the present study concentrates on the synthesis of au nanoparticles (aunps) using aqueous solution of polyvinylpyrrolidone (pvp) and tetrachloroaurate by different methods as thermal, sonochemical and electrochemical reduction. the pvp has been used as a reducing agent and acts as a stabilizer for au nano particles that obtained as principal product. in all synthesis procedures, the active radi...

This paper presents an application of the Taguchi method parameter design to optimize the surface roughness, tool wear and cutting force by hard turning process. The Taguchi parameter design method is an efficient method in which response variable can be optimized, given various controls and using fewer experimental runs. Hard turning is the latest trend in all manufacturing industries and it i...

Purpose – To solve the trade-offs between marketing and R&D domains and to minimize information loss in new product development (NPD), this study proposes an integrated design process as a new solution to the interface system between the two domains. Design/methodology/approach – House of Quality integrated with multivariate statistical analysis is used for determining important design features...

In this paper we propose the use of design capability indices for use in robust design. These indices allow the design requirements to vary within a certain range. Design capability indices are based on process capability indices from statistical process control and provide an alternate approach to the use of Taguchi’s signal-to-noise ratio which is often used for robust design. Successful impl...

In the measurement process, there are many parameters affecting the measurement results: the influence of the probe system [3,5,7,15,10,16,17,19,21], material stiffness of measured workpiece [7], the calibration of the probe with a reference sphere [3], the thermal effects [14]. We want to obtain the limits of a measurement methodology to be able to validate a result. The study is applied to a ...

Taguchi method was known as an off-line quality control methodology to be used in many industries. Until now, most applications only focus on optimizing a single-response in a static system. Furthermore, due to the increasing complexity of the product design, more than one quality characteristic must be considered simultaneously to improve the production quality. Therefore, there are several st...

Robust design uses the parameter design approach of Genichi Taguchi to optimize designs of products and processes with the objective of building in insensitivity to noise. Noise is any kind of uncontrolled variation in the environment of operation of the product or process that could affect performance. If we recognize how variation in the environment (e.g., energy source, raw materials, heat a...
