Coated abrasives are extensively used for manual operations such us cleaning, deburring, polishing, etc. With the trend towards increased production rates, demands on coated abrasive belts are becoming increasingly severe. . Experimental investigations are to be made to know the effects of the process parameters on the performance of the surface belt grinding process. It is necessary to investigate the effect of flexing along with other input process parameters on output. In the present work the Taguchi’s experimental design method is used for performing the belt grinding process on the stainless steel AISI 304 and optimizing the process parameters. Thus, this research aims at right choice of flexing and grinding parameters for the coated abrasive belts. The results were further analysed by Taguchi’s signal to noise ratio for finding the optimum process parameters.

Present investigation deals with the effect of varying process parameters on the characterization of plasma sprayed fly ash - Al2O3 composite coatings using Taguchi’s experimental design method to conduct experiments and optimization of process parameters. Parameters such as standoff distance, powder feed rate and current density were considered for the optimization of bond strength, porosity and hardness. The significance of the parameters and their optimum level is determined by using ANOVA. Experiments were carried out to validate the effect of optimum process parameters on response characteristics and found that selected optimal combination of process parameters is able to achieve the best results.

Laser Cladding is one of the leading processes within Additive Manufacturing technologies, which has concentrated a considerable amount of effort on its development. In regard to the latter, the current study aims to summarize the influence of the most relevant process parameters in the laser cladding processing of single and compound volumes (solid forms) made from AISI 316L stainless steel powders and using a coaxial nozzle for their deposition. Process speed, applied laser power and powder flow are considered to be the main variables affecting the laser cladding in single clads, whereas overlap percentage and overlapping strategy also become relevant when dealing with multiple clads. By setting appropriate values for each process parameter, the main goal of this paper is to develop a processing window in which a good metallurgical bond between the delivered powder and the substrate is obtained, trying simultaneously to maintain processing times at their lowest value possible. Conventional metallography techniques were performed on the cross sections of the laser tracks to measure the effective dimensions of clads, height and width, as well as the resulting dilution value. Besides the influence of the overlap between contiguous clads and layers, physical defects such as porosity and cracks were also evaluated. Optimum process parameters to maximize productivity were defined as 13 mm/s, 2500 W, 30% of overlap and a 25 g/min powder feed rate.

This paper presents an experimental study on the diametrical overcut and taper obtained during the machining of micro holes by electro-discharge machining (EDM). Many trials were taken by machining a 2.0 mm electrolytic copper rod to 0.50 mm under various conditions to analyse the effect of process parameters by wire electric discharge grinding process (WEDG). The optimum process parameters were determined by Taguchi’s method. Then a set of electrodes were produced with the determined optimum process parameters and were used to machine micro holes on Ti-6Al-4V alloy. The diameters of the holes were measured and the effects of various parameters were analysed for the variation in taper and diametrical overcut. The experimental results were analysed using analysis of variance approach.

In this paper, we investigates the different dose and tilt HALO implant step in order to characterize the 45nm NMOS device. Besides HALO, the other two process parameters are oxide growth temperature and source/drain (S/D) implant dose. The settings of process parameters were determined by using Taguchi experimental design method. This work was done using TCAD simulator, consisting of a process simulator, ATHENA and device simulator, ATLAS. These two simulators were combined with Taguchi method to aid in design and optimizer the process parameters. Threshold voltage (VTH) results were used as the evaluation variable. The results were then subjected to the Taguchi method to determine the optimal process parameters and to produce predicted values. In this research, oxide growth temperature was the major factor affecting the threshold voltage (69%), whereas halo implant tilt was the second ranking factor (20%). The percent effect on Signal-to-Noice (S/N) ratio of halo implant dose and S/D implant dose are 6% and 5% respectively. As conclusions, oxide growth temperature and halo implant tilt were identified as the process parameters that have strongest effect on the response characteristics. While S/D implant dose was identified as an adjustment factor to get threshold voltage for NMOS device closer to the nominal value (0.150V) at tox= 1.1nm.

In the present research work, Stainless Steel AISI 316 as per ASTM A 276 has been employed as the base material to perform Spark and Wire-Cut EDM. The main agenda behind performing Spark and Wire-Cut EDM on Stainless Steel AISI 316 is to find out the effect of machining parameters like surface roughness (SR) and MRR (Material Removal Rate). In-case of wire-cut EDM, brass wire) of 0.25 mm diameter is used as a tool and distilled water is used as dielectric fluid and experimental process parameters like Current (A) (2, 3 and 4 Amps), Pulse ON time (B) (25, 30 and 35 μs) and Wire feed rate (C) (40, 60 and 80 mm/sec). Similarly for spark cut EDM copper rod of 12 mm diameter and 65 mm length. Process parameters like Current (A) (6, 12 and 16 Amps), Voltage (B) (30, 35 and 40 Volts) and Pulse ON time (C) (50, 100 and 200μs) were maintained during the experimentation. Statistical tools ANOVA & L-9 Orthogonal Array (OA) have been employed to optimize the machining parameters like Surface Roughness (SR) and MRR (Material Removal Rate).

There is an increasingly recognised requirement for high dimensional accuracy in micro-bent parts. Springback has an important influence on dimensional accuracy and it is significantly influenced by various process parameters. In order to optimise process parameters and improve dimensional accuracy, an approach to quantify the influence of these parameters is proposed in this study. Experiments were conducted on a micro W-bending process by using an I-optimal design method, breaking through the limitations of the traditional methods of design of experiment (DOE). The mathematical model was established by response surface methodology (RSM). Statistical analysis indicated that the developed model was adequate to describe the relationship between process parameters and springback. It was also revealed that the foil thickness was the most significant parameter affecting the springback. Moreover, the foil thickness and grain size not only affected the dimensional accuracy, but also had noteworthy influence on the springback behaviour in the micro W-bending process. By applying the proposed model, the optimum process parameters to minimize springback and improve the dimensional accuracy were obtained. It is evident from this study that the I-optimal design-based RSM is a promising method for parameter optimisation and dimensional accuracy improvement in the micro-bending process.
