Biography
Joël Rech is a professor at Centrale Lyon – ENISE. He heads a 25-strong research group working on the characterization and modeling of physical phenomena at the tool/material interface in cutting and superfinishing operations. He has made remarkable advances in the numerical modeling of surface integrity induced by cutting and polishing processes (residual stresses, roughness, microstructure) and in the modeling of tribological phenomena (friction, wear, etc.) of cutting tools. He has supervised 40 doctoral theses and published over 250 articles, which have been cited more than 9,000 times. He has an H-index of 53, is a member of CIRP and is on the editorial board of 6 international journals. He has been a member of over 50 scientific committees at international conferences. From 2014 to 2020, he was also Vice-President for Research at ENISE. Since 2022, he has been on Stanford University’s list of the world top 2% of scientists. He is also CEO and founder of the MISUTECH company, which publishes MISULAB, the first industrial software to predict the state of residual stresses induced by cutting operations.

38 Integrating machining conditions to calculate the fatigue life of a mechanical part
This article deals with the optimization of the fatigue life of machined surfaces. Since 2005, the LTDS laboratory a has developed a scientific method to predict the residual stress state generated by cutting operations on surfaces. This so-called “hybrid” modeling principle is based on equivalent thermomechanical loadings calibrated with experimental machining forces. This model has reached a high level of technological and scientific maturity. So, starting with the turning process, this methodology is now available as a software called MISULAB that predicts the three-dimensional residual stress fields on any kind of turned parts. The aim of this article is to show how three-dimensional residual stress fields on machined surfaces can be used in fatigue strength calculations of a shaft. The article shows how MISULAB can be connected to the NCode DesignLife software and how it can be used to maximize the fatigue life of a rotating shaft by optimizing machining conditions.
