Most published research works on the development of tool life model in machining of hardened steels have been mainly concerned with the turning process, whilst the milling process has received little attention due to the complexity of the process. Thus, the aim of present study is to develope a tool life model in end milling of hardened steel AISI

The objective of a robust fault reconstruction scheme is to generate an accurate reconstruction of the fault that is unaffected by disturbances. A typical method for robust fault reconstruction is to reconstruct the faults and disturbances, which is conservative and requires stringent conditions. This paper investigates and presents conditions that

Majority of the published research works on modeling of tool life in machining of hardened steels are based mainly on the turning process, whilst the hard milling process has rarely been adopted. This work is aimed to determine the optimum cutting condltlons leading to maximum tool life in end miling of AISI 02 hardened steel using PVD TIAIN coated

The tool life of TiAlN coated carbide tools was investigated at various combinations of cutting speed, feed and preheating temperature in end milling of AISI 02 hardened steel under room temperature and preheated machining conditions. Sufficient number of experiments was conducted based on the central composite design (CCD) which was adopted by res

In this paper, we presents a secure(noise-resistant algorithm for data communication over the noisy channel , the message is converted to non-linear Hadamard code, which is having the maximum hamming distance, which makes it more fault-tolerant in comparison to the ASCII input. The translated message is encrypted with a random signal by specific mi

Pneumothorax is the presence of air in the pleural cavity. It can be classified into spontaneous, traumatic or iatrogenic. The majority of pneumothorax cases are spontaneous, which can be further classified into primary spontaneous pneumothorax (PSP) or secondary spontaneous pneumothorax (SSP), defined by the absence or presence of obvious underlyi

Objective: The aim of this was to compare energy and macro-nutrients intakes in university hostel students in two Ccuntries of Asia Methods: Female students from the hostels of International Islamic University, Malaysia, Kuantan Campus and NWFP, Agricultural University Peshawar- Pakistan were assessed for the energy and macro-nutrients intakes. A t

A study was performed to investigate the performance of coated carbide inserts in end milling of AISI 02 hardened steel (60-62 HRC), under room temperature and workpiece preheated conditions. The effects of cutting conditions on tool wear morphology and machined surface finish were also investigated. Tests on end milling were conducted on a vertica

All aspects of life are subject to constant transformation, and the present rulings, which are interpreted by jurists, are no exception. Islam is a way of life and consequently the Islamic Law has to be interpreted in such a way that accommodates changing circumstances and solves new problems. Thus, the principle of ijtihâd represents a worldwide

We analyze the cyclical behavior between outputs and prices in major ASEAN economies, namely Malaysia, Indonesia, Thailand, Singapore and the Philippines over two sample periods: the pre-crisis period (1990 to 1996) and the post-crisis period (2000 to 2006). Specifically, the study aims to shed the light on two issues:(i) the possibility that there
