High Speed End Milling of Silicon Using Diamond Coated Tools with Air Blowing
Research Output | Dar Al-hikmah Library | IIUM Only

A new method of ductile mode machining of silicon using high speed end milling with diamond coated tool and assisted by compresses air blowing has been developed. This method is capable of removing the ductile and gummy chips before they get deposited on the machined surface since gummy chips can not be removed by mechanical means once they are dep

Tool Wear and Surface Roughness Aspects in Heat Assisted End Milling of Aisi D2 Hardened Steel
Research Output | Dar Al-hikmah Library | IIUM Only

With the advent of several advanced difficult-to-cut materials, and with the availability of heat resistant tool materials has posed a great challenge in industries. Hardened steel is one of these difficult-to-cut materials. During the last few decades numerous studies have been conducted to improve the machinability of these materials and many lar

Wear Mechanism in End Milling of Inconel 718
Research Output | Dar Al-hikmah Library | IIUM Only

Nickel-based, creep-resistant, superalloy Inconel 718 is amongst the most difficult alloys to machine. The main reason for the poor machinability of the alloy is the high work-hardening rate by the precipitation of a γ’ phase and the presence of hard abrasive phases such as titanium carbide, niobium carbide and the Ni3AlTi phase. Generally, incr

A New Method for Chatter Suppression and Improvement of Surface Roughness in End Milling of Mild Steel
Research Output | Dar Al-hikmah Library | IIUM Only

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 [

Perceived Stress Level and its Stressors Among Malaysian Undergraduate Nursing Students During Covid-19 Pandemic
Research Output | Dar Al-hikmah Library | IIUM Only

Introduction: As COVID-19 Pandemic hit across the globe, the closure of higher institutions and the shifting to online platform has become the stress factors related to learning activities for the nursing students. Hence, this study was conducted among Malaysian undergraduate nursing students to determine the level of perceived stress and to examin

Observation on Antioxidant Activity from Leaves, Callus and Suspension Culture of Justicia Gendarusa
Research Output | Dar Al-hikmah Library | IIUM Only

This Antioxidant activity and phenolic compound was found in Justicia gendarussa (JG) via total phenolic content (TPC) and α,α-diphenyl-β-pycrilhydrazil hydrate (DPPH) radical scavenging assays. The assays were applied on aqueous and methanolic extracts of leaves, callus culture and cell suspension culture of JG. Callus was induced from green an

Research Output | Dar Al-hikmah Library | IIUM Only

Cancer is a disease which known throughout the world. There are many available commercial and alternative treatments to treat cancer. Mango (Mangi(era indica L) is one the popular tropical fruits found in Malaysia. Mango is a wide variety that can easily be found in this country. It is known for its vibrant flesh colour, juicy texture, sweet flavou

Relative Performances of Preheating, Cryogenic Cooling and Hybrid Turning of Stainless Steel Aisi 304
Research Output | Dar Al-hikmah Library | IIUM Only

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
