The purpose of this search is to study the main factors on surface roughness in (AL-2024) using a CNC milling machine for an HSS tool with flat end milling. And by Taguchi experience design method conserve time and costs. To determine optimal values ​​of optimization. We then performed analysis variance regression. Confirmation tests were verify work. cutting process consists two stages; first ...

During the bull-nose end milling operations of thin-walled structures, chatter usually occurs and adversely affects cutter performance, finished surface quality, production efficiency. To accurately predict stability, a suitable dynamic model with effective system parameters is required. In this article, three-degree-of-freedom (3-DOF) developed to analyze stability cylinders, in which dynamics...

In this paper, optimum positioning of the conical cutter for five-axis flank milling of slender surfaces is addressed from the perspective of approximating the tool envelope surface to the data points on the design surface following the minimum zone criterion recommended by ANSI and ISO standards for tolerance evaluation. Based on the observation that a conical surface can be treated as a canal...

We consider the prediction algorithm and performance evaluation for prognostics and health management (PHM) problems, especially the prediction of remaining useful life (RUL) for the milling machine cutter and lithium‐ion battery. We modeled battery as a voltage source and internal resisters. By analyzing voltage change trend during discharge, we made the prediction of battery remain discharge ...

A new extraclion system has been designed and constructed which allows the extraction of gases from air bubbles in ice without melting it. The ice sample of abollt 500 g is crushed in an evacuated container by a milling cutter, and the gas escaping from the opened bubbles is collected by condensation at 15 K. Results of CO 2 analyses of extracted gases a re discussed with respcCI to possible co...
