Titanium and its alloys have found wide application in the aerospace, biomedical and automotive industries owing to their good strength-to-weight ratio and high corrosion resistance. However, these alloys have very poor machinability, which is attributed to their inherent high strength maintained at elevated temperature and low thermal conductivity

Titanium alloys are widely known as difficult to cut materials, especially at higher cutting speeds, due to their several inherent properties. Among all titanium alloys, Ti-6Al-4V is most widely used, so it has been chosen as the workpiece material in this study. Siekmann [1] suggested that machining of titanium and its alloys would always be a pro

Titanium alloys are used widely in the aerospace, chemical and ship building industry because of their superior mechanical properties, heat resistance and corrosion resistance. Titanium alloys, however, are materials that are extremely difficult to machine. During the machining of titanium alloy, tool wear progresses rapidly because of the high cut

Though classified as a group of “difficult-to-cut” material, titanium and its alloys are have wide applications in the aerospace industry owing to their unique high strength-weight ratio which is maintained at elevated temperatures and their exceptional corrosion resistance. In this work, experimental investigations of the influence of preheati

Hard machining, a frequently used term in today’s machine tool industries, refers to the machining of material with a hardness value over 45 HRC. The concept of hard machining was developed in 80s; however, the prevalent industrial implementation of hard part machining was adopted during the last decade [1]. Advantages in hard machining incorpora

Chatter is an unwanted but sometimes unavoidable phenomenon in machining. The term defines the self-excited violent relative dynamic motion between the cutting tool and workpiece. Nakagawa et al. [1] stated it is meant as a problem has emerged during the endmilling of hardened steels. Campa et al. [2] described chatter as a dynamic problem at high

Nowadays, LCD is present everywhere in man-machine interfaces. It is used on various kind of instrument, such as Personal Digital Assistant (PDA), mobile phone, digital clock due to the superiority of display quality, relatively lower power consumption, small size, low weight, and also to its dimensional flexibility from less than one inch to as la

The medical service quality could be influenced by various factors such as medical care etiquettes, healthcare prac�titioners’ quality and healthcare practitioners’ advice. The implementation of Islamic healthcare services within Sha�riah-compliant hospital faces some challenges due to a lack of awareness, ethics and spirituality among heal

Mass media play a very signigicant role in politics. Mass media coverage of certain issues during political campign either increases or decreases the chance of gaining votes for any political parties and political leaders. This study was aimed at examining the Islam-related issues covered by the mainstream newspapers in Malaysia during the General

A laboratory study using a bench scale model of two units operation involving coagulation process with Moringa oleifera seeds extract as a coagulant and filtration process using hollow fibre microfiltration membrane, was adopted to treat Air Hitam Sanitary Landfill leachate in Puchong, Malaysia. The performance of the microfiltration membrane in pr
