In this study, a multi objective optimization for end milling of Al 6061 alloy has been presented to provide better surface quality and higher Material Removal Rate (MRR). The input parameters considered for the analysis are spindle speed, depth of cut and feed. The experiments were planned as per Taguchis design of experiment, with L27 orthogonal array. The Grey Relational Analysis (GRA) has b...

The drum agglomeration of nickel laterite and gold ores has been optimized through the design of experiments (DOE) using a Taguchi L16 (45) orthogonal array to determine the optimum conditions for maximizing average agglomerate size and minimizing the amount of fines. The effects of controllable operating factors including moisture content (nickel laterite ore: 34-37%; gold ore: 7-10%), retenti...

This paper involves the multi-objective optimization of process parameters of AlSi10Mg/9 wt% alumina/3 wt% graphite in Electrical Discharge Machining for obtaining minimum surface roughness, minimum tool wear rate and maximum material removal rate. The important machining parameters were selected as peak current, flushing pressure and pulse-on time. Experiments were conducted by selecting diffe...

Chitinase production by newly isolated Serratia marcescens B4A was optimized following Taguchi’s array methods. Twenty-three bacterial isolates were screened from shrimp culture ponds in the South of Iran. A chitinase-producing bacterium was isolated based on it’s ability to utilize chitin as the sole carbon source. The isolate designated as B4A, was identified as Serratia marcescens based on i...

The present work analyses different parameters of end milling to minimize the surface roughness for AISI D2 steel. D2 Steel is generally used for stamping or forming dies, punches, forming rolls, knives, slitters, shear blades, tools, scrap choppers, tyre shredders etc. Surface roughness is one of the main indices that determines the quality of machined products and is influenced by various cut...

Order picking is the process of retrieving products from storage in response to a specific customer order. Although this process’ design has significant impact on warehouse global performance, a practical-oriented design procedure is still lacking in literature. This paper presents a novel order picking system design methodology based on Design for Six Sigma approach, that aims to assist design...

In this paper, factorial design experiments and Taguchi methods have been used to monitor the quality of the incoming raw material, product quality during processing, and the final product quality of a process industry. The data collected and results obtained are presented and discussed. The analysis made on the experimental results provided information to improve the quality of the process ind...

Research on practical design verification techniques has long been impeded by the lack of published and yet detailed error data. Over the last few years we have systematically collected design error data from a number of academic microprocessor design projects. We present an analysis of this data and report on the lessons learned in the collection effort.

The popularity of composite materials usage is increasing due to its superior strength characters racing the traditional materials in strength to weight ratio. The developments of new materials are on the anvil and are growing day by day. In this work, two-body abrasive wear test with different loads and abrading distances were performed at room temperature by using a pin on a disk apparatus to...
