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 [

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

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

Influence of Chatter on Tool Life During End Milling of Aluminium and Aluminium Alloy on Vertical Machining Centre (Vmc)
Research Output | Dar Al-hikmah Library | IIUM Only

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

Parameter al-Dharīah Menurut Perspektif Syariah (Parameter of al-Dharīah from the Perspective of Shari’ah)
Research Output | Dar Al-hikmah Library | IIUM Only

Al-Dharīʿah is an important concept in the issuance / establishment of Islamic law. In general, it covers two main parts, namely sadd al-dharīʿah and fath al-dharīʿah. However, this second part (fath al-dharīʿah) is less discussed in depth and extensively by previous scholars. Thus, this study is to produce pragmatic and practical parameter
