Brittle materials are hard to machine while maintaining the surface roughness desired. A brittle material will have little tendency to deform before it fractures when it is subjected to stress. Brittle material is also consider as a material which fails in tension rather than shear and has little or no evidence of plastic deformation before it fail

Chatter is an unwanted phenomenon in machining due to its adverse effects on the product quality, operation cost, machining accuracy, tool life, machine-tool bearings, and machine-tool life. The term defines the self-excited violent dynamic motion between the cutting tool and work piece [1]. During high speed machining of steel, large amount of ene

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

Machine tool chatter is an intensive type of vibration of the work-tool-fixture (WTF) system during metal cutting. It is caused by interaction of the instability of the chip formation process and natural frequencies of the individual components of the WTF system [1, 2, 3]. It was established earlier [1, 2] and confirmed by recent investigations [4]

The techniques of High Speed Machining (HSM), while still in an initial stage of wide acceptance, have already been proven in leading aircraft manufacturing plants [1]. HSM has been applied successfully to materials like magnesium and aluminum. Among the titanium alloys, Ti-6Al-4V being the most commonly used and it is the workhorse alloy of the ti

Chatter is an abnormal tool behaviour which it is one of the most critical problems in machining process and must be avoided to improve the dimensional accuracy and surface quality of the product [1]. The most critical limitation in machining productivity and part quality is the occurrence of the instability phenomenon called regenerative chatter [

Cutting tools are subjected to severe stress-strain conditions due to cutting forces, heat generated and vibrations caused during machining. These conditions affect the overall performance of the tool. Wear is the major concern in metal cutting and since it affects the productivity and dimensional accuracy of the machined part. Intensive chatter vi

Prior studies testing the relationship between initial public offering (IPO) returns and liquidity are mostly for the developed markets. The disperse ownership in the corporation and more well informed investors in the developed markets support their findings. On the other hand, the nature and behaviour of emerging stock markets such as Malaysia di

ISO/IEC 27001 is an international standard that provides a set of requirements for an Information Security Management System (ISMS) implementation. A risk assessment exercise for an ISMS implementation requires human expertise with comprehensive understanding and considerable knowledge in information security. A common risk assessment exercise is b

Malaysia is one of the largest bird’s nest exporters particularly to China and Hong Kong market. However, Malaysia multimillion ringgits bird’s nest industry has been hit hard by China’s ban and a series of scandals, with a drop in sales and prices. In light of the emerging food safety issues that surrounds the Malaysian Edible Bird’s Nest
