This paper investigates the effects of three parameters (reaction temperature, feedstock particle size and nitrogen flow rate) towards solid (char) yield from pyrolysis bamboo. Three-factor, three-level Taguchi’s L9 Orthogonal Array was used as experimental design. The char at reaction temperatures 300-500°C, 100-1000 μm, rate 100-300 ml min −1 were investigated. maximum predicted based on sign...

This study discusses the application of Taguchi method in assessing minimum entropy generation and maximum heat transfer rate for natural convection in an enclosure embedded with isothermal cylinder. The simulations were planned based on Taguchi’s L25 orthogonal array with each trial performed under different conditions of position and aspect ratio (AR) of the cylinder. The thermal lattice Bolt...

High-speed steel (HSS) tools are the most commonly used tools in small and medium-scale industry. Cryogenic treatment can be used to enhance the tool life. Studies on cryogenically treated (CT) cutting tools show micro structural changes in the material that can influence the life of the tools significantly. This paper primarily reports performance of CT HSS tools as compared to untreated (UT) ...

Due to significant environmental advantages, biocomposites have recently received increasing attention. In the present research, strength of hat-shaped coir fiber biocomposites tubes reinforced with nano powder was evaluated experimentally under 3-point bending tests. The tubes were manufactured using hand lay-up technique and based on Taguchi design of experiment. The effects of different para...

Electrical discharge machining (EDM) is a wellestablished non-conventional machining process, used for manufacturing geometrically complex or hard and electrically conductive material parts that are extremely difficult to cut by other conventional machining processes. But sometimes poor surface finish and low volumetric material removal rate limits its use in the industry. To diffuse this probl...

Abstract—This paper presents a design and optimization for a compliant gripper. The gripper is constructed based on the concept of compliant mechanism with flexure hinge. A passive force regulation mechanism is presented to control the grasping force a micro-sized object instead of using a sensor force. The force regulation mechanism is designed using the planar springs. The gripper is expected...

The influence of medium ingredients on extracellular dextransucrase production by a new bacterial strain Weissella confusa Cab3 (Genbank Accession Number JX649223) was evaluated using fractional factorial design of Taguchi’s orthogonal array. Four metabolism influencing factors viz. sucrose, yeast extract, K2HPO4 and Tween80 were selected to optimize dextransucrase production by W. confusa Cab3...

This investigation proposes a grey-based Taguchi method to solve the multi-response problems. The grey-based Taguchi method is based on the Taguchi’s design of experimental method, and adopts grey relational analysis (GRA) to transfer multiresponse problems into single-response problems. In this investigation, an attempt has been made to optimize the drilling process parameters considering weig...

Suppose several two-valued input-output systems are designed by setting the levels of several controllable factors. For this situation, Taguchi method has proposed to assign the controllable factors to the orthogonal array and use ANOVA model for the standardized SN ratio, which is a natural measure for evaluating the performance of each input-output system. Though this procedure is simple and ...

In this study, the Taguchi method is used to find the optimal process parameters for an injection moulding machine that was used to produce a consumer product (plastic tray) from polypropylene (PP) plastic material. An orthogonal array (OA), main effect, signal-to-noise (S/N) ratio, and analysis of variance (ANOVA) were employed to investigate the bending characteristics of the tray under a con...
