A Determination Method of Cutting Coefficients in Ball End Milling Forces Model
International Journal of Automation Technology, 2013 Cutting force is very important in predicting machining error, surface properties, and chatter vibration. Cutting process simulators based on cutting force models for ball end mill operations have been developed so far by a lot of researcher. This paper describes a new approach for determining cutting coefficients, which are indispensable in predicting

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Estimation of Cutting Force Model Coefficients with Regularized Inverse Problem
Advances in Manufacturing Science and Technology, 2013 In this paper, a method for estimation of cutting force model coefficients is proposed. The method makes use of regularized total least squares to identify the cutting forces from the measured acceleration signals and the frequency response function (FRF) matrix.
