Undesirable burrs are created in most of the machining processes. A burr is a plastically deformed material that remains attached at the workpiece edges after machining, and must be removed for making the parts to function effectively. The main objective of the present work is to explore the suitable condition to obtain minimum or negligible burr around the edge of a machined product at wet con...

Localization of each keratin isoform differs among epidermal layers. Proliferating basal cells synthesize keratin 14 (K14) and suprabasal cells express keratin 10 (K10) in normal skin. Notch signaling is essential for keratinocyte differentiation. Notch1 is expressed in all epidermal layers, Notch2 in the basal cell layer and Notch3 in basal cell and spinous cell layers in normal epidermis. It ...

In this paper a self-developed polycrystalline diamond coating was done on tungsten carbide (WC) tool insets by using simple thermal chemical vapor deposition technique. The growth of these films has been carried out at ~900 ºC temperature. as-grown the surface inserts have characterized Raman spectrometer and scanning electron microscope (SEM). morphological studies reveal that are high crysta...

BACKGROUND K1 and K2 are the main type II keratins in the suprabasal epidermis where each of them heterodimerizes with the type I keratin K10 to form intermediate filaments. In regions of the ears, tail, and soles of the mouse, only K2 is co-expressed with K10, suggesting that these keratins suffice to form a mechanically resilient cytoskeleton. OBJECTIVE To determine the effects of the suppr...

In recent years, coated cemented carbides have often been the first choice for a wide variety of tool inserts and applications. Its success as cutting material arises from unique combination wear resistance toughness, its ability to be formed into complex shapes. The structure obtained by sintering nanoparticle powders provides significant improvement in product properties, such higher speeds, ...

in this research, our attempt is to monitor tool wear through the chip formations, forces, and temperature of edge of drill while drilling in superalloy plate to optimizes effective parameters, which lead to facilitate machining process to, improved tool life, and enhance the productivity. in this study, inconel718 superalloy material, and cemented coated carbide tool was selected for investiga...
