Decreasing vibration amplitude during end milling process reduces tool wear and improves surface finish. Mathematical model has been developed to predict the acceleration amplitude of vibration in terms of machining parameters such as helix angle of cutting tool, spindle speed, feed rate, and axial and radial depth of cut. Central composite rotatable second-order response surface methodology was employed to create a mathematical model, and the adequacy of the model was verified using analysis of variance. The experiments were conducted on aluminum Al 6063 by high-speed steel end mill cutter, and acceleration amplitude was measured using FFT analyzer. The direct and interaction effect of the machining parameter with vibration amplitude were analyzed, which helped to select process parameter in order to reduce vibration, which ensures quality of milling. © 2010 Springer-Verlag London Limited.

In the advent of modernization, pollution problems have also emerged in various forms. Effluent treatment involving biodegradable organic wastes can be treated biologically in most cases. Activated sludge process is used in the studies. The organic waste is introduced into a reactor where bacterial culture is kept in suspension. Sludge volume index is used to ascertain the settling characteristics. Settling studies were performed on dairy waste for different initial mean cell residence time and Mixed Liquor Suspended Solids (MLSS) concentrations. To prepare the sludge for various θc (7, 9, 11, 13 and 15) a batch reactor of 20 liters capacity was used (A bench scale settling tests). Further all these equations were combined to form a model connecting three parameters viz. Mixed liquor suspended solids concentration, Sludge Volume Index (SVI) and Mean Cell Residence time (MCRT). This model could be used to help the operator of ASP to compute the return sludge and also the sludge volume index values can help to maintain the desired underflow concentrations. © 2011 CAFET-INNOVA TECHNICAL SOCIETY.

The prediction of delta ferrite content expressed in terms of ferrite number in austenitic stainless steel welds is very helpful in assessing its performance. The final ferrite content determines the properties of weldments such as strength, toughness, corrosion resistance, and phase stability. This paper presents a study on the effect of process parameters on ferrite number in 202 grade stainless steel gas tungsten arc welded plates (GTAW). Experiments were conducted based on response surface methodology. The ferrite number was determined by using a ferrite scope and by using DeLong diagram. A mathematical model was developed correlating the important controllable GTAW process parameters like welding gun angle, welding speed, plate length, welding current, and shielding gas flow rate with ferrite number. The adequacy of the model was checked using analysis of variance technique. The developed model is very useful to quantitatively determine the ferrite number. The main and interaction effects of the process parameters are presented in graphical form that helps in selecting quickly the process parameters to achieve the desired results. © 2012 Springer-Verlag London Limited.

Cutting forces should be kept in minimum to reduce tool deflection, vibration and tool wear. Mathematical model has been developed to predict the cutting forces in terms of process parameters such as helix angle of cutting tool, spindle speed, feed rate, axial and radial depth of cut. Response surface methodology was employed to create a mathematical model and the adequacy of the model was verified using analysis of variance. The experiments were conducted on aluminium Al 6063 by high speed steel end mill cutter and the cutting forces were measured using milling tool dynamometer. The direct and interaction effect of the process parameter with cutting forces were analysed, which helped to select process parameter in order to keep cutting forces minimum, which ensures the stability of end milling process. © 2012 Inderscience Enterprises Ltd.

Bhavani is one of the important Rivers in the Tamilnadu. Many industries, particularly textile processing units, tanneries, and distillery units, are situated on the banks of Bhavani River. These industries let out untreated and partially treated effluents in to the river stream. It is, therefore, decided to study the quality of water and to estimate its pollution load in the River Bhavani near Mettupalayam region. Samples of water were collected at selected points and physio-chemical examinations were carried out. It was observed that at the start at the place before the mixing of effluent the water quality in river was good, but showed a progressive decline from its origin to further distances as it passes through human settlements and industrial areas.
