The use of a minimum quantity of lubrication (MQL) with extremely low consumption of lubricant in machining processes has been reported as a technologically and environmentally feasible alternative to conventional flood cooling. In hot machining, the external heat source is applied during machining that will assist to increase machining performance. Many external heating techniques are availabl...

In recent years, advanced materials with unique metallurgical properties such as super alloys, composites and ceramics have been developed to meet the demands of extreme applications. While these materials are harder, tougher, less heat sensitive and more resistant to corrosion and fatigue, they are also difficult to machine. Advanced materials are being widely used these days not only in the a...

Abstract. There are considerably rigorous requirements for accuracy and stability of the mechanism to accomplish large-scale complex surface machining tasks in aerospace field. In order improve stiffness performance parallel mechanism, this paper proposes a novel three degrees freedom (DOF) redundantly actuated 2RPU-2SPR (where R, P, U S stand revolute, prismatic, universal spherical joints, re...

In order to improve efficiency of cutting process in production industry, development of new steel which has good machinablity is desired. The work material which has good surface roughness, easy breakable chip and small tool wear as the good machinablity is expected. And the free-machining steel was developed owning to adding elements which could make the machinablity better. Of all others, le...

Article history: Received: 27.6.2013. Received in revised form: 14.11.2013. Accepted: 19.11.2013. Aluminum based Metal Matrix Composites (AlMMC) have been found in different industrial applications due to their excellent properties compared to conventional materials. Machining of these composites is difficult due to their hard particle reinforcements. The wider usage of these composites is limi...

Correct selection of manufacturing condition is one of the most important aspects which should be considered in the majority of manufacturing processes,  particularly in the process related to advanced machining process like electrical discharge machining. In electrical discharge machining (EDM), dielectric fluid plays an important role since machining characteristics are greatly influenced by ...

This project aims at developing high-throughput platforms for bioprocess developments. Based on the membraneaerated microbioreactor [1], we have realized a microlitervolume, actively-mixed, and polymer-based microbioreactor by microfabrication and precision machining of PDMS and PMMA for batch [2] and continuous cultures [3] of microbial cells. Biological applications of microbioreactors, such ...

Ultrasonic machining (USM) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. This paper addresses the concept and development of an expert system (ES) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...
