The aim of this research work is to evaluate the effects of coolant including nano- powder material for the cooling purpose in milling process and comparing the results with the conventional coolant. Generation heat and weak heat transfer reduces the tool life and also deteriorate surface roughness during milling operation. To overcome this problem, it is necessary to use coolant for cooling as...

This paper presents, the experimental study has been made to optimize the process parameters during machining of H-13 by wire electrical discharge machining (WEDM) using Taguchi L9 orthogonal array method. Following input process parameters of WEDM [Pulse-On time (TON), Pulse-Off time (TOFF) and Wire Speed rate (WS) and Wire Tension (WT)] were chosen as variables to study the process output in ...

Many manufactured products require machining at some stage of their production sequence. Generally, machining ranges from relatively rough cleaning of castings to high-precision micromachining of mechanical components that require narrow tolerances. It is estimated that of all machining processes about 40% pertain to turning. Turning is the most common way for processing rotational (symmetrical...

INTRODUCTION The continuing drive towards miniaturisation in a number of industries including semiconductor, optoelectronic and medical is stimulated by requirements which include enhanced functionality, performance and reliability, increased energy efficiency, a cleaner environment, improved healthcare, together with reduced costs etc. [1, 2]. Also, new products for fastgrowing industries like...

The development of modern mechanical engineering forces us to constantly improve the technology processing materials and look for ways not only quality products but also increase efficiency process itself. This article discusses an alternative method finish product, which can replace traditional grinding, magnetic abrasive treatment. is a solution that allows you obtain high surface processed p...
