In-Situ Calibrated Modeling of Residual Stresses Induced in Machining under Various Cooling and Lubricating Environments

Residual Stresses - Measurement and Causes in Machining Processes

The fmctional behaviour of a machined component is substantially determiped by the physical state of its surface includinq the residual stress distribution ?ear ttc surface. The necessity to come to nore exact methods of layout for machined components compels one to take "surface integrity" as defined by W . Field /1/ and herewith residual stresses into consideration. Residual stresses dircccly...

In situ and induced stresses

Rock at depth is subjected to stresses resulting from the weight of the overlying strata and from locked in stresses of tectonic origin. When an opening is excavated in this rock, the stress field is locally disrupted and a new set of stresses are induced in the rock surrounding the opening. Knowledge of the magnitudes and directions of these in situ and induced stresses is an essential compone...

Numerical analysis of the tool wear effect in the machining induced residual stresses

Residual Stresses and Optimizing Machining Strategies for Aluminum Bars

R stresses have a major impact on the ability to fabricate dimensionally accurate machined components from aluminum wrought mill products. In addition, the ability to implement advanced assembly technologies such as determinant assembly, where parts are indexed to each other rather than to expensive assembly tooling, is compromised when the parts are not dimensionally accurate. An active resear...

Surface Finish and Residual Stresses Induced by Orthogonal Dry Machining of AA7075-T651

The surface finish was extensively studied in usual machining processes (turning, milling, and drilling). For these processes, the surface finish is strongly influenced by the cutting feed and the tool nose radius. However, a basic understanding of tool/surface finish interaction and residual stress generation has been lacking. This paper aims to investigate the surface finish and residual stre...
