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: 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.
