In finish-machining, geometric accuracy and surface quality m adversely affected by the tool wear at the minor flank and nose area. This paper describes an investigation into "comprehensive" tool wear estimation, including flank-, crater-. minor flank-, and nose-wear, based on an analysis of dynamic cutting force in oblique machining. The force, measured in terms of its three orthogonal compone...

Background: This study was designed to investigate the efficacy of Pentoxifylline (PTX) in the treatment of irradiated wounds. Materials and Methods: Ten female pigs of the Large White strain were used in these investigations. Six skin fields, 4 * 4 cm and separated from each other by 4 cm, were marked out on each flank and those on left flank were irradiated with 18Gy single dose of 250 kV X-r...

We present a case of a patient with xanthogranulomatous pyelonephritis (XGP) presenting with a large (18 × 12 cm) left-sided flank mass with worsening left flank pain. CT abdomen/pelvis demonstrated a left kidney with parenchyma replaced by multiple large hypodense collections containing fluid and gas, a left staghorn calculus, and a communication between the kidney and large flank collection. ...

in manufacturing industry, it has been acknowledged that tool wear prediction has an important role in higher quality of products and acceptable efficiency. being an emerging area of research in recent years, drilling tool wear is an important factor which directly affects quality parameters of machined hole such as hole centring, roundness, burr formation and finished surface. in this paper, t...

Due to their constant and relatively rapid growth, volcanic edifices are inherently unstable. Flank instability is observed at many polygenetic stratovolcanoes, composite volcanoes and shield volcanoes worldwide. Flank instability may occur suddenly, or develop in a more continuous and subtle way, accelerated by triggering events (magma emplacement, eruptions and earthquakes). Destabilization i...

a high strength nickel chromium alloy (50cr-50ni-nb alloy), commonly referred to as in-657, is specifically used for components in furnaces which are fired by low grade fuel oils containing high levels of vanadium, sodium and sulphur. the purpose of this study is to experimentally investigatethe effect of machining parameters on machinability in turning of inconel 657. the considered parameters...

This paper presents and compares methods of error metrics used to measure the error for the flank milling of a machined ruled surface. The aim of this work is to propose a new scheme for error approximation that is easy to implement and gives better error assessment when using optimization techniques to determine tool position. We propose using as the error calculation an approximation to the d...
