Despite the fact that Titanium material has been considered as difficult to cut material, its usage has been increasing day by day in all engineering sectors; wherever criticality is encountered. Many studies are going on in view of increasing tool life at high cutting speed to improve productivity. In this study, attempt has been made to see the effect of iron as a partial substitution  along ...

The actual significance of any definition of toughness behaviour of carbide tools depends on the existence of an interrelation between the auality as defined and the occurrence of chiuninn and uremature failure in cuttin?. V'hile at ?resent there is no ademate analvsis available and the existing classifications do not even nrovide a ?ualitatiVc. indication for tool choice, one first has to eval...

Transmitter release at Cs(+)-loaded autaptic terminals was selectively activated by the subthreshold concentration of external K+, and Ca(2+) channel types and transmitter pools involved in synchronous and asynchronous exocytosis were studied. When a neuron was depolarized to +30 mV by applying a current through a pipette containing Cs(+) for >30 s, a rapid external K+ jump to 3.75-10 mM, other...

en-ac 48000 aluminum alloy is an important alloy in industries. machining of this alloy is of vital importance due to built-up edge and tool wear. three type of cutting tools including coated carbide (cd1810), uncoated carbide (h10), and polycrystalline diamond (cd10) have been used in this research in this paper, the effect of machining parameters including lubricant emulsion percentage and to...

Microlubrication minimizes the exposure of metal working fluids (MWFs) leading to an economical, safer and healthy workplace environment. In this study vegetable based lubricant is used to conduct wear analysis during end milling AISI 1018 steel using microlubrication. Solid carbide cutting tool was used with varying cutting speed and feed rate having a constant depth of cut. A full factorial e...

Background The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) is a generic measure of functional impairment and disability but to date no studies have reported its applicability in population Syrian refugees. Aims aim this study was explore the psychometric properties factor structure Arabic version WHODAS among refugees Jordanian refugee camp setting. tool used as pa...

In recent years, mold manufacturers have had to meet growing demand for high precision molds, low cost and short delivery time due to the miniaturization of finished products, price competition with overseas companies, and reduced model cycles. In line with these market changes, users have been gradually inclined to shift their machining methods applied to key mold parts (made of hardened steel...

The tool wear is an unavoidable phenomenon when using coated carbide tools during hard turning of hardened steels. This   work focuses on the prediction of tool wear using regression analysis and artificial neural network (ANN).The work piece taken into consideration is AISI4140 steel hardened to 47 HRC. The models are developed from the results of experiments, which are carried out based on De...

BACKGROUND The Kessler Psychological Distress Scale has been widely used in assessing psychological distress among general and clinical populations from different cultural backgrounds. To our knowledge, however, researchers have not yet validated any translated versions in Arabic. The purpose of this study was to test the reliability and validity of Arabic translations of the ten item (K10) and...

Cutting fluids, usually in the form of a liquid, are applied to the chip formation zone in order to improve the cutting conditions. Cutting fluid can be expensive and represents a biological and environmental hazard that requires proper recycling and disposal, thus adding to the cost of the machining operation. For these reasons dry cutting or dry machining has become an increasingly important ...
