrettage is a treatment to introduce beneficial residual stresses into thick-walled cylinders to improve their performance under repeated loading by internal pressure. In the present investigation the residual stresses are measured and their effect was analysed and discussed. The experimental determination of the residual stress distribution was performed by the crack-compliance-method. The...
