This paper discusses the experimental investigation to find out the optimal electrolyte composition in improving the surface quality of the gear teeth profile during surfacing finishing of bevel gears by the electrochemical honing process. In this study, AISI 1040 was used as the workpiece material, mixtures of sodium chloride and sodium nitrate in(More)
This paper presents the micro-finishing of bevel gears by electrochemical-mechanical finishing (ECMF) process under different experimental conditions of current, rotating speed of workpiece and electrolyte concentration. These different experimental conditions are planned on the basis of box behnken design (BBD) design of experiments (DOE) technique of(More)
— A hyper-redundant manipulator has the advantage that it can be used in constraint space; however the control of hyper-redundant manipulator is difficult. This paper presents a concept of virtual link based two degrees of freedom (DOF) controller. With the proposed controller, manipulator of any number of links can be reduced to either a 2-link virtual(More)
Endoscopes have been in use for many procedures including limited surgery. A very common application of endoscopes been used in surgery is biopsy. However present Endoscopes has certain limitations such as restricted degrees of motion of tool leading to poor manipulation of tissues, limited visualization of surgical field, increased sensitivity to hand(More)
This paper proposes an improved reversible color to textured gray image mapping. The method was originally devised using the wavelet transform, where high-frequency subbands are replaced by subsampled chrominance plane. The problem with this method was lower Peak Signal to Noise Ratio (PSNR). Proposed method is an attempt to improve the original method by(More)
