A New Thrust Force Model for Drilling Process [PDF]

Journal of Production Engineering, 2010
This paper presents a new model for drilling process. The key to the model is the decomposition of the drilling process. The thrust force acting on drill is the sum of thre components: the cutting component, the thrust force attributed to ploughing at the chisel edge and the thrust force resulting from friction at the margin. The thrust study has shown

Electrode and Microstructure Dependence of Oxygen Diffusion in Ferroelectric Hafnium Zirconium Oxide Thin Films

Advanced Functional Materials, EarlyView.
Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.
