Abstract

Background/Objectives: The adoption of cellular manufacturing becomes promising manufacturing philosophy to address the problems of today’s manufacturing plants such as an increasingly turbulent environment and rising customer requirements. Method/Statistical Analysis: Group Technology and Cellular Manufacturing System (CMS) have together paved way for the same through processing of similar parts groups as part families and the formation of a machine cell dedicated for the manufacture of the part family. The traditional CMS design methods do not incorporate many real-life manufacturing parameters such as batch size and machine flexibility, various cost factors at the design stage and also they are not taking the advantage of the machine flexibility in terms of coexistence of alternate process routing. Findings: In this work, a comprehensive mathematical model has been developed capturing these exact production parameters. An optimal solution is obtained using Lingo 8.0 software package and a solution methodology of best possible cell configurations is formed. Applications/Improvements: The effect of considering the alternate process routing in the design stage of CMS is evaluated and it is found that routing flexibility results in better cell configurations.

Abstract

Objectives: This paper reports an investigation that was carried out for modelling and structural analysis of cam shaft. Methods/Statistical Analysis: The modelling of cam shaft is carried out using the software solid works and the structural analysis of the model is carried out by using Ansys software. Initially, the model is designed with Solid works software and then it is converted into Initial Graphics Exchange Specification (IGES) file. Then it is systematically analyzed using the IGES model of cam shaft. Experimental results under static load containing the stresses and deflection are predicted cast iron material. Findings: Testing was carried out for unidirectional different materials like ductile cast iron, nodular iron and carbon epoxy. By considering these materials, it is noted that the ductile cast iron is a good material compared to the nodular iron because the breakage of nodular cast iron is higher than the ductile cast iron. Application\ Improvements: Ductile cast iron is considered for making the cam shaft in vehicles because the cost of material slightly higher than nodular iron. In the development of modelling and also analyse by software helps to better result in design.

Abstract

Objectives: This paper aims at studying force distribution characteristics and load with standing capability of a remodelled IC engine piston connecting rod arrangement where the conventional single piston single connecting rod arrangement is replaced by linking two pistons with a single connecting rod. Methods\Statistical Analysis: 3D Modelling of the arrangement is carried out using Solid works while force analysis of the model is done using ANSYS workbench. Parallel twin cylinder 4 stroke petrol engine is utilized as reference for creating the model and analysis purpose. Findings: The results gives the theoretical evidence that there can be a considerable reduction in engine weight and complexity with this new arrangement with stress, deformation and strain values lying within the boundary. Applications\Improvements: This arrangement gives extra room for lubricants thereby indeed indirectly increasing performance characteristics.

Abstract

Objectives: To compare the process parameters such as tool performance, surface roughness in turning process under, dry and near-dry conditions. Methods\Statistical Analysis: This study deals with the comparative performance of carbide coated tools in conventional dry turning with minimal lubricant application method by varying depth of cut keeping feed and speed as constant. The performance of the tool and the roughness of the work material under different conditions are analyzed. Findings: It is found that according to the selected cutting conditions in the model-based comparisons, the predicted tool wear under near dry lubrication are reduced as high as about 30% compared with those in dry cutting while the predicted tool wear land lengths are reduced by 60% compared with those in dry cutting. After the physical behaviors in near dry turning are understood, it is possible to calculate the tool life with given material properties and cutting conditions. Applications\ Improvements: This study gives sufficient information about performance of carbide tool with minimum amount of lubrication.
