In a developed economy, market for any product is generally highly competitive. To be successful in such a condition producer has to provide output which has distinctive advantages over others e.g. innovative designs and ideas, extremely good quality related to aesthetics and functional aspects, etc. Quality is a good tool for competition. It is necessary for customer's satisfaction and also fo...

Modernization of mechanical industry has lead to the increase in demand for hard and tough materials and thus various non traditional methods have been developed in order to machine such hard and tough materials. Wire Electric discharge machine is one of the most commonly used machine which is employed in machining of conductive metals of any hardness or that are difficult or impossible to cut ...

The aim of this research work is focused on optimization of process parameters under Minimum Quantity Lubrication (MQL) using nano fluid in turning of AISI 4340. A study of effect of process parameters in turning of AISI 4340 under MQL condition with nano fluid (Multiwalled Carbon Nano Tube) on the cutting force generated and machined surface roughness is carried out. In the experiment conducte...

Extremely hard materials can be easily machined by Electrical Discharge Machining process due to its thermal erosion nature. In this process, the amount of material removed is directly proportional to the discharge current. Due to the stochastic nature of the thermal erosion process, the discharge current is varied for every applied electrical pulse. It results in different levels of material r...

In this study, effect of square cutout and beam widths on eigenvalue buckling analysis beams is evaluated using finite element Taguchi methods. ANSYS software used to perform the analyses were conducted L9 orthogonal array with three control factors. Each factor has levels. The first considered as position whereas second was assumed widths. influence levels cutouts responses determined signal-t...

Basalt rock has great potential in Lampung Province but is only used as a building construction material. superior characteristics such abrasion/wear resistance, compressive strength and chemical reaction resistance making it suitable filler or reinforcement for composites. This study aims to determine the effect of basalt powder sintering reinforcing on mechanical physical properties polymer m...

With the increasing demands of high surface irregularities and machining of composites, conventional machining processes are now being replaced by high speed Computer Numerical Control (CNC) machines. In this paper aluminium silicate made from alloying aluminium and silicon oxide made from rice husk are used. The machining of the alloy on CNC machine is carried out. In addition to speed, feed a...

This study investigated the optimization of End milling of AISI 1018mild steel by various lubricants using the Grey relational analysis method. Quaker 7101, Blasocut strong 4000 and Velvex have been selected as lubricant. All the experiment are carried out at different cutting parameter (Number of Tool Flutes, Depth of cut, Spindle speed and Feed rate) in various lubricant assisted environment....

The present paper envisages the multi-response optimization of certain process parameters like total sugars concentration, C/N ratio and incubation time on rhamnolipid yield, surface tension reduction, biomass formation and substrate utilization, in rhamnolipid production by a Pseudomonas aeruginosa mutant strain grown on clarified blackstrap molasses, under L9 orthogonal array in Taguchi desig...

This study investigates optimal parameter setting in abrasive waterjet machining (AWJM) on aluminium alloy AA 6351, using taguchi based Grey Relational Analysis (GRA) is been reported. The water pressure, traverse speed and stand-off-distance were chosen as the process parameters in this study. An L 9 orthogonal matrix array is used for the experimental plan. The performance characteristics whi...
