چکیده
Currently, the standard material used for micro end mill tooling is sintered tungsten carbide with a cobalt binder. Its brittle nature coupled with the micro-scaled cutting features of the end mills often result in rapid tool degradation. Tool life and cutting performance can be significantly improved using a thin nanocrystalline diamond (NCD) coating. The high hardness (~90 GPa), low coefficient of friction (~0.2), and chemical inertness of diamond help reduce tool wear, adhesion of workpiece material, and overall cutting and thrust forces. This study measures the performance of hot-filament chemical vapor deposited (HF-CVD) diamond coatings on micro end mills. Tool performance is evaluated by dry milling full-width channels in 6061-T6 aluminum.

Evidence for a persistent microbial seed bank throughout the global ocean.
Do bacterial taxa demonstrate clear endemism, like macroorganisms, or can one site's bacterial community recapture the total phylogenetic diversity of the world's oceans? Here we compare a deep bacterial community characterization from one site in the English Channel (L4-DeepSeq) with 356 datasets from the International Census of Marine Microbes (ICoMM) taken from around the globe (ranging from...

متن کاملFast chaotic optimization algorithm based on locally averaged strategy and multifold chaotic attractor
Recently, chaos theory has been used in the development of novel techniques for global optimization, and particularly, in the specification of chaos optimization algorithms (COAs) based on the use of numerical sequences generated by means of chaotic map. In this paper, we present an improved chaotic optimization algorithm using a new two-dimensional discrete multifold mapping for optimizing non...
متن کاملA New RSTB Invariant Image Template Matching Based on Log-Spectrum and Modified ICA
Template matching is a widely used technique in many of image processing and machine vision applications. In this paper we propose a new as well as a fast and reliable template matching algorithm which is invariant to Rotation, Scale, Translation and Brightness (RSTB) changes. For this purpose, we adopt the idea of ring projection transform (RPT) of image. In the proposed algorithm, two novel s...
متن کاملCan Wavelet Denoising Improve Motor Unit Potential Template Estimation?
Background: Electromyographic (EMG) signals obtained from a contracted muscle contain valuable information on its activity and health status. Much of this information lies in motor unit potentials (MUPs) of its motor units (MUs), collected during the muscle contraction. Hence, accurate estimation of a MUP template for each MU is crucial. Objective: To investigate the possibility of improv...
