Ion beam milling has become a widespread specimen preparation technique for non-biological materials over the last two decades, particularly for cross-sectional and plan-view transmission electron microscope (TEM) specimens. The basic principle of ion milling involves bombarding a specimen with energetic ions or neutral atoms acclerated and formed into a tightly focused ion beam. Material is sp...

We report a study on the desorption properties, crystallography and chemical state of MgH2 and 1 mol% Nb2O5 ball-milled composites. Desorption temperatures of the composites decreased with increase of ball-milling time. Size of MgH2 crystallites decreased during ball-milling. Reduction of Nb2O5 after ball-milling was confirmed by tracing the chemical state of Nb and was further supported by TEM...

The recently available capability for the free-form milling of gears of various gear types and sizes — all within one manufacturing system — is becoming increasingly recognized as a flexible machining process for gears. This paper addresses the manufacturing and quality of gears made by free-form milling, with an added focus on the specific process properties of the parts. Finally, the potentia...

the purpose of this research is to use the machine vision, and combine with image registration •• mutual information••spatial transformation technique for the automatic wear measurement of Ti-Base coated milling. Provide on-line detecting the mill state during the milling processes in order to obtain a better surface quality. The experimental results indicated that the TiAlN-surface multilayer ...

The present work focuses on the mechanochemical preparation of industrially important β-cyclodextrin (CD) derivatives. Activated CDs have been reacted with nitrogen and sulfur nucleophiles using a planetary mill equipped with stainless steel, zirconia and glass milling tools of different sizes. It is shown that the milling frequency and the number as well as the size of the milling balls have a...

In the research presented here, the aim has been to develop a haptic milling simulator for surgical training of vertebral operations. One central goal has been to create a simulator that gives the user a realistic impression of contacts with, and milling of, a virtually represented bone tissue model. A new 6 degrees-of-freedom haptic algorithm for milling is implemented together with new 6 degr...

The present study investigates the preparation of the copper phthalocyanine pigment for inkjet printing inks. The pigment particle size distribution was measured with laser diffraction at different times of wet milling. Simultaneously, the absorbance spectra in a visible-near infrared spectral region of the corresponding diluted pigment dispersions were measured. At the beginning of the milling...

Ethanol and starch are the main products generated after processing of corn via dry grinding wet milling, respectively. Milling generates byproducts including stover, condensed distillers’ solubles, gluten meal, dried grains with solubles (DDGS), which sources valuable compounds for industry lignin, oil, protein, carotenoids, phenolic compounds. This manuscript reviews current research scenario...
