Abstract
Surface roughness is reduced by optimising the machining parameters. This research analyses the effect of machining parameters on surface quality of aluminium 2024 T351 in milling of semi-circular pocket with carbide tool on 5-axis hybrid parallel kinematic machine (HPKM). Three different segmented surfaces were selected on semi-circular pocket and investigated the influence of machining parameters. The selected parameters are spindle speed, feed rate and depth of cut. Investigation of this study results in the optimum parameters that could produce good surface finish. The effect of these cutting parameters is evaluated using L9 Taguchi orthogonal array, s/n ratio, analysis of variance (ANOVA). Based on the result analysis, good surface finish can be obtained at high cutting speed, low feed rate, and low depth of cut. Also, the maximum influence of feed rate among the selected surface segments was ascertained.
期刊介绍：
The objective of IJASM is to establish an effective channel of communication between academia, industry and persons concerned with the design and development of systems. Change is eternal and perpetual, irrespective of type of system. Systems created in the course of the advance of human civilization need to be functionally and operationally sustainable amid changes in technological, political, socio-economical, financial, cultural and other environmental challenges. IJASM aims to promote and harmonize knowledge developments in the emerging fields of agile systems research, sustainability and vulnerability analysis, risk assessments methodologies, complex systems science, e-organisation and e-supply chain management, with emphasis on the international dimension, particularly breaking cultural barriers, and on national contexts, globalisation and new business practices. As such, we aim to publish papers presenting new research, innovative theoretical approaches, changes in agile management paradigms, and action (both examples of successes and failures as long as there are important lessons to be learned) from leading scholars and practitioners. Papers generally fall into two broad categories: those grounded in theory and/or papers using scientific research methods (e.g., reports of original empirical studies, models, critical reviews of existing empirical research, theory pieces that clearly extend current thinking); and those focusing on innovative agile approaches that are based on well reasoned extensions of existing research, experiential knowledge, or exemplary cases (e.g., thought pieces, case studies, etc).
