Investigation of the Machinability of Inconel 718 in Room Temperature and Preheated Conditions
Research Output | Dar Al-hikmah Library | IIUM Only

Inconel 718 is widely used in the aviation, space, navigation and shipping industries because of its outstanding properties. The very mechanical characteristics that give this alloy the highly valued properties also make it one of the most difficult-to-machine aerospace materials. Due to the hardness of nickel-based super-alloys, such as Inconel 71

The Method of Chatter Suppression in End Milling Operation
Research Output | Dar Al-hikmah Library | IIUM Only

Various methods of chatter suppression have been introduced to control chatter during machining processes. In this research an innovative approach of chatter suppression during end milling operation using ferrite magnet is being proposed. Design of experiment has been conducted using the Response Surface Method (RSM). The effect of application of m

Development of Tool Life Prediction Model of Tialn Coated Tools During the High Speed Hard Milling of Aisi H13 Steel
Research Output | Dar Al-hikmah Library | IIUM Only

Considering the demand for reduced cycle time and increased productivity hard turning and milling have become a useful alternative when high material removal rate is an immense requirement. Advantages in hard machining incorporate the complete machining process with a single fixture setup, eliminating intermediate heat treatment and final grinding

Application of Permanent Electromagnet for Chatter Control in End Milling of Medium Carbon Steel
Research Output | Dar Al-hikmah Library | IIUM Only

In machining process, the machine, cutting and the work piece are integrated to form structural systems which create a dynamic characteristic. Soliman, Ismail [1] observed that vibration can be divided into three types, free vibrations, force vibrations and self-excited vibrations (chatter). As in this project, the focus is more on the chatter that

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

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

Influence of the Elastic System and Cutting Parameters on Chatter During End Milling of Aluminium and Aluminium Alloy on Vmc
Research Output | Dar Al-hikmah Library | IIUM Only

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]

Optimization of Surface Roughness in High Speed End Milling of Titanium Alloy Ti-6al-4v Under Dry Conditions
Research Output | Dar Al-hikmah Library | IIUM Only

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

Palliative Care and Hospice Care from the Perspective of the Maqasid Sharī'ah
Research Output | Dar Al-hikmah Library | IIUM Only

It is crucial that Muslim healthcare professionals understand the Islamic perspective of life, health, illness, and death issues to provide a holistic care to their patients, especially those who are terminally or critically ill. Terminally ill patients would inevitably require specialized treatment such as palliative care or hospice care, dependin

Some Aspects of Improved Machinability in Preheated Machining of Titanium Alloy Ti-6al-4v
Research Output | Dar Al-hikmah Library | IIUM Only

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

Modeling for Surface Roughness in end-Milling of Titanium Alloy Ti-6al-4v Using Uncoated wc-Co Inserts
Research Output | Dar Al-hikmah Library | IIUM Only

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
